Benefits
One Chip Many Benefits
Not only do you get better performance, more flexibility and substantial usability gains - It’s also way easier on your pocket.
High Integration.
Smaller BOM.
By combining radio, MCU, memories, and PMIC into a single package, we’ve simplified design and reduced component costs. That’s better for your budget and your devices.
Power Freedom.
Your Way.
Go battery-free or extend battery life dramatically. Reduce maintenance costs and deliver solutions that last longer and work smarter.
IoT
Unleashed
IoT liberated from power constraints. Whether battery-free or ultra-long battery life, there's no limit to where IoT can go.
Smaller Bill of Material
Save 60 – 80% on your BOM
Instead of playing with pennies - we turned to the dollar. We integrated radio, MCU, memories, and PMIC in a single package. For most applications that lead to one or two ICs less than the competition plus all the saved external components.
A typical competing solution would save on average a few external passive components which cost 7 cents.
Assuming 5 components for a typical design of 100.000 units, you save $35.000. Now consider the average cost of over $2 for an energy harvesting PMIC for RF or PV. For 100.000 units, that is $200.000.
ONiO.zero includes both RF and PV, and needs almost no external components. You can save over 80% compared to off-the-shelf PMIC energy harvesting solutions.
Environmental Benefits
The planet says Thank you!
Batteries have powered incredible advancements—but they come at a cost.
They contribute to waste, strain resources, and harm ecosystems.
ONiO is leading the charge toward a smarter future with solutions that reduce battery reliance, extend their life, or eliminate them entirely. Together, we can power the Internet of Things sustainably.
Material Savings (Kilo Tons)
Based on expected number of IoT devices in 2035
Scarce Supply
Demand for Cobalt will outstrip supply by the year 2030 - Cobalt is an essential component in the batteries that power our modern-day consumer electronics. A move to energy harvesting will reduce our dependence on non-renewable minerals such as LIthium, Cobalt, Manganese etc.
Unsustainable
There’s a massive humanitarian cost to every single battery that we use and throw - Lithium and Cobalt mining leave thousands of children sick for life and devastates entire communities in South America and Africa. Progress simply can’t be this loopsided and cruel.
