Battery-free wifi network inches closer to reality for IoT

Engineers at the University of Washington have further developed the short range, battery-free, wireless communication system they first showed off last year. The continued development is interesting with respect to the Internet of Things because it is able to use ambient radio signals as a power source, laying the path for the creation of networks of battery-free wireless sensors.

Engineers create battery-free network from ambient radio waves

Engineers at the University of Washington have successfully demonstrated a short-range wireless communications system that is not only battery-less but also makes use of ambient radio waves as the carrier channel. The project paves the way for the creation of peer to peer networks that can be created out of ‘thin air’.
