3D-printed smart gel changes shape when exposed to light

Inspired by the color-changing skin of cuttlefish, octopuses and squids, engineers have created a 3D-printed smart gel that changes shape when exposed to light, becomes 'artificial muscle' and may lead to new military camouflage, soft robotics and flexible displays. The engineers also developed a 3D-printed stretchy material that can reveal colors when light changes.
