SYSTEMS, METHODS, AND DEVICES FOR OPTICAL WIRELESS CHARGING
First Claim
1. An optical charger for wirelessly charging a chargeable device, comprising:
- a light source configured to provide light to the chargeable device sufficient to charge or power the chargeable device, the light spectrally matched to a bandgap of an optical receiver positioned on the chargeable device;
an optical casing at least partially surrounding the light source; and
an elastomer situated on the optical casing, the elastomer located between the optical casing and the chargeable device when charging.

Abstract
A system and method for wirelessly charging a chargeable device is provided. In one aspect, the method includes detecting a presence of a chargeable device within a charging region of the optical charger. The method further includes providing light to the chargeable device upon detecting the presence of the chargeable device within the charging region. The light provided through an optical casing and an elastomer when the chargeable device is in contact with the elastomer. The optical casing optically coupled to the elastomer. The light sufficient to charge or power the chargeable device and spectrally matched to a bandgap of an optical receiver positioned on the chargeable device.
