…we human beings, who have been trying to make things for only the blink of an evolutionary eye, have a lot to learn from the long processes of natural selection, whether it’s how to make a wing more aerodynamic or a city more resilient or an electronic display more vibrant… one of the most often-cited examples is Velcro, which the Swiss engineer Georges de Mestral patented in 1955 after studying how burs stuck to his clothes…
More than a decade ago, an MIT grad named Mark Miles was dabbling in the field of micro-electromechanical and materials processing. As he paged through a science magazine, he was stopped by an article on how butterflies generate color in their wings. The brilliant iridescent blue of the various Morpho species, for example, comes not from pigment, but from “structural color.” Those wings harbor a nanoscale assemblage of shingled plates, whose shape and distance from one another are arranged in a precise pattern that disrupts reflective light wavelengths to produce the brilliant blue. To create that same blue out of pigment would require much more energy—energy better used for flying, feeding and reproducing.
Miles wondered if this capability could be exploited in some way. Where else might you want incredibly vivid color in a thin package?
