MIT's Smart Material Folds into Any 3D Shape with a Pull

Scientists have created a groundbreaking material that mimics the principles of kirigami, a Japanese paper art form. This innovative material can transition from a flat, tiled pattern into complex three-dimensional shapes simply by pulling a small string. The research team developed a sophisticated algorithm that precisely cuts and encodes material properties, enabling its transformation. This new technology, pioneered by researchers at MIT, offers a unique approach to creating deployable structures.

The core of this innovation lies in an algorithm that converts user-defined 3D models into a flat, foldable grid. This process is akin to how kirigami artists imbue paper with special characteristics through strategic cuts. The algorithm calculates the ideal string path, ensuring a smooth and efficient conversion to the intended 3D form. This mechanism is described as an auxetic one, meaning it expands when stretched and contracts when compressed, adding to its versatility.
