Title:
THREE-DIMENSIONAL WIRELESS CHARGING COIL
Document Type and Number:
WIPO Patent Application WO/2015/191203
Kind Code:
A8
Abstract:
Wearable devices are described herein that include a housing, a magnetic shielding, and a coil. The housing includes a first outer surface, a second outer surface opposite the first outer surface, the second outer surface being narrower than the first outer surface and being configured to contact skin at an external body surface, and a chamfer of a given shape between the first outer surface and the second outer surface. The magnetic shielding is disposed in the housing between the first and second outer surfaces. The coil is disposed in the housing and configured to receive energy via a magnetic field. The coil includes coil windings that substantially fit the shape of the chamfer, where the coil windings include a first portion of windings proximate to the magnetic shielding and further include a second portion of windings narrower than the first portion and proximate to the second outer surface.
