The <a href="https://www.horizon-enlightened.com/">ENLIGHTENED project</a> is an R&amp;D collaboration between twelve companies and research organisations, funded by the EU Horizon Europe program. The focus is on increasing the potential of photovoltaic (PV) technology for low-power, low-light applications - combining energy harvesting and flexible, printed electronics to meet the power and energy requirements of small electronics across diverse application segments, while pushing the boundaries of sustainability in electronics design and production. <a href="https://www.onio.com/products/onio-zero.html">ONiO</a> is proud to be part of this partnership, contributing with our unique ultra-low-power technology platform for managing energy harvesting and full control of wireless electronic systems.In the following, we will briefly discuss two of the key areas within ENLIGHTENED - energy harvesting and flexible electronic circuits - and how their combination can stimulate the emergence of a brand new class of better, more sustainable electronics.<h2>Energy harvesting</h2>We live immersed in ambient energy. Such energy exists in multiple forms and is essentially free: yes, it’s here for grabs! So, why are all our small electronic gadgets built around batteries instead of tapping into all this free energy?&nbsp;Truth be told, from a glance, batteries are relatively cheap and in many ways convenient. But if we stop a little to think about a product’s whole lifecycle, we stumble upon low battery (inevitably at the least convenient occasions!), multiple battery changes, drawers full of used batteries leaking nasty metals that most certainly end up in landfills… And, all of a sudden, costs start piling up and convenience slips away.But is there any better way? Back to that whole free ambient energy! With a little ingenuity, it is possible to craft devices to harvest energy from sunlight or artificial lighting, radio frequency waves, motion or thermal gradients, and use such energy to power electronics. The good news is that talented scientists and engineers have already crafted many such neat energy harvesting devices. The amounts of energy obtained aren’t huge, but, if used wisely, are more than enough to keep small electronic gadgets, like the ones typically powered by coin cells or alkaline batteries, up and running. This is where a combination of optimised energy harvesting devices and ultra-efficient power electronics becomes handy!Here, we are not going to enter into details about other forms of energy harvesting, but rather focus on the one starring in ENLIGHTED: light, and in particular low-intensity light, like typically found in indoor environments.There are diverse PV technologies that can be used to harvest light and, in particular, a number of emerging technologies focused on efficiently harvesting indoor light, such as dye sensitised solar cells (DSSC), perovskite-based or organic photovoltaic (OPV) cells. In a <a href="https://www.onio.com/article/power-of-light-ambient-energy-for-iot.html">previous article</a>, we provided an overview of key concepts, technologies and market players. The ENLIGHTENED project focuses on OPV technology provided by the project leader, <a href="https://www.epishine.com/">Epishine</a>. Epishine’s OPV modules are already best-in-class, providing high-efficiency, flexibility, seamless integration and low cost. Notably, OPV technology shows the lowest environmental impacts among competing alternatives. A large part of the project is dedicated to improving OPV technology (materials, design, integration and production) with a view towards mass-scale real-world applications within IoT and small electronics.<h2>Flexible printed electronics</h2>Electronic boards, so-called printed circuit boards or simply PCBs, are the backbone of any mainstream electronic device. Despite obvious improvements that span across the whole electronics industry, the foundational aspects of PCBs have remained stable over several decades. This means that the backbone of present day electronics is still very much rigid PCBs, based on subtractive production techniques using etched copper and stiff fiber glass composite substrate, commonly known as FR4. These can be produced in a cheap way in high-throughput automated industrial lines. However, traditional PCBs are bound to some serious limitations.First, the rigidity of FR4 means limited design flexibility: form factor and design of devices must be done around a stiff PCB board, and make room for one or more batteries (plus a battery hatch for changes). This is obviously very limiting when you think of wearables, smart clothing, biomedical sensors and the like. But also across other product categories like sensors, trackers or smart labels to be deployed, for instance, in industrial IoT or the automotive sector - where new form factors, size, thinness and flexibility can be game changers.Second, PCB production typically accounts for as much as 35% of the total environmental footprint of an IoT device, due to energy-intensive subtractive processes that use many chemicals and generate waste. Hence, if we want to make electronics more sustainable, then this must be one of the pressure points.The approach in the ENLIGHTENED project is to move into flexible or hybrid (rigid-flex) electronics, where circuits are printed on flexible polymeric substrates, such as PET, using conductive inks based on copper or silver. Hence, we move away from subtractive production processes, which are inherently wasteful, into more sustainable additive/printed techniques, while enabling thinner, lighter and flexible electronic system backbones. This will free developers for new form factors and new product typologies. The ENLIGHTENED consortium includes two companies specialised in printed electronics, <a href="https://www.tracxon.tech/">Tracxon</a> and <a href="https://flexoo.com/">Flexoo</a>, which are driving the development of new flex-board designs and respective manufacturing processes based on ink printing and SMD (surface mount device) component assembly.<h2>A flexible power module made for sustainable IoT products</h2>Part of the ENLIGHTENED consortium has been focused on developing a flex-board module for powering IoT devices. Energy is harvested by Epishine’s OPV cells and stored in small SMD or pouch supercapacitors or rechargeable batteries. <a href="http://ONiO.zero">ONiO.zero</a> provides system control and advanced energy management. The consortium has been testing different electronic designs, substrates and conductive inks to optimise the module. This module is intended as a power unit adaptable to diverse IoT or small electronic devices. The module can be connected to application-specific flex-boards or conventional PCBs for end product deployment. The size of the PV cell and of the energy storage element can be tuned to serve the requirements of different use cases.In conclusion, batteries and conventional PCBs have been solid contributors to the boom of wireless electronics and IoT devices. Yet, this legacy is proving restrictive as the industry explores new avenues in terms of design and product typologies, while facing increased pressure for sustainable alternatives. The ENLIGHTENED project intends to unchain developers from the legacy of batteries and rigid PCBs. The course is set: self-powered, flexible and sustainable electronics made possible!

