Interesting to see how this can be applied to cardiology in the future. 

“Engineers at the University of California San Diego have developed a wearable ultrasound tech device that can provide long-term, wireless monitoring of muscle activity with potential applications in healthcare and human-machine interfaces. Designed to stick to the skin with a layer of adhesive and powered by a battery, the wearable ultrasound tech device enables high-resolution tracking of muscle function without invasive procedures.”
