Scientists have developed a wearable ultrasound patch that can continuously monitor fetal health through the mother’s abdomen.
The device, known as UPatch, is a soft, skin-mounted sensor designed to provide real-time monitoring throughout pregnancy. It was developed by researchers at Stanford University, working in collaboration with scientists from the University of Oxford and the University of California.
Real-time monitoring beyond traditional ultrasounds
Currently, fetal health is typically assessed during periodic ultrasound examinations that provide only brief snapshots of the baby’s condition. The new patch is designed to enable longer-term, continuous monitoring, even when the fetus is moving.
The device tracks blood flow and may help identify potentially dangerous changes earlier than conventional screening methods, giving physicians more time to intervene when necessary.
Clinical testing shows promising results
The technology was tested on 62 pregnant women. According to the researchers, the patch’s measurements closely matched those obtained through standard ultrasound examinations.
The team subsequently evaluated the device in an additional group of 52 women with high-risk pregnancies, including patients diagnosed with preeclampsia and gestational diabetes.
In one case, the patch helped detect signs of worsening fetal health in a patient with severe preeclampsia. The early warning enabled physicians to make a rapid clinical decision and perform a cesarean delivery, potentially preventing fetal death.
Potential benefits for underserved regions
Researchers say the technology could be especially valuable in areas with limited access to ultrasound specialists and advanced medical equipment.
If further studies confirm its effectiveness, the device could improve prenatal care by enabling more frequent monitoring outside traditional clinical settings. It may also provide expectant mothers with greater peace of mind by offering continuous insight into their baby’s well-being throughout pregnancy.
