Battery-free microcontrollers powering the next wave of sustainable IoT

As the Internet of Things expands, so does the challenge of powering billions of devices without adding to the world’s battery waste. ONiO tackles this with a breakthrough microcontroller that runs entirely on ambient energy, harvesting power from light, heat, radio waves, or motion.

ONiO.zero integrates processing, connectivity, and power management on a single chip, enabling battery-free or ultra-low-power devices for applications in agriculture, logistics, retail, and smart buildings. No charging, just efficient, autonomous operation.

Founded by a team of engineers and deep tech specialists, ONiO is redefining what’s possible at the edge, making IoT smarter, cleaner, and more sustainable.
