In a groundbreaking medical innovation that could redefine cardiac care, researchers at MIT and Stanford have unveiled a rice-sized pacemaker that requires no wires, no batteries, and no surgery. Even more astonishing: once its job is done, the device dissolves naturally inside the body.
This futuristic pacemaker, developed using bioresorbable materials, is designed to monitor and regulate irregular heartbeats for a specific period—typically a few weeks to months. During this time, it delivers targeted electrical pulses to stabilize cardiac rhythms after events like surgery or heart attacks. Once the heart regains normal function, the pacemaker simply melts away, leaving no trace and eliminating the need for a second procedure to retrieve it.
Dr. Elena Vasquez, the lead biomedical engineer on the project, said, “This is a massive step forward in temporary cardiac therapy. Patients no longer have to deal with bulky implants, external wires, or the risks of post-op infections and secondary surgeries.”
The device operates wirelessly using external power transmitted through near-field communication (NFC)—similar to the tech in contactless payments—and is made from a blend of magnesium, silicon, and biodegradable polymers.
Early trials on animal models have shown remarkable success, and human clinical trials are expected to begin by early 2026.
Experts hail this as a major leap in bioelectronics and regenerative medicine, opening doors to similar dissolvable devices for other organs.
If successful, this innovation could transform post-operative cardiac care and offer safer, more patient-friendly solutions in the future.
