Abstract
An apparatus, system, and method directed to the charging of electronic devices, and in particular to the wireless charging of battery enabled devices using FM band signals
Claims18
An apparatus for providing power to an electrical device, the power scavenged from ambient radio frequency energy, the apparatus comprising:
- at least one antenna element, disposed in a loop or in a portion of a loop;
- a detector, coupled to the antenna, for detecting radio frequency energy in a Frequency Modulation (FM) broadcast band;
- a rectifier, coupled to the detector, for providing a direct current output;
- and
- a battery, coupled to be charged by the rectifier.
2 more elements
A method for scavenging power from one or more Frequency Modulation (FM) broadcast band signals, the method comprising:
- receiving, via at least one antenna element having a loop shape or a portion of a loop shape, a received radio signal;
- detecting the received radio signal;
- generating a direct current output from the received radio signal;
- and
- charging an energy storage device by using the direct current output.
