A wireless power system includes a control system configured to output radio waves to an environment and a wearable device having an energy harvesting device configured to receive the radio waves and to harvest energy from the received radio waves. The wearable device also includes a processor and a sensor configured to detect a state of the wearable device and output a state signal to the processor. The processor is configured to output a device control signal based on the detected state signal. The wearable device further includes a communicator configured to receive the device control signal from the processor and to provide an output to the control system based on the state of the wearable device. At least the processor, the sensor, or the communicator receive power via the energy harvested by the energy harvesting device.
