Discovering kirigami patterns | Nature Computational Science


May 25, 2023

A computational tool primarily based on an additive strategy and linear algebra has been created collectively with a fabrication technique for the systematic exploration of rigid-deployable, compact and reconfigurable kirigami patterns.

The ancient Japanese art of paper folding known as origami (from Japanese ori, which means fold, and gami which means paper) and its variant in which paper cutting is introduced, known as kirigami (from Japanese kiri, which means reduce), have attracted the focus of a lot of scientists in current years. This scientific reputation comes from the striking characteristics that can be obtained by just folding and cutting two-dimensional thin components these transformed an artistic activity into a vibrant field of scientific study and have generated a class of architected metamaterials with programmable mechanical properties1,two. Origami and kirigami have develop into engineering tools in a lot of apparently uncorrelated fields such as power-effective constructing skins, deployable structures in space satellites, self-folding robots, parachutes, biomedical devices, stretchable and versatile electronics, meals packaging, and reconfigurable microelectronic devices3. Their fascinating properties can also be combined in new hybrid configurations of origami–kirigami patterns. The potentialities of kirigami metamaterials can be totally exploited by optimizing their design and style with strong computational tools, which assist designers forecast the infinite configurations that kirigami components can provide, as effectively as uncover unseen ones with mechanical properties for new applications. One particular challenge in transforming kirigami from prototypes to genuine-life devices is represented by fabrication methods that ought to be suitably tailored to produce the complicated patterns that, by combining rigid tiles or primarily rigid portions with versatile linkages, confer to kirigami their deployable character. Writing in Nature Computational Science, Dudte et al.four have created a computational process to design and style quad-kirigami patterns though satisfying a priori defined configurations.
