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.
