Abstract

A wearable device, such as an earphone, may include a conductive coil which may be used in several modes, including a first mode for harvesting power for charging an internal battery, a second mode for communicating via near field communications (NFC), and a third mode for communicating via near field magnetic induction (NFMI). Additionally, the wearable device may include a controller, configured to adapt or configure the conductive coil for each of the operational modes.
