More effectively measuring tissue stiffness could help treat cancer, sports injuries and more. A team of engineers at the University of California San Diego has developed a stretchable ultrasonic array capable of serial, non-invasive, 3D imaging of tissues as deep as four centimeters below the surface of human skin, at a spatial resolution of 0.5 millimeters. This new method provides a non-invasive, longer-term alternative to current methods, with improved penetration depth.

The research emerges from the lab of Sheng Xu, a pro...
