Abstract
The electrical response phenomenon of electrostrictive polymers is used to harvest electrical power from the general movement of objects such as from human walking motion, for example. In a preferred embodiment of the invention, the polymer material is incorporated into the soles of footwear and is either full- or partial-wave rectified and then if desired converted to a direct current (DC) voltage level for suitable battery charging and the like.
