An anonymous reader shares an article on Fast Co Design (edited and condensed for clarity): Researchers at University of Washington's Sensor Lab have created the WISP, or Wireless Identification and Sensing Platform: a combination sensor and computing chip that doesn't need a battery or a wired power source to operate. Instead, it sucks in radio waves emitted from a standard, off-the-shelf RFID reader -- the same technology that retail shops use to deter shoplifters -- and converts them into electricity. The WISP isn't designed to compete with the chips in your smartphone or your laptop. It has about the same clock speed as the processor in a Fitbit and similar functionality, including embedded accelerometers and temperature sensors. [...] It has about the same bandwidth as Bluetooth Low Energy mode, the wireless power-sipping technology which drives most Bluetooth speakers and wireless headphones.Read more of this story at Slashdot.
