A scalable manufacturing technique that gives materials “structural color”.
MIT researchers have developed a scalable manufacturing technique that gives materials “structural color” — color that arises as a consequence of a material’s microscopic structure, rather than from chemical additives or dyes. Here, a penny’s relief is thrown into vibrant colors when pressed into a new material developed at MIT (left). The material’s colors are then converted to a map of compressive stresses (right).
