报告摘要：
The low charge density and energy utilization efficiency are two key factors for triboelectric nanogenerator (TENG) to improve its output performance. Recently reported charge pumping method and LC buck strategy partly improved the issues above, but it is still far from enough for the commercial applications. Here, inspired by the historical development of electromagnetic generators and switched capacitor convertor, we propose self-charge excitation TENG and fractal-design based switched-capacitor-convertors, achieving 1.25 mC m-2 high charge density and 94% energy transferred efficiency, respectively. The novel designs may provide two promising strategies for achieving high-output TENG towards practical applications.
