Abstract

A receiver coil part is applied to an open-ring or close-ring carrier part of a wearable device. The receiver coil part includes a contiguous conductive wire. The contiguous conductive wire can generate an induced current. Moreover, some of the conductive segments of the receiver coil part are selectively coated, covered or enclosed by a magnetic structure. Consequently, the magnetic field lines generated by the conductive segments are shielded by the magnetic structure. Moreover, the wearable device with the receiver coil part can be placed on a charging pad more flexibly.
