Abstract:
A piezoelectric energy harvester includes a thin film member, a support member situated to support the center or an edge of the thin film member, a piezoelectric member situated on the thin film member, and a driving member situated on the thin film member, situated to be misaligned with the support member, and configured to press the edge or the center of the thin film member. Such a design provides improved durability and functionality for a piezoelectric
Abstract:
A wireless switch includes a first energy harvester including a circuit, and a second energy harvester configured to open or close the circuit of the first energy harvester unit by an external operation. Hence, by using this approach, the wireless switch is able to operate without a requirement for providing a separate power supply.