Small wireless electronic devices sparked a revolution in the way we interact with each other and the world around us. Still, these devices are bound by some material constraints, namely the need to use batteries for power and reliance on rigid electronic boards. These restrict the degrees of freedom for product developers and designers with respect to final form factors, applicability and user interfaces. What about if we could have self-powered, flexible electronics and, on top of that, made in a sustainable manner? This is the challenge the ENLIGHTENED project has set to solve!

Lighting up electronics redesign

Think about it - This would have sounded downright ludicrous even 20 years ago. But over the past decade or so, we’ve been making rapid advances in this field - today, there is not a single area of human activity that hasn’t in some way been touched by the advent of the Internet of Things.&nbsp;This exponential growth is a result of some pretty pathbreaking innovation, no doubt - Incredible technological advances stacked on top of one another. Wireless sensors, bluetooth technology, Wi-fi, ML, AI - you get it - it’s a result of a whole bunch of advanced capabilities coming together - but what’s ironic is that in spite of all these tremendous advancements in ultra-low-power electronics, the majority of these devices still rely on batteries for their power.&nbsp;What’s wrong with them being battery powered?Where do we even begin?&nbsp;First off, let’s start with the sheer irony of the fact that the entire enterprise of IoT is predicated on the idea of untethered connectivity - i.e. unrestricted access and connectivity. Batteries, by definition, bring constraints into the mix - they have a limited capacity which means that they need periodic replacements or recharging.&nbsp;The IoT dream was realised on the promise of sensors and devices that can be deployed in the most far-flung, remote areas of the world, gathering and transmitting data seamlessly without being tethered to a power socket - but to be tethered to a battery isn’t that much of an improvement. After all, even the best batteries eventually run out.&nbsp;Not to mention the laundry list of annoying pain points that batteries come with - they are an environmental hazard and contribute massively to our <a href="https://unitar.org/about/news-stories/press/global-e-waste-monitor-2024-electronic-waste-rising-five-times-faster-documented-e-waste-recycling">massive</a> e-waste problem - use and throw batteries end up in landfills and oceans, spilling toxic chemicals into our water and food for years and years.&nbsp;The minerals that are required to manufacture these batteries are notoriously rare and very <a href="https://www.onio.com/article/environmental-cost-of-batteries.html">dubiously</a> sourced.&nbsp;They also represent a significant recurring cost to businesses that deploy large numbers of IoT sensors.&nbsp;Imagine a facility that deploys a thousand wireless sensors - if each of these sensors will require battery replacements - even if it is only once every few years - that adds up to a lot of labour costs and hassle.&nbsp;But in spite of all these obvious disadvantages, batteries have persevered and are in fact, the go to power solution for IoT devices even today.&nbsp;Why, though?Let’s find out!<h2>Risk aversion or hidden merit?&nbsp;</h2><a href="https://www.abiresearch.com/market-research/product/7784614-energy-harvesting-for-the-iot-addressable-">ABI Research</a> estimates that over 60% of current sensor deployments in industrial IoT environments are battery-operated, with minimal usage of state-of-the-art, <a href="https://www.onio.com/article/environmental-benefits-of-energy-harvesting.html">green</a> modalities such as energy harvesting.Moreover, there are <a href="https://www.idtechex.com/en/research-report/sensor-market/1038#:~:text=Global%20sensor%20market%20to%20grow,forecasts%2C%20segmented%20by%20sensor%20technology.">reports</a> that suggest that the IoT-battery market is actually growing, indicating that many companies still prefer the “tried and tested” batteries&nbsp; over potentially revolutionary, albeit unfamiliar alternatives.So, why is it that batteries continue to dominate the IoT sensor market in spite of so much pathbreaking innovation in the self-powered IoT arena?For one, engineers find them very easy to work with and design around. Companies have invested billions of dollars and decades of their time in perfecting Printed Circuit Board (PCB) layouts, mechanical housings and certification processes around battery-based semiconductor systems.&nbsp;<blockquote>Batteries are simply not the future-proof power solution that IoT’s next evolution demands, but an abrupt pivot to fully batteryless systems isn’t realistic either. Instead, the industry is looking toward transitional solutions—methods that recognize our present limitations but also nudge us toward more sustainable, self-powered approaches over time.</blockquote>There are very well-oiled supply chains that have been established around these products worldwide to enable fast prototyping and mass-production. Moreover, battery-based designs fit very neatly into existing regulatory frameworks, making it easier for companies to bring these products to market.&nbsp;Moreover, we’ve managed to create highly standardised modalities to measure battery capacity which makes it very easy to incorporate battery-related components into devices.&nbsp;Another major factor is form. OEMs have designed the form factors of their product lines around standard battery types - such as AA, AAA, coin cells - you name it. We understand the voltages, capacities, lifespans and capacities of these batteries and therefore, have modelled our designs to fit these widely available power solutions.&nbsp;This one might be obvious, but batteries are a product that boast of very well entrenched supply chains - they are manufactured by very large and well connected players - they make their way from factory floors to local distributors seamlessly, making it very cost effective, upfront,&nbsp; for companies to design their products around them.