摘　　要：目的:实现低负荷心冲击信号提取,方法:使用固体振动传感器提取心音信号,使用双向检波及低通滤波实现心音包络的提取,结果:与心电信号的同步对照显示该方法能够有效提取心冲击信号,结论:基于固体振动传感器的心音检测的技术能够有效提取心冲击信号,是低负荷心冲击信号提取的有效途径。Objective To detect the heart vibration signal non - instrusively. Method： A solid vibration sensor was used to detect the heart sound, then the heart sound envolope was formed with two way hardware rectification and low frequency passed filter. Result：h is an effective method to detect the heart vibration signal compared with simultaneous ECG recording. Conclusion：Heart vibration signal could be detected with the solid vibration sensor and it is an effective way to detect heart vibration signal non -instrusively.
