Foldable wings in certain insects represent the ultimate deployable structure, capable of rapid folding/unfolding while possessing the strength and rigidity to withstand high-speed flapping. Among these insects, earwigs use a unique fan-like folding mechanism, allowing for the most compact wing folding in insects. The authors have elucidated a geometrical design method to apply the intricate folding patterns of earwig fans to various forms of deployable structures. In this paper, we show new deployable structures developed through biomimetics, including paper fans, tents, deployable roofs, and providing insights into deployable solar panel arrays designed for lunar base applications.