&nbsp;So, does this mean, we just accept the status-quo for what it is and not do anything about it?No Way!I think the trick here is to not take a zero-sum approach - it is essential to see the merit in both sides of the argument - there are a number of reasons why batteries still make practical sense for large-scale use in IoT - especially industrial IoT - and can’t be phased out instantaneously.&nbsp;But equally, we just can’t hide from the fact that we do need to start phasing them out at some point in the near future - they simply don’t belong in the high-tech connected world that we are creating - the world of AI, ML and edge computing. They are a stop-gap solution at best and it is imperative that we recognise this.&nbsp;They are not the future-proof power solution that the future of IoT demands from us - but here’s the thing - we’re not going to make a sudden leap - things never work that way. We need a gradual transition - we need solutions that are pragmatic enough to recognise our present limitations while being visionary enough to propel us towards the future, in whatever capacity they can.&nbsp;Many use-cases can benefit from a middle-of-the-way approach that doesn’t throw the baby out with the bathwater - an approach that integrates energy harvesting into existing battery-powered designs in order to bolster their lifespans and reduce their environmental footprint.&nbsp;Before we explore the hybrid approach, it is essential to answer this question - why bother making the shift at all?Firstly, there’s the elephant in the room - sustainability. We all bear a massive responsibility to hand over the planet in good shape to the generations to come. The e-waste crisis has reached an extent where we simply can’t ignore it any longer - reducing our battery turnover will have a direct impact on how many batteries end up in landfills and oceans. There’s also the indirect effects - fewer maintenance trips, lesser battery production and ergo, a smaller carbon footprint.&nbsp;Secondly, it just takes us closer to the original IoT dream - which was that of frictionless, untethered, “set-it-and-forget-it” sensing. Hybrid sensors bring us closer to that dream and batteryless sensors truly enable that dream - this is especially true in remote deployments and in harsh environments, where battery swaps are close to impossible.&nbsp;<h2>The Hybrid Approach - Bridging the Gap</h2>In recent years, energy harvesting technologies have emerged as by far the most compelling alternative to batteries when it comes to IoT power solutions. They enable truly batteryless sensors that are able to power themselves by energy harvested from their surroundings.&nbsp;We might not realise it, but there are swirling cascades of energy all around us at all times - energy harvesting technologies allow us to capture small packets of this energy and convert it into usable electricity that can power sensors and keep them untethered.&nbsp;There are a number of standards that have emerged in the past decade&nbsp; as viable contenders - RF energy harvesting, piezoelectric energy harvesting, photovoltaic energy harvesting etc.&nbsp;Energy harvesting powered sensors are cleaner, more economical (over their lifetimes) and more compact than their battery powered counterparts. However, as we saw earlier, there are other concerns that stop them from being adopted en masse.&nbsp;That’s why hybrid solutions are quickly becoming the sweet in-between option for manufacturers looking to get the best of both worlds. There are two schools of thought around these hybrid devices - the first one is to think of the battery as a safety net - the device primarily draws power from ambient sources and only taps into its battery when it needs a boost or when environmental conditions make energy harvesting difficult.&nbsp;The second one is to see the energy harvesting as a boost to the battery - increasing the battery life exponentially by reducing the load. Either way, these solutions are starting to make a lot of heads turn with their versatility and massive scope.&nbsp;&nbsp;They minimise disruption - manufacturers don’t have to overhaul entire product lines and supply chains. They increase reliability and scalability as we gradually build towards a totally batteryless future.&nbsp;So, what does a hybrid solution look like?Partial Energy Harvesting - You add a mini solar cell, RF harvester, or other ambient energy capture mechanism alongside the existing battery. This means the sensor can sip on harvested energy most of the time and only dip into battery reserves when ambient sources aren’t sufficient (e.g., at night or in signal-poor locations).Extended Battery Lifespan - By running off harvested energy whenever possible, the battery drains more slowly—significantly cutting down on replacements, maintenance trips, and environmental impact.No Major Overhaul - From an engineering perspective, you don’t have to scrap your entire product line or redesign from scratch. If you’ve already got standardized PCBs, enclosures, and supply chains for your battery components, you can often incorporate energy-harvesting modules with minimal disruption.<blockquote>One reason battery-based devices remain prevalent is the sheer familiarity of design processes. Engineers know exactly how to choose and test AA or CR2032 coin cells, and OEMs can count on a robust, global supply chain to source these components. According to ABI Research, more than 60% of current industrial IoT sensors still run on traditional batteries—a testament to the comfort and reliability that comes with well-understood power solutions.</blockquote>But why exactly does this hybrid model matter beyond the theoretical? Let’s get a bit more tangible—it helps to picture specific, real-world scenarios that show just how big an impact even partial energy harvesting can have.<h2>Bringing Hybrid to Life: Real-World Scenarios</h2><h3>1. Remote Farmland Sensors</h3>Imagine an agricultural setting with hundreds of soil moisture and temperature sensors spread across fields. Typically, these sensors run on coin cell batteries and last around 2 years before dying. A hybrid approach—adding a small solar panel or basic RF harvester—means the device draws ambient energy for most operations and sips on battery only when conditions are poor. Suddenly, that 2-year lifespan might double to 4 years or more.