Scientists have developed an ultrasonic adhesive called UPatch, capable of continuously monitoring the baby inside the uterus in real-time. This flexible device, placed on the abdomen of the pregnant woman, uses Doppler ultrasound to capture images and measure fetal blood flow. The goal is to offer continuous and more autonomous monitoring, especially in cases of high-risk pregnancies. The UPatch successfully recorded fetal and umbilical cord blood flow for several hours in a row, even with the movement of the mother and baby.
Development and Challenges
The development of UPatch faced challenges, such as creating a technology capable of functioning during the constant movements of the baby and umbilical cord. To solve this, researchers created automatic tracking algorithms that identify and track fetal blood vessels throughout the examination. In a study published in the journal Nature Biotechnology, the results obtained by UPatch presented “good agreement” with equipment already used in medical practice. The device also managed to capture fetal anatomical structures used in obstetric evaluations, including measurements related to the baby’s growth. In 52 pregnant women, including cases of pre-eclampsia, gestational hypertension, fetal growth restriction, and gestational diabetes, continuous monitoring allowed observing dynamic changes in fetal blood flow over time.
Care and Limitations
However, it is important to consider the care and limitations of UPatch. Like any medical technology, its use must be evaluated and supervised by qualified health professionals. The safety and effectiveness of the device depend on correct application and interpretation of results. Furthermore, UPatch is still in the validation phase, and more studies are necessary to confirm its clinical utility. Researchers emphasize that the device aims to complement, not replace, current monitoring methods. Fetal blood flow and umbilical cord are critical aspects to be monitored during pregnancy, and UPatch offers a new tool for this.
In cases of high-risk pregnancies, continuous monitoring can be especially valuable. For example, in cases of pre-eclampsia, UPatch can help detect changes in fetal blood flow that indicate the need for medical intervention. Although UPatch is a promising innovation, its clinical use still depends on further research and evaluations.
