Triboelectric nanogenerator (TENG) has wide applications in implantable biomonitoring, man-machine interaction, internet of things and smart city, et al. Continuously enhancing its output performance is the main challenge in the development of TENG. In this present, firstly, we will talk how to utilize the high temperature originally harmful to the performance of TENG to increase the output performance by rational design <sup>[1]</sup>. Then, the inhomogeneous triboelectric charge distribution and its cancellation effect on driving the free electrons flowing in the external circuit is pointed out to result in the low output of the flutter-driven triboelectric nanogenerators, and the method of electrode segmentation and integration is developed to enhance the output performance <sup>[2]</sup>. After that, the electric field distribution inside and outside TENG is detailly analyzed, and the outside electric field change is utilized to enhance the output current density <sup>[3]</sup>, and simultaneously enhance the output current and output voltage <sup>[4]</sup>.<br/> <br/>References:<br/>[1] B.L.
