近日，中国科学家成功研发出一种革命性技术，可将心脏跳动产生的机械能转化为电能，为植入式医疗设备（如心脏起搏器）持续供电，使心脏本身成为‘生物充电宝’。这项技术基于压电材料和柔性纳米发电机，能够高效捕获心跳过程中产生的微小能量，并将其稳定转化为可用电力。研究团队来自中国科学院北京纳米能源与系统研究所，他们通过动物实验验证了该装置的安全性和有效性。未来，该技术有望大幅减少患者因更换电池而需反复接受手术的痛苦，延长植入设备的使用寿命，甚至推动自供能健康监测系统的发展。这一突破不仅体现了中国在生物医学工程与能源交叉领域的创新能力，也为全球数百万依赖植入式电子设备的患者带来新希望。
Recently, Chinese scientists have developed a groundbreaking technology that converts the mechanical energy generated by heartbeats into electricity, effectively turning the human heart into a ‘biological power bank’ to continuously power implantable medical devices such as pacemakers. The innovation relies on piezoelectric materials and flexible nanogenerators capable of efficiently harvesting the tiny amounts of energy produced during each heartbeat and converting it into stable, usable electricity. The research team, from the Beijing Institute of Nanoenergy and Nanosystems at the Chinese Academy of Sciences, has successfully demonstrated the safety and efficacy of the device in animal trials. In the future, this technology could significantly reduce the need for repeated surgeries to replace batteries, extend the operational lifespan of implanted devices, and even enable self-powered health monitoring systems. This breakthrough not only highlights China’s growing prowess at the intersection of biomedical engineering and energy innovation but also offers new hope to millions of patients worldwide who rely on implantable electronic medical devices.
