Energy harvesting systems and methods

Abstract

A system and method for harvesting radio frequency energy for powering devices includes one or more antennas tuned to receive radio frequency signals from different sources and an energy harvester configured to derive energy from the radio frequency signals and provide power to a power consuming device. A power integrator can store the energy until it is needed by the power consuming device. The energy harvester can extract data from one or more of the radio frequency signals and transmit the data to the power consuming device. The power consuming device can change an operational mode based on the amount of power received or the data received from the energy harvester. The power consuming device can transmit data to one of the sources to increase radio frequency signal transmissions to increase the amount of energy harvested by the energy harvester and delivered to the power consuming device.
