Squids affect the pigmentation of their skin by increasing or compressing the volume of cells, for which a certain group of proteins is responsible, because of their properties called Reflexins (from the English. "reflection" - reflection, reflection). Scientists were able to reproduce this process using aluminum. Blotches of this metal were applied to the surface of an elastic polymer. When expanded, the resulting material reflects significantly more infrared radiation, and when compressed, the tissue becomes almost completely invisible to infrared observing devices.
The development is not yet ready for field trials, but scientists believe that in the future it will find application in the armed forces as a component of army camouflage. In addition to its camouflage properties, the material is very easy to produce on an industrial scale, and its cost is very low.
