UW engineers have developed a novel technology that uses a Wi-Fi router – a source of ubiquitous but untapped energy in indoor environments – to power devices. The Power Over Wi-Fi (PoWiFi) system is one of the most innovative and game-changing technologies of the year, according to Popular Science, which included it in the magazine’s annual “Best of What’s New” awards announced Wednesday.
Researchers earlier this year show how they harvested energy fr to further improve the efficiency of the system to enable operation at larger distances and power numerous more sensors and applications,” said co-author Shyam Gollakota, assistan...
