Based on the camouflage abilities of octopuses and cuttlefish, engineers in the US have built a flexible material that changes colour to match its surroundings.
The new design features a grid of 1mm cells, containing a temperature-driven dye that switches colour on demand.
So far it only responds in black-and-white, but the team hopes that the principles of their design will have commercial and military applications.
The work appears in the journal PNAS.
