The octopus is, without a doubt, the coolest animal on the planet. Not only are they really smart, they do some crazy shit without the aid of a pesky spine (or any bones at all). Now researchers in the US have created a material that mimics one of their greatest feats—changing the shape of their skin.
Released Thursday in Science, the study, led by engineers James Pikul and Rob Shepherd, presents a skin-like material that starts out flat but can inflate and expand into specific shapes. It could eventually be used for camouflage suits and new kinds of tech interfaces.
