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: An optical detection device is applied to an organism and includes a light emitting module, an optical detection module and an operation processor. The light emitting module includes a plurality of light emitters arranged along a first direction. The optical detection module includes a plurality of optical sensors arranged along a second direction and symmetrically relative to the light emitting module. The second direction is substantially different from the first direction. The optical sensors are substantially placed more outward from a center of the optical detection device than the light emitters. The operation processor is electrically connected to the optical detection module. The operation processor is adapted to analyze signal variation in the plurality of light emitters acquired by each of the plurality of optical sensors for determining a physiological feature of the organism.
