  Abstract

In this paper, we design and implement a low-power RF energy harvesting circuit that is essential for the extended operational lifetime of wireless sensor networks and verify its operation. The proposed energy harvesting circuit consists of a rectifier circuit which converts high frequency AC input power to DC charging power and a low-power DC-DC boost charging chipset which employs a nano-power boost charger and a buck converter integrated circuit. The rectifier circuit is based on a 90 MHz RF input power and provides voltage amplification to ensure the output voltage of rectifier circuit for the charging circuit operation. The charging circuit employs a chipset suitable for a low power environment and stores energy by using a supercapacitor considering a low temperature environment.
