Abstract

This paper presents a measurement of heart signal and analyzes to educe heart rate based on the pressure sensor. The heart pumps out blood and causes the vibration of body and the objects contacted with the body. The pressure sensor transforms the vibration into electrical signals. The electrical signals are put into filters, amplifiers, and other signal processing circuits. Then the output is analyzed by wavelet and improved mode maximum value algorithm to educe the heart rate. Compared with a single channel simultaneously recording electrocardiograph (ECG), the experiment results show that the educed heart is basically the same as the simultaneous recording ECG.
