A new wireless patch can provide real-time information on tissue stiffness

The patch uses sound waves to assess muscle and tissue under a person’s skin

The patch might be incorporated into sports wear or used to help diagnose cancer, researchers said

THURSDAY, Sept. 18, 2025 (HealthDay News) — An experimental wireless patch might help injured athletes better recover from muscle tears, sprains and strains, according to a new study.

The patch measures tissue stiffness by sending sound waves along the surface of the body and listening to the resulting vibrations, researchers said recently in the journal Science Advances .
