PIEZOELECTRIC ENERGY HARVESTER AND WIRELESS SWITCH INCLUDING THE SAME

摘要

The present invention provides a piezoelectric energy harvester which provides driving power to a wireless transmission module provided in a wireless switch, and increases durability by minimizing an impact while driving. According to an embodiment of the present invention, the piezoelectric energy harvester comprises: a thin film member; a support member arranged to support the center or the edge of the thin film member; a piezoelectric member arranged in the thin film member; and a driving member formed in the thin film member, arranged to be misaligned with the support member, and formed to push the edge or the center of the thin film member.
