#Pacemaker

A breakthrough in bioelectronics offers a glimpse of a less invasive future for treating congenital heart defects in infants. Researchers have developed the world’s smallest injectable pacemaker that powers itself from the body’s fluids and dissolves after temporary use, reducing the need for open-heart procedures.

The ultra-miniature device is designed to be injected via syringe and works with a soft, chest-worn monitor. The monitor detects irregular heart rhythms and activates the pacemaker through the skin with a light pulse. This approach aims to simplify care while protecting the health of young patients.

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.
