Wearable ultrasound patch can monitor high-risk pregnancies | Latest Tech News
A new being pregnant patch might present essential, 24-hour monitoring for high-risk mothers.
For a long time, ultrasounds have been the first means of fetal monitoring, but now engineers at UC San Diego have designed a wearable patch that guarantees steady, complete insight into the health of mother and child.
The versatile, adhesive-backed UPatch is utilized to the lady’s stomach to ship up-to-the-minute data about blood stream in the fetus and umbilical wire. Roughly the dimensions of a hand, the UPatch is linked to a laptop that analyzes ultrasound data.

Published this week in Nature Biotechnology, medical testing of the UPatch demonstrated its life-saving potential. In one case, the patch recognized a extreme placental dysfunction that led to an early Cesarean supply, which researchers say might have saved the infant’s life.
“Wearable ultrasound technology has the potential to enable continuous prenatal monitoring and improve pregnancy outcomes in ways that were previously not possible,” said research co-first writer Geonho (Tom) Park, a chemical and nanoengineering Ph.D. pupil at the UCSD Jacobs School of Engineering.
Park and his staff collected monitoring data across 62 pregnancies — some have been healthy, while others have been thought of high risk on account of gestational diabetes, preeclampsia, high blood pressure or irregular fetal growth.
The UCSD researchers in contrast their findings to those from a normal ultrasound machine — the patch and the machine produced statistically equal outcomes.
Further, while current ultrasound technology requires skilled sonographers and gives only a snapshot of fetal health, the UPatch tracks fetal health repeatedly without a handbook technician.

“To comprehensively monitor mothers and babies over the amount of time needed to catch complications like preeclampsia, you need a system that can work continuously and largely on its own,” said co-first writer Yizhou Bian.
“That is why the sensing depth, functional capabilities and autonomy of this ultrasound technology are critical.”
Developing the patch posed important challenges, as it required amassing and deciphering data from deep inside the uterus and offering imagery in a consistently fluctuating surroundings.
“We thought, ‘What if we target the ultrasound device onto the placenta, in the area where the umbilical cord attaches?’” Park said. “Even though everything is moving, there is some stability in the umbilical cord at that location.”
A key ingredient of the design is an image segmentation algorithm that tracks the placenta-anchored end of the umbilical wire, enabling the machine to present constant measurements despite modifications in the positions of the mom and fetus.
Researchers are hopeful this technology might help medical doctors handle high-risk pregnancies and detect problems earlier. While they imagine the patch shall be used in hospital settings at the outset, they plan to develop a wi-fi model that would enable medical doctors to monitor sufferers when they’re at home.
The technology might also show useful in low-resource settings where ultrasound technicians and long-term monitoring usually are not available.
