The US army is looking into creating a new “smart” camouflage that mimics the rapidly changing skin colour and patterns of cephalopods. Cephalopods (cuttlefish, octopus, and squid) match their surroundings and warn off attackers with their inspiring camouflage. Their skin has 18-30 muscle fibres that can rapidly change how much pigment they expose. Adapting a system for military use would include infrared camouflage coatings and invisibility covering (of increasing importance as more IR sensors are deployed on battlefields). By altering the material of gear, it also opens up other opportunities for enhancement, such as being able to regulate body temperature of the wearer.
