ENERGY HARVESTER AND SELF POWERED WIRELESS SENSOR MODULE USING 2-WAY COMPRESSION LOAD

摘要

The present invention relates to a piezoelectric device comprising a case, a piezoelectric element accommodated in the case and having first and second surfaces respectively supported by inner surfaces of both sides of the case, and a piezoelectric element provided in the case so as to be relatively movable, And a vibration transmitting member for generating a bi-directional compressive load on the piezoelectric element by pressing the first and second surfaces of the piezoelectric element, respectively, by reciprocating linear motion according to the reciprocating linear motion, and a wireless sensor module using the same.
