Harvesting biomechanical energy in vivo is an important route in obtaining sustainable electric energy for powering implantable medical devices. Here, we demonstrate an innovative implantable triboelectric nanogenerator (iTENG) for in vivo biomechanical energy harvesting. Driven by the heartbeat of adult swine, the output voltage and the corresponding current were improved by factors of 3.5 and 25, respectively, compared with the reported in vivo output performance of biomechanical energy conversion devices. In addition, the in vivo evaluation of the iTENG was demonstrated for over 72 h of implantation, during which the iTENG generated electricity continuously in the active animal. Due to its excellent in vivo performance, a self-powered wireless transmission system was fabricated for real-time wireless cardiac monitoring. Given its outstanding in vivo output and stability, iTENG can be applied not only to power implantable medical devices but also possibly to fabricate a self-powered, wireless healthcare monitoring system.
在体内采集生物力学能量是为植入式医疗设备提供可持续电能的重要途径。在这里，我们展示了一种用于体内生物力学能量采集的创新型植入式摩擦纳米发电机（iTENG）。在成年猪的心跳驱动下，与已报道的生物力学能量转换设备的体内输出性能相比，输出电压和相应电流分别提高了 3.5 倍和 25 倍。此外，对 iTENG 的体内评估表明，在长达 72 小时的植入过程中，iTENG 在活动动物体内持续发电。由于其出色的体内性能，我们构建了一个自供电无线传输系统，用于实时无线心脏监测。鉴于其出色的体内输出和稳定性，iTENG 不仅可用于为植入式医疗设备供电，还可能用于制造自供电、无线医疗保健监测系统。
