Power generator

摘要

An electrical power generator has one or more serpentine elements that are made of a poled piezoelectric or electrostrictive ceramic, one or more electrically conductive shims or foils and at least two electrically conductive electrode coatings on the serpentine element. The conductive electrodes are further electrically connected to an electrical load or energy storage device or both, and the serpentine element is mechanically affixed to a source of compression or vibration or both.
