Abstract
Devices to be charged and wireless charging devices are disclosed. A DTBC includes a processing unit, a battery, an axially wound receiver coil and battery charging components. The battery powers the processing unit. The axially wound receiver coil has a first end and a second end located at opposite ends of a central axis of the axially wound receiver coil and receives electromagnetic flux via either one of the first end or the second end. The battery charging components are coupled between the battery and the axially wound receiver coil, convert the electromagnetic flux into direct current (DC) and apply the DC to charge the battery.
