ONiO builds microcontrollers that run without batteries — but that’s not the point.

Our chips harvest ambient energy — light, heat, RF — and just work. No wires. No recharging rituals. No maintenance loops.

We don’t believe batteries are evil. We just don’t assume they’ll always be there.

Our first chip, ONiO.zero, is a wireless microcontroller built from scratch to run on harvested energy. It cold-starts from under a microwatt. It runs BLE and other radios.
