Scientists have unveiled a synthetic skin inspired by octopus camouflage that is capable of changing colour and texture, opening up potential uses from robotics to display technologies.
Researchers used semiconductor etching techniques to recreate the marine mollusc’s ability to hide by changing its appearance to resemble its environment.
The researchers exploited how roughening or smoothing surfaces can make the light they reflect look different to an observer, creating a much broader visual palette than relying on colour variations alone.
