Wearable acoustic sensors track fetal cardiac activity, skeletal development

Acoustic sensors are increasingly used in monitoring fetal health.

Imperial College’s Niamh Nowlan is using low cost, non-transmitting accelerometers and acoustic sensors to continuously track fetal movementto understand skeletal development. Acoustic sensors enable discrimination between the movement of the fetus and mother.

Israel’s Nuvo Groupis continuously monitoring fetal cardiac activity using acoustic sensors and ECG (to track both sound and electrical activity) in a wearable baby belt.
