メッシュレイヤージャミング: 曲面を覆うことができる可変剛性シートの開発

抄録

We propose a mesh layer-jamming sheet that changes its stiffness based on the internal air pressure. The proposed sheet is more flexible than layer-jamming sheets when the internal air pressure is at the atmospheric level and more rigid than fabric jamming sheets when the internal air is evacuated. Mesh sheets made of polyester fibers elongate by changing the mesh shape without elongation of the fibers. The proposed layer-jamming sheet envelopes the mesh sheets inside a flexible membrane, and provides both the flexibility and high bending stiffness of layer-jamming sheets. The proposed layer-jamming sheet can wrap around a curved surface without creating wrinkles.
