Researchers at the University of Washington this year came up with an ingenious method to wirelessly charge electronic devices via an everyday Wi-Fi router. Appropriately dubbed Power Over Wi-Fi (PoWiFi), UW’s team of researchers have already managed to use the technology to charge a number of low-powered devices, including a low-res grayscale camera and a Jawbone activity tracker.

Specifically, researchers at UW were able to charge the camera module from a distance of 17 feet. With respect to the Jawbone, they managed to boost its battery level from 0 to 41% in 2.5 hours from a distance of 28 feet. Clearly, the ramifications of this technology are huge and incredibly exciting.
