WIRELESS POWER SYSTEMS AND METHODS SUITABLE FOR CHARGING WEARABLE ELECTRONIC DEVICES

摘要

Base units, systems and methods for wireless energy transfer are described. A wireless energy transfer system according to some examples includes a transmitter of wireless energy and a distance separated receiver. Examples of transmitter and receiver coils are described. Examples of distance and orientation optimization are described. Examples of wireless charging systems that may be include helmets, body worn units, and/or light sockets are described.

1. A system comprising:
a transmitter having a transmitter coil configured for wireless power delivery, the transmitter having a transmitter impedance; and a receiver, separated from the transmitter by a distance, the receiver having a receiver coil configured for receipt of wireless power from the transmitter, the receiver coil comprising a magnetic metal core within a wire winding, the receiver having a receiver impedance; wherein the transmitter and receiver are loosely coupled, and wherein the transmitter impedance and the receiver impedance are optimally matched for a particular distance separation between the transmitter and the receiver, and non-optimized for all other separation distances.
