Abstract:
A charging method using an electrode of a biometric sensor, and an electronic device using the same. A wearable electronic device includes a housing, at least one electrode exposed outwards from one surface of the housing, a battery provided inside the housing, a charger circuit connected electrically to the battery, at least one sensor, a switch configured to connect the charger circuit or the at least one sensor to the at least one electrode, and a processor connected electrically to the charger circuit, the at least one sensor, and the switch. The processor is configured to determine whether the wearable electronic device is coupled to a body, based on a signal acquired through the at least one sensor, and control the switch to connect the charger circuit or the at least one sensor to the at least one electrode in correspondence with a result of the determination.
