NATICK, Mass. -- Today's warfighters may one day find themselves knee-deep in power. The bionic power knee harvester, also known as the PowerWalk, is an energy-harvesting device that is attached to both the upper and lower areas of both legs and generates power from movement. The device is still in development. Field trials will begin in 2017. The device is designed to extract the energy expended when the knee is flexed and negative work is being performed. The system adjusts to a person's gait, so Soldiers don't feel like they are wearing a device and can even forget that they have it on. "Just by walking, Soldiers could generate power," said Noel Soto, a project engineer at the Army Natick Soldier Research, Development and Engineering Center, or NSRDEC. "We are converting the movement of the knees when you walk into useful power." Soldiers now carry multiple electronic d...
