Based on the camouflage abilities of octopuses, squid and cuttlefish, U.S. engenieers have created a camouflage device that can change colors in response to its environments.
The device comprises a few layers and the top layer has a dye, which is temperature-sensitive. The dye is black at low temperatures and turns clear at high temperatures.
"Our device sees color and matches it. It reads the environment using thermochromatic material," explains Jon Rogers from the University of Illinois at Urbana.
