University of Washington 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 2015” awards announced Wednesday
The technology made headlines earlier this year when researchers published an online paper showing how they harvested energy from Wi-Fi signals to power a simple temperature sensor, a low-resolution grayscale camera and a charger for a Jawbone activity tracking bracelet.
The final paper will be presented in December at the Association for Computing Machinery’s CoNEXT 2015 conference in Heidelberg, Germany, on emerging networking experiments and technologies…..READ MORE
