报告摘要👨🏿‍🍳：Implantable medical devices and integrated wireless healthcare sensors are attracting extensive attention, but the batteries used for powering these devices usually display a limited lifetime. Sustainable power sources for cardiac pacemakers, neural stimulators and other implantable biomedical devices are required. Mechanical energy was considered as one of most abundant and accessible energy sources around the human body. A small system, which can efficiently convert mechanical energy in our daily life, would be a suitable solution for electricity generation and significantly extend the lifetime of the electronic devices, especially in medical area.

Recently, triboelectric nanogenerator (TENG) has attracted much attention and been considered as another potential solution for harvesting mechanical energy. With its high output performance, outstanding biocompatibility and low cost, TENG has been studied for powering implantable medical electronic devices. Here, we demonstrated an in vivo biomechanical-energy harvesting using a TENG. An implantable triboelectric nanogenerator (iTENG) in a living animal has been developed to harvest energy from its periodic breathing. We also developing an encapsulation method for protecting iTENG from the contamination or liquid infiltration of the surrounding environment. The energy generated from breathing and body moving was used to power a prototype pacemaker and a low-level laser cure (SPLC) system, respectively. It was found that the self-powered system could regulate the heart rate of a rat and significantly accelerated the mouse embryonic osteoblasts' proliferation and differentiation. The iTENG also employed as an in vivo cardiovascular monitor and for powering an in vivo wireless signal transmitter. This is a significant progress for fabricating self-powered implanted medical electronic devices and sensors using TENG.
