Wearable Ultrasound Patch Aims for Continuous Fetal Monitoring
Scientists have developed UPatch, a wearable abdominal ultrasound patch that can continuously monitor a fetus, autonomously image the womb, measure biometric parameters, and flag issues like preeclampsia; in tests with 62 pregnancies and 52 women over 1–6 hours, it performed on par with standard ultrasound and could broaden access to prenatal imaging, though it relies on a bulky backend and may be limited by movement; the study is published in Nature Biotechnology.
