Abstract

Modular origami is a metamaterial that assembles origami or kirigami modules through simple connections such as gluing, which has been little studied in metamaterials. However, it may offer new approaches to the design of mechanical metamaterials due to the unique advantage that material properties and scale do not limit its structure. A novel modular origami structure is developed based on the Miura pattern. It exhibited a significant negative Poisson's ratio and negative stiffness while falling into the rigid folding. Through geometric analysis, we investigate the relationship between the unique kinematics and mechanical properties of this new three-dimensional modular origami structure. In addition, the experiment results showed that the Poisson's ratio of the structure differed remarkably in different directions and is related to the length and angle of each side of the structure. This rigid foldable structure with negative Poisson's ratio and negative stiffness laid a solid foundation for other mechanical metamaterial designs.
