Camouflage Fabrics Are Just a Couple Tentacle Steps Away (8 to be exact)
Using meta materials found in cephalopods to create materials that can blend-in with their surroundings.
Cephalopods have a protein in their skin that allows them to "see" color. We have the same protein in our eyes. A challenge that will eventually arise to engineers will be to figure out how to make the material see the light around it and change its color to make it. Another challenge designing a systems that reacts and displays the vivid camouflage patterns.
Researches at Rice university have made a breakthrough that get us one step closer to creating camouflaging materials. Using red,blue and green hues, usually found in high end LCD televisions, five micron square pixels that each contain hundreds of aluminum nano-rods. By varying the length of these nano-rods and the spacing between them they can create pixels that produce dozens of colors, including rich reds,greens and blues, comparable to those found in High-definition LCD televisions. This new break through will hopefully bring us closer to creating fabrics that can change color. New breakthroughs later on might help to be able to sense light in wave form and be able to transform the material in to that particular color.
