MIT's Wearable Ultrasound Patch Paces the Heart Without Surgery
TL;DR
MIT researchers have created a chest-worn hydrogel patch that noninvasively paces the heart by enabling engineered heart cells to respond to ultrasound via a gene-therapy primer—a technique called sonogenetics. In tests on rats and pig hearts, the patch restored steady rhythms during daily activity, pointing toward a potential noninvasive alternative to implanted pacemakers and, with future closed‑loop sensing, a fully automated pacing system.
