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

Researchers have developed a wireless, ultrathin pacemaker powered by light that eliminates the need for batteries and operates like a solar panel. This innovative design conforms to the heart’s contours and can precisely stimulate multiple areas of the heart using light-generated electrical signals. The pacemaker is thinner than a human hair, can be implanted without chest opening, and has been successfully tested in rodents and pigs. Future research aims to explore long-term effects, durability, and potential applications beyond cardiac care. This advancement could revolutionize heart treatments and reduce the need for invasive surgeries.
