We design a continuously rotating triboelectric nanogenerator (CR-TENG) to minimize the rotation resistance for a rotor operating at small wind speeds (~3.5 m/s), and to maximize the efficiency of sliding contact as a one-dimensional (1D) fiber rather than two-dimensional contact areas. The CR-TENG harvests electrical energy (21.6 V and 0.6 μA) from a small wind with a speed of 3.5 m/s, which is easily generated in everyday life in spite of the small contact area (0.3 cm × 0.8 cm), which is due to the surface roughness and flexibility of the 1D fiber. Furthermore, a small-sized CR-TENG with a diameter of 2 cm can harvest electrical energy (5.1 V, 8.5 V, and 23.8 V, respectively) in artificial wind (10 m/s, 20 m/s, and 30 m/s) generated in a moving carrier, so a small-sized CR-TENG with improved mobility and highly integrated density may be realized.

一维纤维摩擦的滑动接触和非接触旋转摩擦发电机

我们设计了一种连续旋转的摩擦纳米发电机（CR-TENG），以最小化在小风速（〜3.5 m / s）下运行的转子的旋转阻力，并最大化一维（1D）纤维的滑动接触效率而不是二维接触区域。CR-TENG以3.5 m / s的速度从小风中收集电能（21.6 V和0.6μA），尽管接触面积小（0.3 cm×0.8 cm），但在日常生活中仍很容易产生电能归因于一维光纤的表面粗糙度和柔韧性。此外，直径为2 cm的小型CR-TENG可以在风速为10 m / s，20 m / s和30 m / s的情况下收集电能（分别为5.1 V，8.5 V和23.8 V）。 s）在移动的载体中产生，
