Engineers at the University of California San Diego developed a soft and stretchy ultrasound patch that can be worn on the skin to monitor blood flow through major arteries and veins deep inside a person’s body.
Knowing how fast and how much blood flows through a patient’s blood vessels is important because it can help clinicians diagnose various cardiovascular conditions, including blood clots; heart valve problems; poor circulation in the limbs; or blockages in the arteries that could lead to strokes or heart attacks.
The new ultrasound patch developed at UC San Diego can continuously monitor blood flow—as well as blood pressure and heart function—in real time. Wearing such a device could make it easier to identify cardiovascular problems early on.
A team led by Sheng Xu, a professor of nanoengineering at the UC San Diego Jacobs School of Engineering, reported the patch in a paper published July 16 in Nature Biomedical Engineering.
The patch can be worn on the neck or chest. What’s special about the patch is that it can sense and measure cardiovascular signals as deep as 14 centimeters inside the body in a non-invasive manner. And it can do so with high accuracy.
“This type of wearable device can give you a more comprehensive, more accurate picture of what’s going on in deep tissues and critical organs like the heart and the brain, all from the surface of the skin,” said Xu.

Your blog has had a name change! I’ve wondered from time to time how the other guy you started this all off with has fared over the years. He bowed out over a twinky if I remember right? Always interesting, Tony. Cheers, Vinny 🙂

LOL You have a good memory, Vinny. After a 30 year friendship, culminating in this blog, we parted ways. I have not seen or heard from or of him since.
