植入式医疗器械（imd）已成为提高生活质量和延长患者寿命不可或缺的医疗工具。缩短和延长使用寿命是imd开发面临的主要挑战。目前这方面的创新研究主要集中在利用生理环境或身体自然活动产生的能量进行内部充电。为了有效地收集生物机械能，具有复杂结构和材料设计的压电和摩擦电能量采集器已经被开发出来。来自身体运动、肌肉收缩/放松、心肺运动和血液循环的能量被捕获并用于为医疗设备供电。该领域的其他最新进展包括利用peng和teng通过生物压力/应变传感来认知生物过程，或直接干预它们进行一些特殊的自供电治疗。未来的机会在于制造智能、灵活、可拉伸和/或完全可生物降解的自供电医疗系统，用于监测生物信号和治疗各种体外和体内疾病。
Implantable medical devices (IMDs) have become indispensable medical tools for improving the quality of life and prolonging the patient's lifespan. The minimization and extension of lifetime are main challenges for the development of IMDs. Current innovative research on this topic is focused on internal charging using the energy generated by the physiological environment or natural body activity. To harvest biomechanical energy efficiently, piezoelectric and triboelectric energy harvesters with sophisticated structural and material design have been developed. Energy from body movement, muscle contraction/relaxation, cardiac/lung motions, and blood circulation is captured and used for powering medical devices. Other recent progress in this field includes using PENGs and TENGs for our cognition of the biological processes by biological pressure/strain sensing, or direct intervention of them for some special self‐powered treatments. Future opportunities lie in the fabrication of intelligent, flexible, stretchable, and/or fully biodegradable self‐powered medical systems for monitoring biological signals and treatment of various diseases in vitro and in vivo.