<h3>2. Industrial Warehouse Tracking</h3>Picture a vast warehouse with inventory-tracking tags on conveyor belts, pallets, and shelves. Most of these tags might last about 18 months on a small coin cell. But if you integrate a kinetic harvester (energy from motion) or exploit the constant hum of Wi-Fi signals, that battery might stretch to 3 years or more.Minimal Disruption: You don’t have to overhaul your entire warehouse workflow—just embed a harvesting module where the battery slot already exists.Extended Battery Lifespans: Doubling the life of each tag slashes replacement labor, making your entire operation smoother and more cost-effective.Strategic Scalability: As your company adds more sensors, you’re not exponentially increasing battery headaches—each new sensor can partly power itself.<h3>3. Shipping Container Trackers</h3>Consider GPS-enabled trackers attached to shipping containers moving across seas, rail lines, and trucks. Traditionally, these trackers need battery replacements every 6–8 months—which is no small feat when containers are constantly on the move. With a small solar panel on top, the device relies mostly on harvested energy during daylight, dipping into the battery only at night or in covered storage. That extends operational life to 2 years or more.Significant Maintenance Cuts: Fewer global hunts to locate each container and swap batteries.Continuous Visibility: Fewer dead trackers means less risk of losing cargo data in transit.Eco-Friendly Edge: Shipping companies can tout sustainability gains, appealing to both regulators and eco-conscious clients<h3>4. Healthcare Wearables</h3>Think about a patient-worn armband that monitors vitals in real time. Normally, it needs charging every couple of days—which many patients forget, creating data gaps. By integrating motion-based or RF-based harvesting, you can push that charging cycle out to nearly a week for some users.Better Compliance: Patients are more likely to keep wearing the device if they don’t have to charge it constantly.Improved Healthcare Outcomes: Continuous monitoring (fewer missed days) means earlier interventions if anomalies arise.Foundation for Batteryless: Once the wearables can reliably gather enough ambient energy, the battery can shrink or vanish entirely—especially valuable for remote patient monitoring in underserved areas.<h1>Making the Most of a Hybrid Model</h1>Whether it’s farmland, warehouses, shipping, or healthcare, partial energy harvesting can have massive ripple effects. Let’s connect the dots on why hybrid systems solve more than just the “battery annoyance” factor:Reduced E-Waste Even if you don’t achieve 100% batteryless operation, slashing battery replacements by half—or even a quarter—adds up to a monumental environmental win. Over a large fleet of sensors, fewer spent batteries in landfills means a smaller overall carbon footprint.Lower Operating Costs Every battery swap typically involves manual labor—someone has to locate the sensor, open it up, replace the battery, ensure it’s functioning again, and log the event. Multiply that by hundreds or thousands of nodes, and it’s a significant cost sink. When you extend battery lifespans with energy harvesting, you drastically reduce these site visits.Stepping Stone to Batteryless The infrastructure you build now—using low-power MCUs, partial harvesters, and redesigned PCB footprints—lays the groundwork for an eventual transition to fully battery-free devices. As energy-harvesting technology matures (improving cold-start capabilities, boosting capture efficiency), you can phase out the battery entirely in future device iterations.<h1>Keeping It Organic</h1>But let’s not forget the bigger picture: These scenarios and benefits aren’t just nice bullet points—they form part of a broader narrative about IoT’s natural evolution. We moved from wired sensors to battery-powered sensors because it freed us from wall sockets. Now we’re moving from battery-only to battery-plus-ambient-energy because it reduces cost, maintenance, and e-waste. Eventually, we’ll reach a point where ambient energy alone is enough in many (though not all) situations.“This is less of a revolution and more of a gentle shift,” says an imaginary IoT project manager. “We’re not throwing out our existing designs overnight. But every time we update a sensor, we add a tiny harvester. After a few generations, we’ll see how much we’ve cut down on batteries—and that’s a big deal.”The key is recognizing that batteries aren’t evil nor are they a permanent fixture. They’re simply tools that served a purpose for a while—and in many cases, continue to serve a purpose. But as IoT scales to tens of billions of devices, the environmental and economic downsides become too large to ignore. Hybrid energy solutions, in this sense, represent a pragmatic path—one that acknowledges our reliance on batteries but also paves the way for a more autonomous IoT.<h1>Conclusion: Embracing the Hybrid Mindset</h1>Ultimately, hybrid power solutions answer two pressing questions:How do we reduce battery replacements now? andHow do we transition smoothly to batteryless IoT in the future?By adding small but powerful energy harvesters—like solar panels, RF collectors, or piezoelectric elements—manufacturers and deployers can keep their existing battery-centric infrastructure and supply chains, yet dramatically reduce how often those batteries need replacing. That’s a huge win for the environment, a win for operational budgets, and a win for the original IoT vision of unfettered connectivity.So, while batteries remain the status quo, we don’t quite have to turn a blind eye to the serious limitations that they bring to the table. Challenge your designs, incorporate some ambient energy capture, and watch as your device runtimes stretch, your maintenance costs drop, and your brand reputation shines. The true promise of IoT—“deploy anywhere, run forever”—may be closer than we realize, and hybrid solutions are the stepping stones that will get us there.

