Researchers at Tufts University School of Engineering 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 take about one second to form, are stable, but can be erased by flooding the surface of the silk with vapor, allowing the researchers to “reverse” the printing and start again. In an article published in the Proceedings of the National Academy of Sciences, the researchers demonstrate examples of the silk wrinkle patterns, and envision a wide range of potential applications for optical electronic devices.1
