    Your local café may offer more than just free WiFi thanks to researchers at the University of Washington, who are developing a device to charge your phone battery through WiFi. Rather than watching your battery die, imagine that you could charge your phone or computer just by being within 28 feet of a router. Although charging stations have become available in public places, these stations are often useless if you don’t have your charger on hand.

     

    Vamsi Talla, a researcher for the project, states, “The goal of the sensors is to harvest RF (radio frequency) power and convert it into DC power.” There is already a similar device on the market, distributed by a company called Energous; however, this device fails to provide access to WiFi. Although Energous’ device is effective in eliminating unnecessary cords (tripping hazards), the device lacks the multi-functionality that customers want. Why pay for a standard WiFi router when you can draw in business by allowing your customers to leave their chargers at home?
