PIEZOELECTRIC ELECTRIC GENERATOR

摘要

PURPOSE: A piezoelectric generator is provided to maximize an occupied volume of a piezoelectric material in the same space by arranging a plurality of cantilevers in a circular space or a rectangular space. CONSTITUTION: A through-hole and two or more slits(34) are formed at an elastic substrate. One or more cantilevers(38) are formed by the through-hole and the slits of the elastic substrate. A piezoelectric layer is formed on the cantilevers. The elastic substrate is formed with a shape of a polygon or a shape of a circle. The raw material of the elastic substrate is composed of one of polymer, aluminum, copper, brass, stainless, and steel.
