Abstract
Rich in human pulse of the heart, circulation and nerve both inside and outside the system, such as dynamic information. This paper presents a digital pulse of the specific method, the use of piezoelectric sensors have a pulse, after plastic surgery to enlarge, the importation of SCM within the corresponding control, which measured the pulse of one minute, beating number. Through observing the pulse signal, can check the health of the body, usually used for health centres and hospitals.
