Light-controlled self-assembling material knows when to fold 'em

2 pictures NC State University researchers have developed a method that uses light to control the order in which a self-folding material makes each fold We’ve previously seen self-folding structures that are triggered by light, and it’s a technique that works well for turning flat planes into simple 3D shapes like cubes and pyramids. In an effort to make these smart materials smarter, scientists have now developed a new method for making complex self-folding structures by varying the color of the light and the "hinges" so that each section of the material folds in a specific order. The new […]