We are in the midst of an IoT explosion - there’s no two ways about it. According to IoT analytics’ state of IoT report 2024, the total number of connected devices in the world as of 2021 was 12.3 billion! This number is slated to exceed 27 billion by the end of 2025! 

Make no mistake, that’s a tremendous achievement, technologically speaking. To the uninitiated, that means that we’ve managed to connect billions upon billions of objects to the internet - objects that, for the most part, don’t belong in the realm of traditional computing devices such as tablets, computers and smartphones. That’s nothing to sneeze at!

Batteries or Energy Harvesting - Can’t It Be Both?

Senior Content Manager

Abishek Swaminathen

Still do, to a degree.But lately, we’ve been sitting with it. Looking at what we’ve built. Talking to people. Watching how our story has landed out in the wild. And it’s become clear:We need to tell the whole truth now.<h2>Why we told the batteryless story to begin with</h2>Let’s rewind.When we started ONiO, we weren’t trying to be yet another MCU vendor with a clever logo and a new benchmark.Honestly, we were terrified of becoming invisible — just another piece of silicon with slightly better power figures and a PDF nobody reads.So we did what we had to do:We found a story.And it was a good one.Batteryless wasn’t just a gimmick. It was our origin — a design constraint that forced us to think differently. How do you build something that can cold-start from ambient energy alone?That question led us to ONiO.zero.It also gave us something way more rare: an actual identity.In a sea of suit-and-slide-deck semiconductor companies, we stood out. We felt like… people. With a point of view.<h2>We also knew we didn’t want to look like the rest of the industry.</h2>No face, no voice — just PDFs and jargon, occasionally interrupted by a press release or a talking head wandering the exhibition floor, badge swinging, rehearsing the same three phrases to a gimbal.<figure class="image"><img src="https://res.cloudinary.com/onio/image/upload/v1744202551/onio_off_to_ces_39c8b6901f.jpg" alt="onio_off_to_ces.jpg"></figure>You know the type: coffee in hand, LinkedIn post ready - “Off to CES - let’s gooo 🚀”We weren’t interested in that.We wanted a brand that felt like us: curious, sharp, design-forward. A little weird. Human.So we built something people could connect with. A chip, yes — but also a story, a tone, an unique visual language. Something that didn’t just talk at people, but invited them in.A chip can be beautiful. So can the story that carries it.And batteryless gave us a way to say all of that in one word.<h2>The problem with one story</h2>But here’s the flip side of telling a strong story:Sometimes people only hear that story. And nothing else.We got pegged.As the batteryless guys. The purists.The ones who build fruit-powered demos and do firefly math.And to be honest — we love that part.We still do it.It’s fun. It makes people think. And it’s real.But somewhere along the way, people started assuming that was all we were.And in letting that story lead, we may have oversimplified our own reality.Because the truth is, most real-world applications aren’t black or white.Some are perfect for batteryless. Some need a supercap. Some are better off with a rechargeable cell. Others just want 10x battery life and no drama.We’ve always known that.We just didn’t talk about it enough.<h2>So what’s actually true?</h2>What’s true is this: ONiO.zero is an absurdly low-power, wireless RISC-V microcontroller that can run on harvested energy — from light, RF, whatever.In the right conditions, you really can skip the battery entirely.But that’s not the only way to win.Maybe you want a BLE-connected sensor that lasts five years on a tiny coin cell.Or a smart label that never needs charging.Or a soil monitor with a solar panel and a little backup.Or a keyboard that powers up as you type.That’s the world we’re building for.We didn’t set out to kill the battery.We set out to design like batteries weren’t guaranteed.<h2>What we actually believe</h2>We believe in designing for power independence.Not as a feature. As a mindset.We believe maintenance is the real enemy.That good design feels invisible.That “energy harvesting” shouldn’t sound like science fiction.And that in a few years, asking “how long does it last?” will feel weird — because the answer will just be: as long as you want.<h2>We’re still ONiO</h2>We still love weird builds and scavenged power and the elegance of restraint.We still care about making semiconductors that don’t feel like they came out of a corporate birth canal.But more than anything, we care about telling the truth — and telling it well.So yeah, we’ll still write about the joy of batteryless design.But we’re also going to show what it looks like to build real systems, with real constraints, in the real world.Some of those will have no battery.Some will have a battery that barely gets used.And some will plug in. That’s okay too.The point isn’t purity.The point is possibility.<h2>In the end</h2>We’re not trying to win a sustainability badge.We’re trying to help engineers design smarter systems - ones that last longer, waste less, and just work.If that means no battery, great.If that means fewer batteries in better places, even better.We’re still ONiO.We still build chips that run off the air.We’re just not limiting ourselves to one storyline anymore.Because the story we’re writing now?It’s bigger. And more fun. And way more real.

