Abstract
Examples provide a piezoelectric energy harvester and a wireless switch including the same. The piezoelectric energy harvester includes a pressure transmission part situated between a pressing plate and a piezoelectric body, so as to transmit a uniform amount of pressure to the piezoelectric body, thereby generating a constant level of energy. In addition, a wireless switch uses energy generated in the piezoelectric energy harvester as its driving power, thereby transmitting radio frequency (RF) communications signals to an external electronic device to control the operation of the electronic device.
