Abstract: A wearable electronic device with a function of detecting a wearing state, comprising: at least one electrode; a capacitance calculating circuit, coupled to the electrode, configured to calculate a capacitance variation generated by at least one of the electrode; and a wearing state determining circuit, coupled to the capacitance calculating circuit, configured to determine the wearing state according to the capacitance variation. By this way, the wearing state can be auto detected and the wearable electronic device can be correspondingly control according to the wearing state.

Abstract: A wearable device including a skin sensor and a processor is provided. The processor is configured to receive an authentication data for authenticating a user when a wearing state of the wearable device is adjacent to a skin surface of the user, execute a predetermined function in response to a request when the authentication data matches a pre-stored data and the skin sensor determines that the wearable device does not leave the skin surface after the authentication data is received, and reject or ignore the request when the skin sensor determines that the wearable device leaves the skin surface before the predetermined function is executed.
