POWER GENERATION APPARATUS USING PIEZOELECTRIC ELEMENT STACKED BY MULTILAYER STRUCTURE

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generating device using a piezoelectric element stacked in a multi-layered structure, which is constructed so that a cantilever assembly including a piezoelectric element and a cantilever is stacked in multiple layers to increase power generation efficiency against space. A plurality of cantilevers which are fixed to the upper and lower ends of the upper cantilever and fixed to the upper and lower cantilevers and are disposed between the upper and lower cantilevers, A piezoelectric vibrator connected to the other end of the cantilever and having a constant weight, a bonding material for coupling the piezoelectric element and the cantilever, a piezoelectric element attached to the upper surface of the upper cantilever, and a piezoelectric element attached to a lower surface of the lower cantilever, Comprising a coating of a thermoplastic material formed, The cantilever is vibrated and the piezoelectric element is configured to generate a current by the vibration of the cantilever in the up and down direction so that the cantilever assembly including the piezoelectric element and the cantilever is stacked in multiple layers to increase the space-A power generating device using a piezoelectric element laminated in a multilayer structure is provided.;
