Something very strange happened in the R&D lab of a UK-based electronics engineering company. A research team at Roke Manor Research was working on text-based radio frequency systems when a team member suddenly detected a signal—coming from a random bag of components off to the side. A small movement had apparently turned mechanical energy into electrical energy within the bag.

After figuring out how this phenomenon occurred, a Roke team subsequently harnessed it and created a new tiny tracking device. Their invention works over a greater distance than most existing tags, and here’s the killer quality that makes it really different from nearly all tracking devices: It works without batteries.
