Quoted: The robot?s color-changing ability doesn?t have much in common with its biological inspiration?s, according to Douglas Weibel, a professor of biochemistry at the University of Wisconsin?Madison who is unaffiliated with the paper. The squid in the wild doesn?t use biochemical processes like fluid and air manipulation to create its color-changing effect. Rather, the animal uses an optical illusion to reflect light and blend in to whatever background it finds itself within. “It?s structural color, and I think that?s pretty hard to do,” Weibel says. “People know how to make iridescent structures, but I don?t know any really good examples of structured color.”