Let’s be honest. 

We’ve been riding the “batteryless” wave pretty hard for a while now. 

If you’ve followed ONiO at all over the last couple of years, you’ve seen it: 

No batteries. No maintenance. Save the planet. Coin cells are evil. That whole thing. 

And, yeah — we meant it.

<h1>Sustainable electronics disentangled</h1>Sustainability is taking centre stage in many business sectors and the electronics industry is no exception. Yet, when we look deep into the newest electronic devices around us, are these really fundamentally more sustainable than the ones we were used to 10 or 20 years ago? In this article, we will look into how to make IoT and small electronic devices more sustainable, namely through energy harvesting. In doing that, we will introduce the SELECT project, where ONiO and a group of strategic partners are bringing together unique building blocks to enable a more sustainable future for electronics.IoT nodes and small, portable electronic devices are an integral part of today’s increasingly digitally connected society. The <a href="https://iot-analytics.com/number-connected-iot-devices/">number of connected IoT devices</a> was estimated at 19 billion in 2024, projected to grow to more than 40 billion by 2030. Yet, the growth of IoT seems to be lagging behind compared to some of the earlier prognostics, which have, for instance, pointed to <a href="https://community.arm.com/cfs-file/__key/telligent-evolution-components-attachments/01-1996-00-00-00-01-30-09/Arm-_2D00_-The-route-to-a-trillion-devices-_2D00_-June-2017.pdf">one trillion IoT devices produced until 2035</a>. One of the major bottlenecks limiting further scalability of present and future IoT is power and, in particular, the reliance on pervasively spread battery-powered devices. At the same time, the scale of deployments raises deep concerns with sustainability, concerns which spread across IoT, small electronic devices, and the electronics industry at large.<h2>Sustainability: beyond the buzz&nbsp;</h2>Despite all the buzz around sustainability over the past decades, truth be told, the core materials and the pillar principles of electronics design for mass production remain pretty much unchanged. Yet, the industry has a growing pool of more sustainable options on the table nowadays, and it’s time to turn the talk about sustainability into real, impactful actions.It is not difficult to find grand vision statements about sustainability from large electronics corporations in the past few years. For instance, back in 2021, <a href="https://www.itweb.co.za/article/samsung-in-green-push-for-tv-line-up/xnklOqzLgx974Ymz">Samsung announced</a> that its TV business was on a journey of “going green”. Among the action points was the introduction of solar-powered remote controls that, according to the company, could help prevent waste from 99 million AAA batteries over seven years. Another example is <a href="https://www.theverge.com/24206847/logitech-ceo-hanneke-faber-mouse-keyboard-gaming-decoder-podcast-interview">Logitech’s plan</a> to reduce its carbon footprint by half, including the introduction of long-lasting hardware like the “forever mouse” concept.Despite all the nice talk and good intentions, the electronics industry in general, and the IoT and small electronics segment in particular, is facing strong challenges with sustainability. The industry still relies on raw materials that are highly polluting (e.g. heavy metals in batteries) and greenhouse gas-intensive (e.g. conventional printed circuit board laminates), and their replacement is quite challenging from technical and cost perspectives. A resolute stab at sustainability requires looking into every single component of an electronic system and the whole system’s life cycle. The market actors that do not take this seriously risk being severely penalised by customers and consumers, who are increasingly awake to signs of frail ESG policies and greenwashing.<h2>Energy harvesting gaining momentum</h2>A growing number of IoT-connected devices, including the ones with low-power consumption (1 micro Watt to 1 milli Watt range), continue to rely on disposable or rechargeable batteries. Yet, batteries are far from being a good solution for powering small electronics, especially single-use coin cells or alkaline power cells typically used in such devices. Small devices reliant on batteries are a problem for several reasons. On the one hand, the limited lifespan of batteries and the high costs and burden associated with battery replacement and device maintenance can become a logistical nightmare in very large distributed node systems. On the other hand, the social and environmental problems associated with the lifecycle of batteries and respective raw materials such as <a href="https://www.onio.com/article/environmental-cost-of-batteries.html">lithium and cobalt</a>. In a nutshell, batteries are bound to represent an apparent bottleneck in the massive deployment of IoT devices and a huge environmental problem. Therefore, it becomes clear that players serious about sustainability must look into batteries and consider better alternatives whenever possible.&nbsp;That’s where <a href="https://www.onio.com/article/ambient-energy-world-of-iot.html">energy harvesting</a> comes into play. The market arena for energy harvesting, aka <a href="https://www.bluetooth.com/wp-content/uploads/2024/01/MRN_Ambient-IOT.pdf">Ambient IoT</a>, is growing in importance. The use of energy harvesting for small electronics is not entirely new. For instance, portable electronic devices such as calculators and watches powered by small photovoltaic panels were popular during the 1980s and 1990s. Yet, that trend did not pick up, and batteries have taken over the business of powering small portable electronics almost entirely. Now, the growth of the IoT together with technical progress in ultra low power electronics and ambient energy harvesting are providing a new opportunity for energy harvesting.&nbsp;The emergence of new ultra low power microchips, such as <a href="https://www.onio.com/products/onio-zero.html">ONiO.zero</a>, and new harvesting technologies, such as <a href="https://www.epishine.com/">Epishine</a>’s very efficient photovoltaic cells, are revamping the interest in energy harvesting. Early examples of use cases include asset tracking, condition-based monitoring, cold-chain monitoring, building automation and home control. The total market opportunity is <a href="https://www.bluetooth.com/wp-content/uploads/2024/01/MRN_Ambient-IOT.pdf">sized at trillions of units</a>.