Passive Acoustic Fetal Heart Rate Monitor for Non-Invasive At-Home Use
Abstract: This paper presents the design and development of a passive acoustic sensor array to enable at-home fetal heart rate monitoring without the need for active ultrasound emissions or battery power. The device provides a safe, convenient and non-invasive alternative to current Doppler-based solutions. An array of MEMS microphones and advanced beamforming and noise cancellation algorithms allow the system to passively detect fetal heart sounds. Preliminary testing demonstrates the ability to reliably measure fetal heart rate between 120-160 beats per minute from the second trimester onwards. This low-cost, easy-to-use device could improve access to regular fetal monitoring, especially in low-resource settings.
