How to wirelessly power IoT sensors from 10m away 

Did you know that one hundred batteries go to landfill sites every second? In this three-man ipXperience, Eamon is joined by Sanjay Gupta, President of AirFuel Alliance, and our familiar friend Nick Dutton from Atmosic to discuss how to make IoT a sustainable technology – Thanks for getting us connected, Nick! 

The AirFuel Alliance is an initiative set up to support the development, standards, and certification for truly wireless charging and power transfer. As Sanjay explains, standards are the best way to kick-start markets that use new technologies, and AirFuel’s standards aim to bring wireless power technology to the mainstream, supporting many applications from consumer electronics to IoT and more. 

Atmosic is a semiconductor company that focusses on ultra-low-power MCUs and wireless SoCs. The key differentiator with its technology is that RF energy harvesting is embedded within many of its devices, making them the perfect companion for AirFuel’s standards to eliminate the need for batteries in IoT products. Could this be the solution to solving IoT’s ‘battery issue’? 

In this chat, Eamon, Sanjay, and Nick discuss the various challenges of implementing this futuristic technology, covering the topics of whether IoT is green, the evolution of the IoT market, energy harvesting and energy budgeting in IoT sensors, safety of wireless power transfer, interoperability with other wireless technologies, and more. 

If you’re looking to power devices at a distance, check out Atmosic’s ATM34e Bluetooth SoCs by following the link to the board page below, where you can apply to evaluate this technology and get started developing wirelessly powered products.
