The world’s smallest pacemaker is injectable and powered by light

Engineers at Northwestern University have developed the world’s smallest pacemaker. It’s so small, as a matter of fact, that it fits inside the tip of a syringe. This means that it’s injectable, so patients could potentially avoid a painful surgery.<br /> It safely dissolves into the bloodstream after a time, so it’s a temporary solution.
