💨 Abstract

Scientists have developed a world's smallest pacemaker, a temporary heartbeat regulator smaller than a grain of rice. The device, wireless and injectable, can be controlled by light and dissolves in the body when no longer needed. The study describes the device in the journal Nature. The pacemaker, still years away from human trials, is aimed at helping children born with congenital heart defects and adults recovering from heart surgery.
