Abstract:
A distributed wireless radio frequency-based charging system includes hardware and software platforms. The hardware platform includes adaptive energy harvesters and programmable energy transmitters. The software platform manages the hardware profiles, resources (e.g., energy waveforms and transmission powers), schedules the beams of the energy transmitters, and switches between modes of wireless charging and data access point. This allows the energy transmitters to be configured adaptively based on the ambient energy availability, energy needs and number of energy-requesting devices in the network. Under the software control, the energy transmitters can cooperatively form focused beams of energy and power for transmission to energy harvesters in the energy-receiving devices, such as sensors, Internet of Things (IoT) enabled appliances, and mobile/wearable equipment. The energy harvesters can utilize the energy contained within the transmitted beams, as well as ambient RF sources, for directly powering their operation or charging a battery/capacitor for subsequent use.
