ENERGY HARVESTER, PIEZOELECTRIC LAYER SEPARATION METHOD, AND PROPERTY ANALYSIS METHOD

摘要

According to an embodiment of the present invention, an energy harvester comprises: a cantilever having one end fixed to a fixing end and the other end, which may vibrate through external force; and a plurality of piezoelectric layers separately formed on one surface of the cantilever based on a curvature rate of the cantilever and generating electric energy through the vibration of the cantilever. The present invention provides an energy harvester capable of improving electricity generation efficiency by improving a structure of a piezoelectric layer.;COPYRIGHT KIPO 2016
