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.

Material scientists learn how to make 3D-printed liquid crystal shape-shift

Researchers show that by controlling the printing temperature of liquid crystal elastomer, or LCE, they can control the material's degree of stiffness and ability to contract - also known as degree of actuation. What's more, they are able to change the stiffness of different areas in the same material by exposing it to heat.
