Abstract
A wearable apparatus configured to wirelessly receive charging power is provided. The apparatus comprises a band. The apparatus comprises a first receive coil wound in a clockwise direction along a first portion of the band as viewed from a direction normal to a cross section enclosed by the first receive coil. The apparatus comprises a second receive coil wound in a counterclockwise direction along a second portion of the band as viewed from the direction normal to the cross section. The apparatus comprises a parasitic coil overlapping a portion of the first receive coil and a portion of the second receive coil. The first receive coil is not electrically connectable to the second receive coil at distal ends of the band. The apparatus further comprises one or more resonant circuits comprising the first receive coil and the second receive coil.
