‘Power Over Wi-Fi’ named one of the year’s Game-Changing Technologies

For the first time we’ve shown that you can use Wi-Fi devices to power the sensors in cameras and other devices,” said lead author Vamsi Talla, a UW electrical engineering doctoral student. “We also made a system that can co-exist as a Wi-Fi router and a power source—it doesn’t degrade the quality of your Wi-Fi signals while it’s powering devices.”

PoWiFi could help enable development of the Internet of Things, where small computing sensors are embedded in everyday objects like cell phones, coffee makers, washing machines, air conditioners, mobile devices, allowing those devices to “talk” to each other. But one major challenge is how to energize those low-power sensors and actuators without needing to plug them into a power source as they become smaller and more numerous.
