Know how researchers created a synthetic material, elastomers, that can change color and texture to specific voltage change, like that of cephalopods — elastomer Learn about elastomers that are changeable in colour and texture, much like the skin of octopuses and other cephalopods. In the elastomers, these changes take place under electrical stimulation.

Under normal conditions, the long-chain polymers that compose an elastomer exist in an irregularly coiled, compact state. When an external force is applied to the material, these coiled chains straighten out in the direction of the pull. Once the force is released, the molecules spontaneously return to their original, random arrangement, allowing the material to recover its shape.1
