| Abstract: | 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:It 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. |
