Abstract: A smart wearable device has a signal calibration function executed by a signal calibration method and applied to a finger, a limb and/or a neck of a user. The smart wearable device includes at least one physiological signal detector, at least one pressure detector and an operation processor. The at least one physiological signal detector is adapted to abut against a detection area of the user for detecting a physiological signal. The at least one pressure detector is disposed around the at least one physiological signal detector and adapted to detect a pressure value of the detection area. The operation processor is electrically connected with the at least one physiological signal detector and the at least one pressure detector. The operation processor is adapted to optimize the physiological signal when the pressure value exceeds a predefined pressure threshold.

Abstract: A wearable device and a method for performing a registration process in the wearable device are provided. The wearable device includes a light source, a light sensor and a microcontroller that performs the method. In the method, the light source is activated to emit a detection light and the light sensor senses a reflected light. A light intensity of the reflected light is calculated. A registration value is produced based on the light intensity. Specifically, the detection light with a specific frequency to be registered in the registration value is used as a reference to detect whether the wearable device is properly worn by a person. For example, since the wearable device can be worn on the person's wrist, the registration value is used to detect whether the wearable device is away from the wrist.

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.
