ABSTRACT:
A wristwatch with the function of sensing heart pulses having a watch housing on whose surface a liquid crystal display (LCD) is disposed. A voltage sensor is positioned within the watch housing for detecting the voltage frequency change during the blood circulation. The voltage sensor includes two electric terminals one of which is mounted on a bottom cover of the watch housing to permit a close contact with one hand wrist, and the other consists of two pieces of conductive rubber strips on the front surface of the insulated wristband for fingers of another hand to touch thereon. Both electric terminals are coupled by both hands while the detected voltage change frequency undergoes a static electric filtration by inductors and is transmitted to a filter shaping circuit for creating signals that are brought into a central processing unit to perform the processing and the calculating actions thereof. So, the processed result of the heart pulse rate is presented on the LCD.
