The line of new origami materials is rapidly expanding. This time, the attention of researchers at the Harvard School of Engineering, John Paulson, was attracted by a variety of origami - kirigami, where the main emphasis is not on folds, but on cuts, as a result of which the structure and function of the material changes.
In an article published in the journal Physical Review Letters, the researchers demonstrated how a thin perforated sheet turns into a 3D structure when a material is stretched with characteristic cuts.
Scientists have found that the more a material is stretched, the more permanent the temporary deformations become. They also noted that the emerging pattern, as a result of mechanical influences, can be adjusted by changing the orientation of the incisions.
“The study demonstrates the possibility of using kirigami technology to produce transformable structures from completely flat sheets. The only condition is that perforation must be applied to the sheets in advance, ”explains one of the project participants, Katya Bertholdi.
