Abstract: A keyboard device having functionality of physiological parameter measurement is disclosed, which comprises a keyboard main body and at least two physiological signal sensing units. The physiological signal sensing unit comprises a lighting element and a light sensing element. Moreover, the physiological signal sensing unit further comprises a touch plane that is exposed out of the surface of the keyboard main body. When a user is typing the button keys of the keyboard main body, the user can touch the touch plane by one finger thereof, such that the physiological parameter calculating unit receives an optical signal through the physiological signal sensing unit, thereby calculating physiological parameters of the user after applying a physiological parameter calculating process to the optical signal. The calculated physiological parameter comprises heartbeat and heart rate.
