New Ultrasound Patch Could Detect Heart Problems Early

University of California San Diego (UCSD) engineers have developed a smart skin patch that can detect blood clots and other concerning cardiovascular conditions. The soft patch uses ultrasound nanotechnology to provide a comprehensive picture of how blood flows through deep arteries and veins.

The new patch, worn on the neck or chest, continuously monitors blood flow, blood pressure, and heart function. It detects cardiovascular signals in blood vessels as deep as 14 centimeters (five and a half inches) inside the body in real-time with high accuracy. Analyzing those signals could help providers diagnose heart valve or circulation issues, as well as blockages that could cause strokes or heart attacks.

Improving on the limitations of existing wearables, the UCSD team embedded a phased array of ultrasound transducers within a stretchable polymer similar to a bandaid. A computer controls each individual 1-millimeter transducer separately. In one mode, the computer synchronizes all transducers to produce a high-intensity ultrasound beam that focuses deeply on a single spot. .." Lire la suite
