New Wearable Patch Monitors Fetal Health Continuously

A novel wearable ultrasound patch, named UPatch, has been created by scientists to provide continuous monitoring of fetuses during pregnancy. This proof-of-concept device aims to enhance early detection of potential complications, addressing drawbacks of current intermittent monitoring methods that often result in false alarms.

The UPatch continuously tracks fetal heart rate and blood flow, including real-time imaging of structures like the umbilical cord. Researchers addressed challenges such as signal loss due to fetal movement and weak signals from deep blood vessels, achieving results comparable to traditional handheld ultrasound devices.

Trials conducted in the US and UK with 62 pregnant participants demonstrated close agreement between UPatch and standard ultrasound measurements. In one significant case, the device identified severe intrauterine growth restriction in a pre-eclamptic pregnancy, leading to a timely caesarean delivery and preventing a stillbirth.

This technology offers a continuous data stream, allowing for personalized baseline analysis and pattern identification, which is crucial for timely interventions. The team is developing a wireless version, envisioning its use in daily life, including at home. They believe UPatch could be particularly beneficial in low-resource settings and offers significant potential for preventing stillbirths and advancing academic understanding of fetal development.
