Smart Electronic Stethoscope with Digital Filtering and Phonocardiogram (PCG)
Piezoelectric contact microphone amplifying faint heart murmurs with digital bandpass filters and live PCG wave visualization.
Project Overview
Upgrades traditional acoustic stethoscopes. A shielded piezoelectric contact chest piece captures low-frequency heart sounds (S1, S2, murmurs). Onboard digital IIR bandpass filters eliminate background speech and lung friction noise, streaming real-time Phonocardiogram waveforms over Bluetooth.
