1. A wireless power system, comprising:
a control system configured to output radio waves to an environment; and
a wearable device comprising:
an energy harvesting device configured to receive the radio waves and to harvest energy from the received radio waves;
a processor;
a sensor configured to detect a state of the wearable device and output a state signal associated with the detected state of the wearable device to the processor, wherein the processor is configured to output a device control signal based on the output state signal;
an indicator configured to activate a special effect based on the device control signal from the processor to provide an indication of the state of the wearable device; and
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, wherein at least the processor, the sensor, or the communicator receive power via the energy harvested by the energy harvesting device.
