GAPS BETWEEN TRANSMITTERS AND RECEIVERS IN WIRELESS POWER SYSTEMS AND RELATED SYSTEMS, METHODS, AND DEVICES

Gaps between transmitters and receivers in wireless power systems and related systems, methods, and devices are disclosed. A housing includes an internal surface configured to face a receive power coil and an external surface configured to face a wireless power transmitter. The external surface is shaped to define one or more gaps between the external surface and a surface of the wireless power transmitter responsive to placement of the external surface into engagement with the surface of the wireless power transmitter. An electronic device includes a receive power coil and a barrier including an internal surface facing the receive power coil and an external surface configured to face a transmit power coil. The external surface defines a gap between the external surface and a surface of the wireless power transmitter responsive to placement of the external surface in engagement with the surface of the wireless power transmitter.
