Pacemaker Powered By Light Eliminates Need For Batteries And Allows The Heart To Function More Naturally. Scientists have designed a solar panel-like pacemaker that can precisely control heartbeats.
Scientists have designed a solar panel-like pacemaker that can precisely control heartbeats.
Thinner than a human hair, our pacemaker is made of an optic fiber and silicon membrane that the Tian lab and colleagues at the University of Chicago Pritzker School of Molecular Engineering have spent years developing. Unlike conventional solar cells that are usually designed to collect as much energy as possible, we tweaked our device to generate electricity only at points where light strikes so it can precisely regulate heartbeats. Our ultralight device gently conforms to the surface of the heart, enabling less invasive stimulation and improved pacing and synchronized contraction.
