MIT Engineers Develop Postage-Stamp Ultrasound Pacemaker, Correcting Arrhythmias in Rats
3 articles · Updated · MIT News · Jun 2
A postage-stamp-sized chest sticker delivered ultrasound pulses that quickly corrected arrhythmias and restored regular heart contractions in rats, MIT engineers reported in Nature Biomedical Engineering.
The system works by pairing the wearable with sonogenetics: engineered heart cells open ultrasound-sensitive ion channels, let in calcium, and beat in sync with the pulses.
Lab tests showed the approach maintained healthy contractions in engineered human cardiac cells, while a pocket-sized prototype supplied the sticker’s batteries and electronics.
Around 3 million U.S. adults live with surgically implanted pacemakers; the team envisions a one-time gene-therapy injection could one day enable a noninvasive alternative.
MIT now plans to merge the pacing sticker with its earlier ultrasound-imaging patch, aiming for a closed-loop wearable that can both monitor and regulate the heart.
Will ultrasound stickers soon treat everything from arrhythmia to Alzheimer's disease without surgery?
Is swapping heart surgery for permanent gene therapy a risk worth taking for patients?
Surgery-Free Ultrasound Pacemaker: The MIT Sonogenetics Breakthrough Transforming Cardiac Care in 2026
Overview
In June 2026, a revolutionary surgery-free pacemaker developed by an MIT team marks a major breakthrough in cardiac care. This new ultrasound pacemaker design aims to provide noninvasive heart stimulation, transforming how heart rhythm disorders are managed. Unlike traditional pacemakers that require invasive surgery and direct contact with cardiac tissue, the new device uses ultrasound to stimulate the heart without surgery. This innovation brings the long-held dream of noninvasive heart stimulation closer to reality, promising to reduce risks and recovery challenges for patients while maintaining the life-saving benefits of traditional pacemakers.
