Abstract
Embodiments of the disclosure can provide an optical charging system with an integrated sensor and power receiver. An electronic device (e.g., a wearable) can include an optical sensor for performing photometric measurements. A photodiode of the sensor can be shared and used for generating an electrical signal when exposed to a light source (e.g., LED) of a light power transmitter. The electrical signal can be conditioned by a power management circuit and can be used to charge a device battery. The light power transmitter can include a photodiode, which can be used for establishing a connection with the device using an optical signal emitted by a light source of the optical sensor. The light power transmitter can be power by, e.g., a USB connection. The intensity of the power transmitter light source can be regulated via a feedback signal from the device, based on the battery charging status.
