MEMS Microphone Heart Sound Analysis: Engineering a Digital Stethoscope from Sensor to Signal
Why MEMS Microphones Are Reshaping Digital Auscultation Traditional electronic stethoscopes rely on piezoelectric transducers or electret condenser microphones. MEMS microphones offer OEMs three decisive advantages for cardiac acoustic sensing: The trade-off is that MEMS microphones are designed for airborne acoustic pickup, not contact sensing against human tissue. Capturing clinically usable heart sounds — S1, S2, and the diagnostically critical murmurs …
