| Outline of Final Research Achievements |
This study developed the new observing methods for wing folding/unfolding techniques in insects by using high-speed cameras and the 3D measuring systems. Based on these techniques, wing folding/unfolding mechanisms in a rove beetle and a ladybird beetle were clarified. This study also used the origami geometry and proposed the geometric model to explain the wing transformation mechanisms from the point of view of the elastic deformation. By applying these achievements, the generalized crease patterns that can be used in the design of the deployable structures were proposed. From an engineering standpoint, these wings have an interesting property: they can achieve compact storing without compromising the strength and stiffness of the wing structure. These finding constitutes an indispensable initial foothold to apply above excellent properties in artificial structures.
