Pacemaker Powered By Light Eliminates Need For Batteries And Allows The Heart To Function More Naturally

Posted on Categories Discover MagazineLeave a comment on Pacemaker Powered By Light Eliminates Need For Batteries And Allows The Heart To Function More Naturally

By harnessing light, my colleagues and I 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.Pacemakers are medical devices implanted in the body to regulate heart rhythms.
