Key result

Raspberry Pi-based wireless digital stethoscope successfully captures and transmits heart sounds for remote telemedicine.

Key Points

To design an accessible, low-cost wireless digital stethoscope that allows healthcare workers to monitor heart sounds remotely and maintain social distancing during infectious disease outbreaks.
Interfaced an acoustic stethoscope head with a condenser microphone to capture acoustic cardiac sounds.
Processed signals using a Raspberry Pi with 24-bit pulse coded modulation (PCM), Nyquist-criterion sampling, and Python scripts for digital filtering and 6db amplification before saving files in .wav format.
Established wireless data transmission via a web platform and email to enable remote auscultation on smartphones and computers.
Constructed a prototype capable of amplifying recorded physiological audio by 6db with customizable gain settings.
Demonstrated remote transmission of digitized cardiac recordings, allowing clinicians to auscultate through smartphone speakers or Bluetooth devices without direct patient contact.
