WIRELESS CHARGING SYSTEM FOR SMART GARMENTS SUPPORTING MULTIPLE CHARGING METHODS

Abstract:

A contactless charging system for smart garments having coils whose centroids are not colinear. Folding a coil in half through its centroid will null out its inductance. A smart garment having 3 coils that have centroids that are not colinear is proposed. Accordingly, there is no single folding line that intersects all 3 centroids thereby nullifying inductance. Power can be combined with one or more rectifiers such that power is not cancelled. The present disclosure is suitable for any charging environment or apparatus, such as, drawer or hanger.
