Summary: Two-dimensional materials like graphene and molybdenum disulfide offer new possibilities for electronics, optics, and biosensing applications. By using kirigami/origami techniques, these materials can be reshaped into three-dimensional structures, expanding their applications and enhancing device performance. This shaping strategy not only integrates 2D materials with 3D structures controllably, but also opens up new ways to enhance the properties of 2D materials and develop innovative functions.

Summary: Thick-panel kirigami is a technique for constructing deployable structures by cutting open creases on origami structures, which can be applied to structures with different curvatures. It provides accurate and precise deployment motion by converting creases to rotational hinges. However, the substitution of creases with slits may lead to motion singularity. This study discusses the motion singularity of thick-panel kirigami structures and validates the analysis through physical prototypes.

Summary: We propose an additive approach for inverse design of kirigami-based mechanical metamaterials, focusing on empty spaces rather than solid tiles. By treating each negative space as a four-bar linkage, we establish a recursive relationship between adjacent linkages, enabling efficient kirigami pattern creation. This approach utilizes elementary linear algebra to solve the design problem, encoding compatibility, reconfigurability, and rigid-deployability through a matrix multiplication-based iterative procedure. By employing this strategy, we overcome the challenges of non-convex optimization and achieve control over deployment angles, linkage offsets, and boundary conditions. Our work demonstrates the creation of various rigid-deployable, compact, and reconfigurable kirigami patterns, fabricated using two different strategies. Overall, our additive approaches offer efficient routes for mechanical metamaterial design and fabrication based on origami/kirigami art forms.

Experimental results show that the origami-structured fishtail can save up to 92.3% energy compared with the traditional fishtail, and the novel hybrid neutral layer can save up to 56.7% energy compared to the fishtail with a rigid neutral layer. The fabricated bionic fish with the innovative fishtail demonstrates good straight-line swimming direction and turning ability, providing an important reference for bionic design to mimic real fish.
