Traditionally, military camouflage is designed around fixed disruptive colouration patterns for a specific environment and geometry, and as a result, is only effective in a particular location where the background does not change and the object is stationary.[1c] However, recent developments in military research have focused upon the design and implementation of new methods to conceal military hardware from both visual and thermal automatic target recognition. As a source of inspiration, cephalopods (octopus and cuttlefish) are of particular interest due to their ability to change both their colouration camouflage pattern, via chromatophores, and also their geometrical shape, through the use of skin papillae.
Origami and kirigami design principles, whereby folded lines (with or without bonding or cutting) create localised regions of out-of-plane deformation, offer considerable potential for deployable geometries employing fibrous materials.
We used a silicone elastomer and paper reinforcement to fabricate soft active camouflage cells.
