Core Viewpoint - A groundbreaking micro pacemaker has been developed by a collaboration of institutions including the University of Chinese Academy of Sciences, Tsinghua University, Peking University, and Fuwai Hospital, which can generate its own power from the heart's beats, eliminating the need for battery replacements [1][3]. Group 1: Innovation in Medical Technology - The new micro pacemaker is capsule-sized and can be implanted through a minimally invasive procedure via the femoral vein, significantly reducing surgical trauma compared to traditional pacemakers [1]. - This device features a built-in micro power station that converts each heartbeat into approximately 40 microjoules of energy, which exceeds the energy requirements for its long-term operation [3]. - The design includes a magnetic levitation structure that minimizes friction and energy loss, enhancing the efficiency of the device [5]. Group 2: Clinical Application and Future Prospects - The technology has been successfully tested in animal models, specifically in pigs with arrhythmias, where it operated autonomously for one month while regulating heart rhythms and generating power from heartbeats [5]. - This innovation represents a shift from traditional pacemakers, which require regular maintenance, to a more integrated and life-long companion for patients, reflecting a deeper integration of technology into biological rhythms [5].
