Novel Use of WI-FI Signals to Power Remote Devices, named PoWi-Fi The scientists from the University of Washington have devised a method to utilize Wi-Fi signals to power a battery-free camera, demonstrating the possibility of using Wi-Fi signals to broadcast power to remote devices. They have named the new approach as 'PoWi-Fi' signifying 'power over Wi-Fi'.In a report published in the MIT Technology Review, Vamsi Talla, an Indian origin scientist along with colleagues at the University of Washington in Seattle have asserted that Wi-Fi radio broadcasts are a form of energy and a simple antenna with the receivers can pick up this energy.Talla demonstrated his claim by connecting an antenna to a temperature sensor and placing it close to a Wi-Fi router. The resulting voltage in the device was then measured and it was observed for how long the device can operate on the remote power source. When the team connected a camera to their antenna, the results were remarkable.Talla informed," The battery-free camera can operate up to about five meters from the router, with an image capture every 35 minutes". Talla further said that by adding a rechargeable battery, the operating distance of the camera was increased to seven meters.Moreover, the researcher claimed that the router could even power the camera through a brick wall. The team also used Wi-Fi signals to charge a Jawbone fitness device from a no-charge state to 41% charged state in 2.5 hours.The MIT report stated that power-over-Wi-Fi could be the enabling technology that finally brings the 'Internet of Things' to life.
