Systems, methods, and devices for using a battery as an antenna for receiving wirelessly delivered power from radio frequency power waves

This invention describes a wireless power receiver that cleverly uses a battery itself as an antenna to pick up radio frequency (RF) power signals. Specialized power conversion circuitry then takes these signals and turns them into direct current (DC) voltage to charge the battery. The claims specifically detail connecting the battery terminals to the power conversion circuitry and using capacitors in these connections, with an option for additional charging circuitry to power an embedded electronic device.

Why it matters: Filed before advancements in compact, efficient RF power conversion and battery integration. This could improve system performance and feasibility now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedRF antenna design, power conversion circuitry, battery integration
