The Pulse Detection System and Method Based on Electret Microphone
摘要
Abstract
In order to explore the relationship between sound signal produced by pulse vibration and standard pulse signal,pulse detection system which is based on electret microphone was designed to acquire radial artery pulse sig-nal of two channels. The conclusion pulse sound signal is significantly associated with the first derivative of standard pulse signal was got through the analysis of two signals. Meanwhile,a method for obtaining pulse signal by pulse sound signal was proposed. Pulse graph acquired according to this method has obvious pulse features and correlation coefficient is greater than 0.85,which proved that the method meets the requirements of objectification of pulse diag-nosis and can be used to acquire pulse wave.关键词
