RF Energy Harvesting by a Network Node

摘要

Disclosed are various embodiments for energy harvesting by circuitry of a node in a network. The node operates in a communication mode that includes communicating, via an RF transceiver, data with another node in the network. The node includes an energy storage device that provides power for the node. The node switches, via an RF switch, from said communication mode to an energy harvest mode. The energy harvest mode includes receiving RF emissions accessible to the node via an antenna. The RF emissions are converted to DC electrical energy, and the DC energy is stored in the energy storage device.

1. A method for energy harvesting by circuitry of a node in a network, comprising:
operating in a communication mode comprising:
communicating, via a radio frequency (RF) transceiver, data with another node in the network, wherein the node comprises an energy storage device that provides power for the node; and switching, via an RF switch in the node, from said communication mode to an energy harvest mode comprising:
receiving RF emissions accessible to the node via an antenna;providing the received RF emissions to a rectifier;converting the RF emissions to direct current (DC) energy; andstoring the DC energy in the energy storage device.
