Researchers at the University of Chicago have developed an ultra-thin pacemaker powered by light, offering a minimally invasive alternative to traditional devices.
Inspired by solar cell technology, the pacemaker utilizes light to stimulate the heart, reducing the need for wires and external batteries. The device, just one micrometer thick and weighing a fraction of conventional pacemakers, dissolves harmlessly in the body over time. With potential applications beyond cardiac care, this innovation marks a new era in bioelectronics.
