“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, a Ph.D. candidate in the Department of Nanoengineering at UC San Diego and the first author on the study. “We made a truly wearable device that can sense deep tissue vital signs wirelessly.”
“This technology has lots of potential to save and improve lives,” Lin said. “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.
Thanks to technological advances and the hard work of clinicians over the last few decades, ultrasound has received an ongoing wave of interest, and the Xu lab is often mentioned in the first breath as an early and enduring leader in the field, particularly in wearable ultrasound. While developing its latest innovation, the team was surprised to discover that it had more capabilities than initially anticipated.
However, when the algorithm is trained using one subject’s data, that learning may not be transferable to other subjects, making the results inconsistent and unreliable.
