Created by a team of researchers led by Northwestern University and The University of North Carolina at Chapel Hill, this device consists of a wireless sensor capable of measuring the mother’s and baby’s vital signs and providing new data such as the mother’s physical movements and laboring positions. This device can transfer this data to the physicians’ smartphone or tablet, opening new possibilities for remote pregnancy monitoring.

Three flexible, soft, and low-profile sensors provide comprehensive vital sign monitoring for both women and fetuses, including advanced parameters like continuous cuffless blood pressure, electrohysterography-derived uterine tracking, and automated body position classification, all with time-synchronized operation. The system’s performance, usefulness, and safety have been demonstrated in field trials of pregnant women between 25 and 41 weeks of pregnancy in any context.
