Abstract
Apparatuses and systems for wearable devices such as eyewear are described. According to one embodiment, the wearable device includes a frame, onboard electronics components, and an antenna disposed around an eyepiece area of the frame that is configured to hold an optical element. The antenna is configured for inductive coupling. In some embodiments, a switch coupled to the antenna allows selection between circuitry for inductive charging of a battery and near-field communication (NFC) circuitry for communicating data via the antenna.
