Your Wireless Internet Could Power Your Future Devices
• PopsciWi-Fi allows us to connect to the Internet by transmitting data through the air itself, but what if it could be used to power our devices wirelessly as well? Scientists at the University of Washington are currently working to make it happen.
PoWiFi, short for power over Wi-Fi, tricks routers into sending out a constant signal that's captured and converted into DC power by a harvester.
Wi-Fi already transmits a small amount of power to carry data, up to 1 watt by FCC guidelines, compared to the 5 watt output of a typical Android or iPhone charger. This technology captures that power that's already being sent, and puts it to work.
