Researchers have developed a material which can change colour and texture on command, inspired by the shape-shifting camouflage abilities of some cephalapods.
The team use a beam of electrons to draw designs onto a polymer which is then exposed to water. When wet, the polymer swells and reveals the textures patterned into it with the electron beam.
The researchers say that this tunable photonic skin could be used in wearable devices or soft robots.
