Patent attributes
Systems, methods, and devices for using an existing components of a battery as an antenna for receiving wirelessly delivered power from radio frequency power waves are provided. A wireless power receiver includes a first connection with a battery. The first connection is configured to receive an alternating current that is generated by reception of wirelessly delivered radio frequency (RF) power signals. The RF power signals are received by at least a part of the battery that is acting as an antenna. The wireless power receiver further includes power conversion circuitry that is electrically coupled to the first connection with the battery. The power conversion circuitry is configured to convert the alternating current into a direct current (DC) voltage that is used to charge the battery.
