PIEZO-ELECTRIC ENERGY HARVESTER AND WIRELESS SWITCH INCLUDING THE SAME

摘要

According to an embodiment of the present invention, a wireless switch can transfer a communications signal to an external electronic device by using energy generated in a piezoelectric energy harvester as driving power. In addition, according to an embodiment of the present invention, the piezoelectric energy harvester can generate uniform energy by generating displacement in a piezoelectric element through magnetic force generated in a magnet.
