1. A resonant wireless power receiver comprising:
- an electromagnetic resonator that includes one or more inductive elements that are arranged to form a receiver coil and a network of passive components arranged to form a matching network;
a rectifier circuit that converts ac power from the electromagnetic resonator to dc power; and
an available-power indicator that measures the rectified power to assess the instantaneous power available to the receiver.

Abstract
A resonant wireless power receiver that includes an electromagnetic resonator having one or more inductive elements that are arranged to form a receiver coil and a network of passive components arranged to form a matching network. A rectifier circuit converts ac power from the electromagnetic resonator to dc power. An available-power indicator measures the rectified power to assess the instantaneous power available to the receiver.
