Abstract

The present invention discloses a wearable device with combined sensing capabilities, which includes a wearable assembly and at least one multi-function sensor module. The wearable assembly is suitable to be worn on apart of a user's body. The wearable assembly includes at least one light-transmissible window. The multi-function sensor module is located inside the wearable assembly, for performing an image sensing function and an infrared temperature sensing function. The multi-function sensor module includes an image sensor module for sensing a physical or a biological feature of an object through the light-transmissible window by way of image sensing; and an infrared temperature sensor module for sensing temperature through the light-transmissible window by way of infrared temperature sensing.
