Abstract:
1. A watch-typed heartbeat sensing device for detecting at least one heartbeat signal of a user, comprising: a casing having an internal hollow space a first end, and a second end; a watch band with two ends respectively connected to the first end and the second end of the casing; a circuit board mounted in the hollow space of the casing, the circuit including a first contact, a second contact, a third contact, a fourth contact and a control circuit, the control circuit including: a first pair of conductors mounted at the first end of the casing, the first pair of conductors including an inner plate and an outer plate respectively electrically connected to the first contact and the second contact of the circuit board; and a second pair of conductors mounted at the second end of the casing, the second pair of conductors including an inner plate and an outer plate and respectively electrically connected to the third contact and the fourth contact of the circuit board; wherein when the casing is put on a wrist of one hand of the user by means of the watch band, the inner plate of the first pair of conductors and the inner plate of the second pair of conductors contact the wrist of the user, and when the user puts his other hand onto the casing of the heartbeat sensing device and contacts the outer plate of the first pair of conductors and the outer plate of the second pair of conductors, thereby two pairs of heartbeat signals are generated respectively at the first pair of conductors and the second pair of conductors and transmitted to the control circuit of the circuit board.
