Wearable Loops with Embedded Circuitry

Abstract

An electronic device such as a loop-shaped wearable electronic device may have a fabric cord with first and second opposing ends and a housing unit coupled between the first and second ends. The housing unit may contain circuitry such as a visual output region, sensors, communications circuitry, and wireless power receiving circuitry. The wearable electronic device may include haptic output devices for providing haptic output for a user or for changing the shape of the fabric cord. The fabric cord may include a conductive strand that forms a coil for receiving wireless power signals from a wireless power transmitter. The wearable electronic device may be stored in a charging case that includes wireless power transmitting circuitry for powering the wearable electronic device. Control circuitry in the charging case may change an opacity of the charging case based on a charging status of the wearable electronic device.
