Researchers from the University of California, San Diego have created a patch for patients with lung and heart diseases, as well as, critical diseases and or undergoing surgeries. Ultrasound technology allows the patch to track physiological and other vital signs, at a much earlier stage and more accurately.
"Wearable devices have so far been limited to sensing signals either on the surface of the skin or directly below it. But it's like seeing only the tip of the iceberg. By integrating ultrasound technology into wearable materials, we can receive many other signals, biological events and actions that occur "under the skin" without the need for punctures," said Sheng Xu, Professor of nano-engineering at the UC San Diego Jacobs School of Engineering.
