UW’s “Power Over WiFi” named a top innovation of 2015 by Popular Science

UW WiFi powered surveillance cameraResearchers from UW CSE and EE announced in June that they had developed Power Over WiFi, “PoWiFi” for short, to harvest energy from Wi-Fi routers to wirelessly power devices. The technology, which has appeared in MIT Technology Review, Wired, BBC News, and several other media outlets, was chosen this week as one of Popular Science’s “Best of What’s New 2015” – a list of the top 100 innovations that the magazine believes will shape the future and change the world.

From the UW media release:

“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….

“Although initial experiments harvested relatively small amounts of power, the UW team believes there’s opportunity to make the PoWiFi system more efficient and robust.

“‘In the future, PoWiFi could leverage technology power scaling 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, assistant professor of computer science and engineering.”

In addition to Gollakota, the research team includes CSE and EE professor Josh Smith, EE graduate students Vamsi Talla, Bryce Kellogg, and Saman Naderiparizi, and former CSE postdoc Ben Ransford. They will present their final paper on PoWiFi at the ACM’s CoNEXT 2015 conference in Heidelberg, Germany this December.

Congratulations to the entire PoWiFi team!
