UC San Diego Jacobs School of Engineering researchers have developed a wireless wearable ultrasound patch that could be a game changer for real-time monitoring. This ultrasound fully integrated autonomous wearable ultrasonic system-on-patch (USoP) includes a small, flexible control circuit that communicates with an ultrasound transducer array to collect and transmit data wirelessly.
A machine learning component then interprets the data and track subjects in motion, thus enabling continuous tracking of physiological signals from tissues as deep as 164 mm. This means it is possible to continuously measure central blood pressure, heart rate, cardiac output, and other physiological signals for up to 12-hours at a time.

This technology has lots of potential to save and improve lives. The sensor can evaluate cardiovascular function in motion. Abnormal values of blood pressure and cardiac output, at rest or during exercise, are hallmarks of heart failure. For healthy populations, our device can measure cardiovascular responses to exercise in real time and thus provide insights into the actual workout intensity exerted by each person, which can guide the formulation of personalized training plans,” said Muyang Lin, a Ph.D. candidate in the Department of Nanoengineering at UC San Diego.
