Scientists have recently developed a ‘self-powered’ cardiac pacemaker that could revolutionize traditional devices reliant on batteries. This innovative implant harvests the body’s own bioenergy—such as from heartbeats, breathing, or temperature fluctuations—and converts mechanical or thermal energy into electricity using piezoelectric or thermoelectric materials. Animal trials have already demonstrated its feasibility, with the device operating reliably for months without battery replacement. Conventional pacemakers typically require surgical battery replacement every 5 to 10 years, posing risks of infection and added burden on patients. In contrast, the self-powered version could drastically reduce the need for repeated surgeries, improving patient quality of life and lowering healthcare costs. Moreover, the technology holds promise for miniaturization and could be integrated into other implantable medical devices in the future, such as neural stimulators or glucose monitors. Although still in the experimental stage, this breakthrough paves the way for next-generation, intelligent, and sustainable medical electronics.
近日，科学家成功研发出一种“自供电”心脏起搏器，有望彻底改变传统起搏器依赖电池的局限。这种新型设备利用人体自身的生物能量——如心跳、呼吸或体温变化——通过压电材料或热电转换技术，将机械能或热能转化为电能，从而持续为起搏器供电。研究团队在动物实验中已验证其可行性，设备在无需更换电池的情况下稳定运行数月。传统起搏器通常每5至10年需手术更换电池，不仅增加患者负担，也存在感染风险。而自供电起搏器可显著减少手术次数，提升患者生活质量，并降低医疗成本。此外，该技术还具备微型化潜力，未来或可集成到其他植入式医疗设备中，如神经刺激器或血糖监测仪。尽管目前仍处于实验室阶段，但这一突破为下一代智能、可持续的医疗电子设备铺平了道路。
