Apparatuses and systems for wearable devices such as eyewear are described. According to one embodiment, the wearable device includes a frame, a temple, onboard electronics components, and a coupling mechanism. The frame is configured to hold one or more optical elements. The temple is connected to the frame at an articulated joint such that the temple is disposable between a collapsed condition and a wearable condition in which the device is wearable by a user to hold the one or more optical elements within user view. The onboard electronics components comprise at least a pair of electronics components carried by the frame and the temple respectively. The coupling mechanism is incorporated in the articulated joint and that is configured to electrically connect the pair of electronics components across the articulated joint both when the temple is in the wearable condition and when the temple is in the collapsed condition.
