Bristol Researchers Create Artificial Skin That Camouflages At Switch Flick
Developing bio-inspired technology is the biggest trend in the research field. A team of scientists from the Department of Engineering Mathematics at Bristol University have made it possible to develop artificial skin that transforms at a simple switch flick. Inspired from the squids, the marine animals which have a bilateral body, a prominent head, and a set of tentacles, the Bristol researchers designed a smart materials system that mimic biological patterning. Made out of electroactive dielectric elastomer, the artificial skin is able to copy the action of biological chromatophores, the tiny pigmented cells embedded on a squid's skin that can expand and contract to change skin's colour and texture.

The smart materials system uses simple local rules in artificial chromatophore cells for dynamic pattern generation. It operates by sensing their surroundings and manipulating their change. By modelling sets of artificial chromatophores in linear arrays of cells, the researchers tested if the system could produce a variety of patterns.
Much to their success, the system could mimic complex dynamic patterning seen in real cephalopods such as the Passing Cloud display, which is when bands of colour spread as waves across the skin.
The team hopes to use their technology to build cloaking suits as well as create dynamic illuminated clothing.
