Tens of thousands of people have their lives improved with a heart pacemaker. Since the first pacemakers were implanted more than fifty years ago designs have improved so that pacemakers can adjust their pacing rate automatically and battery life gives years between operations for battery replacement. Now there is the prospect of pill-sized pacemakers powered by external wi-fi signals and heart-repair with engineered heart cells, removing the need for the current bulky technology. All these impr

Scientists at Northwestern University have developed the world's smallest pacemaker — so tiny it can be injected through a syringe and activated by light. Designed especially for newborns and patients who need temporary heart support, this pacemaker works without wires, bulky batteries, or surgery. Once it’s no longer needed, it harmlessly dissolves inside the body, eliminating the risks of surgical removal. Powered by a simple chemical reaction with body fluids and triggered by light pulses fro
