New silk materials can wrinkle into detailed patterns, then unwrinkle to be 'reprinted'

October 8, 2019 0 Comments 3-D Printing, Artificial intelligence, Computer Graphics, Computer Science, Information Technology, Materials Science, Nature of Water, Textiles and Clothing

Engineers have developed silk materials that can wrinkle into highly detailed patterns — including words, textures and images as intricate as a QR code or a fingerprint. The patterns are stable, but can be erased by flooding the surface of the silk with vapor, allowing the surface to be printed again. The researchers demonstrate multiple examples of the silk wrinkle patterns, and envision a wide range of potential applications for optical electronic devices.
