Current Development on Origami/Kirigami‐Inspired Structure of Creased Patterns toward Robotics

Abstract

Origami/kirigami, the ancient art of paper folding and cutting techniques, has provided considerable inspiration for structural design routes in the engineering and medical fields over the last few decades. The practicability of the methods and concepts of origami/kirigami has been demonstrated in several emerging classes of technologies, e.g., stretchable electronics, deformable devices, self‐assembly fabrication, etc. More and more related products are produced pursuing a folding form for better storage, deformation capacity, and multifunction realization. Herein, the innovative creased patterns of origami/kirigami designs are distinguished and discussed, and the four most widely used creased pattern types are introduced, which may potentially provide origami/kirigami related inspiration and additional solutions toward many research fields.

Flexible Sensory Systems: Structural Approaches

“…The origins of origami and kirigami are in ancient papercraft techniques that involve folding and cutting the substrate and extending the use of materials from papers to a broad range of alternatives. Both structures provide a way to apply flat thin planes into 3D structures for various engineering fields, in which a broad range of materials is needed, such as electronics [ 132 , 133 , 134 , 135 , 136 ], optics [ 137 , 138 ], biomedical sensing [ 15 , 135 , 139 ], robotics [ 140 , 141 , 142 , 143 ], and flexible device [ 134 , 135 , 136 , 138 , 144 , 145 ] applications. Owing to their characteristics, which can modulate the material simply and easily, origami and kirigami structures have been fabricated with various materials, such as metals [ 133 , 144 , 146 , 147 , 148 ], polymers [ 144 , 147 , 149 , 150 , 151 , 152 ], graphene [ 153 , 154 ], and hydrogels [ 142 ], from the scale of meter to micro/nanometer size.…”

“…Origami/kirigami methods are considered to be good candidates, as their fabrication methods are applicable in micro/nanoscale and the possibility of using various materials that could not to be used due to property limitations. Since origami/kirigami structures are easy to configure, they have been developed and applied in various fields, such as electronics [ 132 , 133 , 134 , 135 , 136 ], optics [ 137 , 138 ], biomedical sensing [ 15 , 135 , 139 ], robotics [ 141 , 142 , 143 ], and flexible devices [ 134 , 136 , 138 , 144 , 145 ]. Self–folding methods using lights, heat, capillary force, and residual stresses are being applied to fabricate the structures to be folded in origami structures; however, they still limit the use of materials in their properties.…”

Engineering by Cuts: How Kirigami Principle Enables Unique Mechanical Properties and Functionalities

“…tunable mechanical properties, and ease of integrating electronic components, micro/nanoscale sensors, and actuators. [99,163,164] The two most fundamental tasks for soft robots are object manipulation and locomotion. Regarding the former task, soft robotic manipulators have exceptional adaptability, allowing them to grasp and handle objects with irregular shapes autonomously.…”
