The University of California San Diego researchers have made a giant leap forward in wireless ultrasound monitoring for subjects in motion, by developing the first fully integrated autonomous wearable ultrasound system for deep-tissue monitoring.
Traditional soft ultrasonic sensors all require tethering cables for data and power transmission, which largely constrains the user’s mobility. In contrast, the team's ultrasonic system-on-patch (USoP), can continuously measure central blood pressure, heart rate, cardiac output, and other physiological signals of users on the go, for up to twelve hours at a time.
“This project gives a complete solution to wearable ultrasound technology—not only the wearable sensor, but also the control electronics are made in wearable form factors,” said Muyang Lin, the first author of the study. “We made a truly wearable device that can sense deep-tissue vital signs wirelessly.”
According to the lab’s findings, the system...
