But instead of color, these cells hold a tiny, thin piece of black rubber. A process that squeezes the rubber pieces causes them to appear flatter and wider.
When all these black spots are expanded at the same time, it looks like the skin is suddenly darkening. And just like the cuttlefish, the color change takes place in less than a second.
In the future, Rossiter hopes that by layering the cells, they can create material with multiple color changes or moving patterns.
How can it be used?
Military groups may find the material useful for camouflage. Hikers and bikers, though, will appreciate the ability to become suddenly bright, making themselves stand out for safety purposes. And who knows, "cuttlefish fashion" may someday be the latest thing on the runway.

lotus flower 蓮花,
德國用蓮花的葉子發明了防水的油漆- 德國波恩大學植物研究所所長威廉•巴特洛特及其領導的小組，在蓮花葉面上倒幾滴膠水，膠水不會粘連在葉面上，而是滾落下去，並且不留痕跡。經過努力，他發明了一項新技術，生產出表面完全防水並且具備自潔功能的材料。
