Design of the beetle inspired foldable wing. (a, b) Hindwing in a Japanese horn beetle. Wing is supported with three main frames. (c) Main crease pattern found at the center of the wing. (d) 3D model of designed foldable wing. Frames (green) are designed based on above three main frames. Crease patterns are introduced by reinforcing facets with 0.1Â mm clearance (yellow). (e) 3D printing of wing structures on PP film. (f, g) 3D printed foldable wings and flapping drone.
