World's Smallest Pacemaker: A Game-Changer for Newborn Heart Care
Breakthrough alert: Northwestern University researchers have developed a pacemaker smaller than a grain of rice—just 1.8 mm wide! Designed for newborns recovering from heart surgery, this marvel of medicine is injectable, wireless, battery-free, and fully dissolvable inside the body.
It’s powered by body fluids, regulated by light pulses via a soft chest patch, and vanishes when no longer needed—no surgery, no wires, no scars.
This is the future of pediatric care—gentle, smart, and brilliantly life-saving.
