Abstract

Abstract: In recent years, kirigami – the ancient art of paper-cutting – has been widely studied by scientists and engineers in various fields such as structural mechanics, materials, optics, electronics, robotics, and bioengineering. Kirigami is a combination of slits and creases; therefore, a kirigami structure has a cutting step that is not involved in making an origami structure. In general, a kirigami structure starts from a continuous planar sheet, forms a new shape by cutting or carving, and finally acquires a new structural configuration by stretching, folding, or other external stimuli. Kirigami is considered to be an innovative and effective method for advanced three-dimensional micro- and nano-manufacturing by providing different fabrication strategies through cutting and folding thin sheets. Furthermore, kirigami is generally used as a technique to make (meta)materials and (meta)structures with extraordinary properties such as negative Poisson's ratio. In doing so, a given material/structure is transformed into a metamaterial/metastructure with properties which do not exist in the initial material/structure. In this paper, from the perspective of geometric design, kirigami patterns are categorized into two groups: (1) cut-only kirigami, and (2) cut-and-fold kirigami. Moreover, the patterns are classified into five categories as follows: fractal cut, ribbon, lattice, zigzag, and closed-loop kirigami. Physical models are made and presented to demonstrate the design and geometric properties of these kirigami patterns. Finally, this review summarizes the current developments in kirigami-inspired metastructures and metamaterials and concludes with a future outlook of their potential applications in science and engineering.
