Haila, e-peas partner for Wi-Fi powered by light
Haila Technologies has teamed up with energy harvest PMIC provider e-peas Semiconductor to showcase a battery-free Wi-Fi backscatter chip powered by ambient light.
The partners claim the demonstration shows a path to extreme long-life energy storage for Wi-Fi connected wireless sensors.
Haila Technologies Inc. (Montreal, Canada) was founded in 2017 and uses a backscattering technique to modulate digital sensor data on top of the ambient signals of multiple protocols.
The use of harvested energy in sensors networks is attractive as it can reduce or eliminate the use and replacement of batteries, thereby reducing sensor network operating costs and environmental waste.
The BSC2000 RF evaluation chip is HaiLa’s monolithic implementation of passive backscatter technology adapted to Wi-Fi RF bands. The e-peas AEM10941 is an integrated energy management circuit that extracts DC power from up to 7 photovoltaic cell elements to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. AEM10941 PMIC for photovoltaic energy harvester allows battery lifetime extension and ultimately eliminates the disposable battery energy storage element in a large range of wireless applications.