<h2>A change in mindset: electronics design for energy harvesting</h2>The design and development of electronic devices for energy harvesting requires a fundamentally different approach than the usual development for battery power. Energy harvesting typically generates only minimal amounts of power, meaning that the electronic circuits and systems must be tuned for extreme power performance and flexibility. Besides, ambient energy is often available in variable levels and intermittent modes. For instance, light levels are variable in most environments, and the same goes for radio frequency sources, depending on proximity to antennas, routers, mobile phones, etc. Hence, power management strategies must be designed for intermittent energy availability. Summing up, the electronic systems must be capable of harvesting under the most demanding conditions (e.g. very low light or weak radio frequency sources), run from ultra low power levels, store and manage any excess energy in the best way possible. By the same token, energy budgeting and duty cycle planning are keystones for seamless batteryless operation from ambient energy - emphasizing the importance of a crystal clear understanding of the requirements for each application and use-case.As a minimum, a functional energy harvesting device/system needs the following building-blocks: (1) one or more energy harvesters, harnessing ambient energy from light, radio frequency, motion or thermal gradients; (2) integrated circuits for control, processing and communication; (3) an energy storage/buffer element; (4) the load(s), i.e. the element(s) being powered, which may include sensors, transmitters, controllers, etc. These and a few additional auxiliary components must be mounted on an electronic printed circuit board (PCB). The SELECT project focuses on each of these elements and their seamless integration for deploying sustainable electronics with energy harvesting.<h2>The SELECT project</h2>The SELECT project brings together six partners on the quest for sustainable electronics. The project is co-financed by the <a href="https://eurekanetwork.org/programmes/eurostars/">Eurostars program</a>.ONiO leads the way with its ultra low power microcontroller tailored for energy harvesting, <a href="https://www.onio.com/products/onio-zero.html">ONiO.zero</a>, at the core of the project. <a href="https://www.onio.com/products/onio-zero.html">ONiO.zero</a> combines an <a href="https://www.onio.com/article/onio-riscv-coremark-results.html">ultra power-efficient RISC-V CPU</a> with an advanced power management integrated circuit (PMIC) and wireless radio communication on a single microchip. Epishine provides highly efficient and versatile printed organic photovoltaic cells optimized for indoor conditions, which are <a href="https://www.epishine.com/technology/lca">best-in-class with respect to sustainability</a>. <a href="https://www.lignaenergy.com/">Ligna Energy</a> owns unique supercapacitor technology that leverages bio-based sustainable materials and roll-to-roll manufacturing methods for green, safe and ultra-thin energy storage. <a href="https://www.jivamaterials.com/">Jiva Materials</a> offers Soluboard®, a fully recyclable and biodegradable rigid PCB laminate with a 67% lower carbon footprint than glass-fibre and epoxy technologies used in conventional FR-4 PCBs. These four partners put in the key ingredients for the SELECT recipe. The consortium is complemented by two end-user partners: <a href="https://www.pricer.com/">Pricer</a>, a partner for in-store communication and digitalization and a leading supplier of Electronic Shelf Label (ESL) solutions, and <a href="https://www.4modtechnology.com/">4MOD Technology</a>, a versatile company specialising in the design and engineering of remote controls and IoT solutions.The team will tune each of the key ingredients (microcontroller, photovoltaic harvester, supercapacitor, Soluboard® PCB), focusing on solving the challenges involved in their orchestration to work optimally together. These components are already available now, but their combination brings benefits to the next level. The project will generate reference boards and development kits combining these key elements - i.e. forming a SELECT platform ready to use in the development of a new order of sustainable IoT and small electronic products.The new SELECT platform will be able to serve a wide range of applications across the IoT and small electronics market verticals. During the project, the partners will focus on two lead applications: ESLs, under Pricer’s leadership, and remote control units, headed by 4MOD Technology. The key outputs of the project will include reference designs and prototypes customised for these two demo cases. But the SELECT platform will be ready to target an array of additional product categories, with a view to fast-tracking energy harvesting-based solutions to real market products that can effectively compete with the current battery-based standards.SELECT is using some of the most sustainable components available, with benefits in toxicity and contamination of the environment and particularly in carbon emissions. A back-of-the-envelope calculation shows a potential for saving at least 150.000 tonnes of CO2 equivalents per year if the SELECT solutions were rolled out across the ESL and remote control markets (estimated at 300 and 400 million units per year, respectively). This is the equivalent of taking over 100.000 combustion engine cars off the streets. These savings were estimated from removing single-use batteries and using photovoltaic harvesters instead, plus replacing FR-4 PCB with Soluboard®. The SELECT project includes systematic Life Cycle Analyses where the environmental benefits will be studied in detail and computed in a proper manner. In any case, looking at these ballpark calculations for the two test cases only, and considering the total space of applications that can be targeted by SELECT - extending from industrial IoT sensors to building automation, electronic tags and trackers, wearables, etc. - the extent of the project's impacts can be massive.<h2>Conclusion</h2>The tools to make IoT and small electronic devices way more sustainable are already on the table today. But we need to move from individual eco-friendly components to systems fully orchestrated to work optimally with more sustainable options such as energy harvesting. The added value of the SELECT solutions lies in the seamless integration of sustainable building blocks to craft an electronics development platform built with a 360º view on sustainability, from individual components to system level.&nbsp;Besides focusing on performance and sustainability, the SELECT platform will enable the deployment of very cost effective products and systems, especially when considering system bill-of-materials and lifetime costs. By removing batteries and simplifying electronic systems, SELECT will reduce the component count and footprint of electronics, with a positive impact on costs. Hence, SELECT will bring unprecedented possibilities in terms of thinness, material minimization and low cost of end devices. Moreover, with no battery changes, maintenance and lifetime costs will be much reduced, bringing logistics and cost benefits for the end users. Finally, for many product categories, the device’s lifetime will be extended and costs with end-of-life, namely recycling, will also be reduced.The SELECT partners' ambition is bold: mastering energy harvesting while redefining electronics with sustainability at the core. Power is on!

