Detection on the Pulse Signal of Human Body Based on Piezoelectric Impedance Technique

Abstract:

Pulse wave is one of important physiological characters of human body. Detection on pulse sign is helpful for health care and treatment of disease. In order to detect the change of pulse signal of human body, the work principle of detection based on the piezoelectric impedance technique was presented and a new piezoelectric impedance sensor was designed. With an experiment platform set up, detection experiments of pulse signal were created. Two methods were used to deal with the experimental data. Results from a series of experiments intuitively show that with pressure applied to human body bigger and bigger, the pressure index increases gradually. It illustrates that the change of pulse signal is bigger and bigger. The result indicates that this method has good sensitivity and provides a new detection method. The experiment shows that the piezoelectric impedance technique is feasible to detect the change of pulse sign.
