New gadgets through walking

Novel device has been built by the British scientist which can converts body movement into electricity capable of powering small gadgets such as GPS trackers. The device, made public this week in the July issue of the journal Smart Materials and Structures, is designed to be worn on the knee and harnesses the energy produced by walking.

The journal and researcher has said that it could be used to reduce the number of heavy batteries by the military. Its each weight is up to 10 kg that soldiers carry on foot patrol.

At the Universities of Cranfield, Liverpool and Salford, it was created by the researchers originally with funding from the UK Ministry of Defence. If it produced on an industrial scale the researchers estimate that it could retail for 10 pound.
