Origami, the Japanese art of folding paper into decorative shapes and figures, has long been an inspiration for industrial design. The concept of assembly was used to construct reconfigured structures that change their function by changing shape. These designs are promising for applications such as nanorobots for drug delivery, sophisticated solar panels for aerospace engineering, and cladding and shading for architecture. However, most of these designs do not withstand heavy loads. Those who can are able to do so only in a certain direction, collapsing in the direction in which they are composed. This limits their use as construction materials.
A study by a team of McGill University researchers may provide a solution to this limitation. By merging concepts with origami and kirigami, the practice of folding and cutting paper, researchers have developed a class of cellular metamaterials that can be flat folded and fixed in several positions that remain rigid in different directions.
“Their load-bearing capacity, flatness and reprogrammability can be used to deploy structures, including certain submarines, reconfigured robots and low-volume packaging,” said Damiana Passini, professor of mechanical engineering and lead researcher. . “Our metamaterials remain solid in several ways, but are rigidly complex metamaterials, unprecedented attributes in modern literature.”
The study was published in The nature of communication.
