A team of boffins working for the University of Washington's Sensor Lab have worked out a way of taking the battery out of mobile devices and keeping them powered by radio waves.
Researchers there created the WISP, or Wireless Identification and Sensing Platform which combines sensors and a computing chip that doesn't need a battery or a wired power source to operate. It is powered by radio waves emitted from a standard, off-the-shelf RFID reader and converts them into electricity.
