Abstract

This research presents a PEH/RF transmitter for internet of thing applications using an ultra-high power density energy harvester. A novel designing mechanism for actuating a bimorph PZT piezoelectric generated over than 60 mW power for one pressing process was proposed. The fabricated harvester consist of NVC, switch inductor circuit, and dc-dc circuit can provide outputs more than 16.2 mW, that it was the power consumption of commercial RFIC transmitters. At last, the signal represent the connecting processing form PEH/RF transmitter was succeed to be detected by receiver with the intensity of -28.44 dBm.
