Origami, kirigami inspire mechanical metamaterials designs

Researchers categorize origami- and kirigami-based mechanical metamaterials, artificially engineered materials with unusual mechanical properties, and subdivided them into rigid or deformable categories based on the elastic energy landscape. The researchers want to discover new designs, especially curved origami designs, hybrid origami-kirigami designs, modular designs, and hierarchical designs; to design for real-world applications, it will be helpful to explore materials with different properties such as thin or thick, soft or hard, and elastic or plastic.
