Pacemaker powered by light eliminates need for batteries and allows the heart to function more naturally—new research

By harnessing light, my colleagues

designed a wireless, ultrathin pacemaker that operates like a solar panel. This design not only eliminates the need for batteries but also minimizes disruptions to the heart’s natural function by molding to its contours. Our research, recently published in the journal Nature, offers a new approach to treatments that require electrical stimulation, such as heart pacing.
