World's Smallest Injectable Pacemaker Promises Revolutionary Heart Care
Researchers at Northwestern University have achieved a breakthrough in bioelectronics with the creation of the world’s smallest injectable pacemaker, a technological marvel capable of powering itself using the body’s own fluids and dissolving after its temporary use. This innovation paves the way for significant advancements in how we treat congenital heart defects, particularly in infants.
This ultra-miniature pacemaker, diminutive enough to fit into a syringe for injection, represents a less invasive alternative to traditional pacemakers, which often require more complex surgical procedures. As explained by John A. Rogers, a leading figure in bioelectronics at Northwestern, the device pairs seamlessly with a soft, flexible, wearable monitor attached to the patient’s chest. This wearable detects irregular heart rhythms and uses a light pulse to activate the pacemaker through the skin.
