Wireless energy harvesting systems for low-power electronic sensors

Payam Nayeri | pnayeri@mines.edu

Wireless energy harvesting systems are capable of receiving RF signals and using the energy within the signal to power low-power electronics. This research aims to develop an RF energy harvesting system capable of harvesting broadband ambient RF from local FM radio stations (88-108 MHz) to supply energy to low-power sensors. This will be accomplished by implementing a receiving antenna, broadband matching networks, multiple types of rectifier circuits, and a power management unit that will manage the power supplied by the harvester and deliver the necessary power to the low-power sensor. In order to minimize power loss we will use Schottky diodes with a very low forward voltage to build the rectifier. The matching networks will comprise of through hole capacitors and inductors.
