报告摘要：
Recently, piezoelectric nanogenerator (PENG) and triboelectric nanogenerator (TENG) have attracted much attention and been considered as another potential solution for harvesting mechanical energy. With its high output performance, outstanding biocompatibility and low cost, nanogenerator (NG) has been studied for powering implantable and wearable electronic medical devices.
Here, we demonstrated the application of nanogenerators in biomedical science and health care. The NGs can convert the mechanical energy from human motion into electricity and drive the implanted long-term self-powered medical devices or biosensors. Different biomechanical-energy harvesters based on NGs were invented which worked as power sources in self-powered medical electronics or as active sensors for disease detection. An implantable triboelectric nanogenerator (iTENG) in a living animal has been developed to harvest energy from its periodic breathing. The energy generated from breathing, body movement and heart beating was used to power a symbiotic cardiac pacemaker in vivo of a pig, which could regulate the heart rate and cure heart arrhythmia of the large animal. Another low-level laser cure (SPLC) system was also demostrated for accelerating the proliferation and differentiation of osteoblast, which can be used for bone and tooth repairing. In vivo real-time acquisition and wireless transmission of self-powered cardiac monitoring data was also demonstrated for the first time. A wearable and flexible self-powered pulse sensor based on NG has been applied to diagnose and antidiastole of coronary heart disease, atrial septal defect and atrial fibrillation from health. These works are concentrated in the field of medical devices, biosensors and disease detection devices. It showed broad clinical applications of self-powered medical systems for biomedical science and health care.
