Fig. 2

a Structural characteristic of the 3DB-TENG, which includes the outer braided braced frame and the inner axial core column. b Photograph image of the 3DB-TENG (scale bar: 1 cm). c Schematic illustration of the 3D four-step rectangular braiding technology. d Distribution of yarn carriers on the machine bed. The braided yarn carriers and the axial yarn carriers are marked with “O” and “X” symbols, respectively. e Traveled trajectories of one yarn carrier and its suspended yarn. The movement routes of one braided yarn and its yarn carrier are highlighted with an orange line and a black line, respectively. Moreover, the walking paths of one axial yarn and its yarn carrier are indicated with a blue line. f Schematic illustration of the working principle of the 3DB-TENG in a vertical contact and separation mode. g–i Electrical output performance of the 3DB-TENG under different loading frequencies (1–5 Hz), including (g) VOC, (h) ISC, and (i) QSC.
