Paper, Ladybird beetle–inspired compliant origami
Origami allows for compact and lightweight designs, but it usually isn’t very pliable. Ladybugs have collapsible wings controlled by a specialized vein that acts as a main frame. This type of compliant foldable design allows for energy storage as well, which means the wing can deploy quickly and also sustain aerodynamic forces. Engineers at the Seoul National University and Harvard University created a glider based on that wing using polyethylene terephthalate (PET) facets and a rip-stop fabric. Once deployed, it can lock itself to stay in the right position and is also strong enough to sustain 150 times its own weight. Overall, the glider has the important qualities of being lightweight, collapsible, quickly deployable, and be able to bear some type of load.
