Fish-inspired sensor tracks how human heart tissue responds to disease and treatment

Engineers have developed a new way to monitor how tiny lab-grown human heart tissues beat—by effectively "listening" to the ripples they create.

The team has created a wireless, noninvasive sensing platform that can biomechanically measure how strongly the miniature heart tissues, known as cardiac organoids, beat in real time.

The research could help accelerate drug development, improve disease modeling and reduce reliance on animal testing, offering a more human-relevant way to study how the heart works. ...
