A shielded PVDF Film sensor has been used to obtain the Phonocardiogram (PCG) with high Signal-to-Noise Ratio (SNR). A very simple circuit is good enough to detect the first (S1) and the second (S2) sound of the PCG without using any digital signal processing technique. The mechanical coupling betwe...
