Light used to remotely control curvature of plastics
Researchers at North Carolina State University have developed a technique that uses light to get two-dimensional (2-D) plastic sheets to curve into three-dimensional (3-D) structures, such as spheres, tubes or bowls. The advance builds on earlier work by the same research team, which focused on self-folding 3-D structures. The key advance here is that rather than having the plastic fold along sharp lines — into polygonal shapes […]
