PIEZOELECTRIC GENERATOR USING LAYERED STRUCTURE

摘要

PURPOSE: A piezoelectric element generator is provided to improve area efficiency and power generation efficiency by installing a number of piezoelectric generator in the same surface area by using a layer structure. CONSTITUTION: A first system(100) forms a first input protrusion(110) in one side. The first system is vertically vibrated from an external impact. The first system comprises a first mass part(120) which receives the external impact. A second system(200) forms a second input protrusion(210) in order to receive potential energy stored by the vertical elastic oscillation. A piezoelectric element(230) in the second system is arranged to be a layer structure.
