NATICK, Miss., Oct. 27 (UPI) -- The U.S. Army plans to field test a bionic PowerWalk system next year that generates battery power from a soldier's leg movements.
The "bionic power knee harvester" attaches to both legs and is designed to extract the energy expended when the knee is flexed and negative work is undertaken, the service said Thursday. It adjusts to individual gaits so it can go unnoticed by the wearer.
