UW Advance Might Enable Wireless Devices Without Batteries

The University of Washington says its researchers have created a new, wireless communications system which uses ambient radio signals to power wireless communications devices, without the need for batteries. According to the University, engineers at the school have developed a technique called "ambient backscatter" which uses radio signals already present in the environment to communicate with each other, without using batteries. Those devices work by reflecting or absorbing existing radio signals to communicate, elimintating the need for batteries.
