Biomimicry with Artificial Structural Colors

Biomimicry with Artificial Structural Colors | Communication design | Scoop.it

"Bright colors in the natural world often result from tiny structures in feathers or wings that change the way light behaves when it’s reflected. This structural color is respon­sible for the vivid hues of birds and butter­flies. Arti­ficially harnessing this effect could allow us to engineer new materials for appli­cations such as solar cells and chame­leon-like adap­tive camou­flage. Inspired by the deep blue colora­tion of a native North American bird, Stellar’s jay, a team at Nagoya Uni­versity reproduced the color in their lab, giving rise to a new type of arti­ficial pigment. “The Stellar’s jay’s feathers provide an excellent example of angle-inde­pendent structural color,” says Yukikazu Takeoka, “This color is enhanced by dark materials, which in this case can be attri­buted to black melanin particles in the feathers.”

Flight Videos Deconstructed: The Patterns Wings Trace in Flight

Flight Videos Deconstructed: The Patterns Wings Trace in Flight | Communication design | Scoop.it

Although many animals take flight, they don’t do it in exactly the same way. That’s what Eleanor Lutz’ exceptional animated infographic shows us. She’s taken the flight patterns of 5 different species – egyptian fruit bat, dragonfly, Canada goose, hawk moth and hummingbird – and used Youtube videos to give us a look at how their wings move.

 

“I found slow-motion videos of five flying species, and mapped out specific points on the wings during one wingbeat. I ended up with 15 frames per wingbeat, and I connected every frame using imaginary curves that went through all of the 15 mapped points.”


Lutz is the first to point out that this isn’t a scientific exercise that draws firm conclusions – it’s more a beautifully artistic pursuit. You’ll definitely want to take a closer look on her blog, and at the other fascinating scientific animations.
