🧪 Taking a cue from the master of disguise – the #octopus – researchers have created a 4D-printed synthetic skin that can morph its texture and reveal hidden information.By encoding #data into a single layer of hydrogel, the material can shift from a flat sheet to a #3D shape or reveal a hidden image when the temperature changes. https://scitechdaily.com/a-new-smart-skin-changes-shape-texture-and-appearance-on-command/#biomimicry #robotics #science #nature #engineering #stem #innovation
