Our country's scientists have developed a "capsule version" self-powered miniature pacemaker.

After nearly seven years of collaborative research, a research team composed of several units including the University of the Chinese Academy of Sciences, Tsinghua University, Peking University, and several hospitals has made significant progress in the field - successfully developing a capsule-sized micro-symbiotic self-powered wireless pacemaker for the heart. Recently, the related research results were published in the authoritative journal "Nature-Biomedical Engineering". The core innovation of this pacemaker is the integration of a highly efficient energy regeneration module: it can capture kinetic energy from the heart's own beating through electromagnetic induction technology and convert it into electrical energy. Tests have shown that its output power has exceeded the critical energy threshold for the lifelong operation of pacemakers, ensuring stable driving of the pacing circuit and precise control of the heart rhythm. Additionally, the device has been designed with high micro-miniaturization and excellent biological compatibility and blood compatibility, supporting minimally invasive implantation through catheters and greatly reducing surgical trauma.