A New Era of Green Electronics: BeFC and ONiO Launch Strategic Partnership

This move reflects a growing recognition that ambient energy—light, RF, heat, vibration—is abundant but not always predictable. While ONiO.zero, ONiO’s flagship microcontroller, can start from under a microwatt and run on mere slivers of power, for certain use-cases it still needs a way to buffer and deliver energy reliably. That’s where VINATech becomes mission critical.Supercapacitors offer something batteries don’t - the ability to charge and discharge rapidly, last through countless cycles, and endure harsh environments. Their inclusion in the ONiO ecosystem enables longer-lasting, maintenance-free devices across industries—from shelf labels and air quality sensors to industrial tags and smart buttons.Rather than lock developers into a fixed stack, ONiO is curating a flexible ecosystem that enables design freedom while ensuring performance. VINATech’s Hy-Cap line complements ONiO’s flexible hardware stack, giving developers proven, production-grade options for buffering ambient energy. The result: faster prototyping, simpler power design, and hardware that behaves predictably in the wild — like a postage-stamp-sized PCB running a full ambient energy stack: harvester, VINATech supercapacitor, and ONiO.zero.This partnership is one of several ONiO is cultivating to expand its batteryless toolkit. VINATech’s supercapacitors aren’t a lab experiment — they’re already powering millions of commercial devices, including Samsung’s latest solar-powered TV remotes. That kind of field-tested reliability fits ONiO’s practical philosophy: build for power independence, not theoretical perfection. As ambient-powered designs go from demo to deployment — and take advantage of the fact that supercapacitors like VINATech’s are not classified as batteries under EU regulations, these are the kinds of components that make it possible.<h2>About VINATech</h2>VINATech is a South Korean manufacturer of high-performance energy storage components, including hybrid and EDLC supercapacitors. Its Hy-Cap® line is known for rapid charge/discharge, long life, and stability in extreme conditions.
