Figure 1

(a) Schematic diagrams of a wind tunnel and the structural design of a flutter-driven triboelectric generator including surface characteristics of (i) a highly flexible flag and (ii) a counter plate and (iii) the fabrication of the counter plate. (b) Fluttering images of a stand-alone configuration of dimensions 7.5 × 5 cm as captured with a high-speed camera. (c) The regime map of the dynamic interaction between a flag and a plate.
