Abstract

A method and apparatus are provided for supplying electric power in the form of an output d.c. voltage. An electret material emits the output d.c. voltage in response to continuously applying a high potential static field across the electret material. In a preferred embodiment, a central member is formed from the electret material and includes two spaced apart, oppositely facing contact surfaces. Two voltage input contacts are separately mounted to the two contact surfaces of the central member, each on opposite sides of an outer portion of the electret material. A static voltage source continuously applies a high static voltage potential across the two voltage input contacts to apply the high potential static field across the outer portions of the electret material. Two voltage output contacts are separately mounted to the two contact surfaces of the central member, on opposite sides of an inner portion of the electret material and spaced apart from the two high voltage contacts. In response to the very high potential field being continuously applied across the outer portion of the electret material, the atoms on the molecules of the electret material are electrically aligned to produce a current. The inner portion of the electret material develops an output d.c. voltage across the two voltage output contacts to thereby supply the electric power.
