Abstract
Provided are a piezoelectric energy harvester and a wireless switch including a piezoelectric energy harvester. The piezoelectric energy harvester uses energy generated in the piezoelectric energy harvester as driving power, thereby transmitting communications signals to an external lighting device using this driving power. Furthermore, the piezoelectric energy harvester generates power having different magnitudes depending on magnitudes of external force applied to a pressing member by a user or duration of the external force. A transmitting module of the wireless switch transmits signals that may adjust intensity of light to the external lighting device depending on the magnitudes of the generated power.
