A measuring unit has at least one first signal-measuring end and at least one second signal-measuring end. The first signal-measuring end and the second signal-measuring end contact at least two symmetrical portions of a living being to obtain at least one first pulse signal and at least one second pulse signal of the two symmetrical portions, respectively. A signal-analyzing unit is coupled to the measuring unit. The signal-analyzing unit obtains at least one physiological data based on the first pulse signal and the second pulse signal, respectively, further to determine a physiological condition of the living being according to the physiological data.
