Blue Tarantulas May Help Humans Make Better Wide-angle Computer Displays

Blue Tarantulas May Help Humans Make Better Wide-angle Computer Displays | Biomimicry | Scoop.it

"At least 40 species of tarantulas come in shades of blue.  [...] To find out more about the "tarantula blue," researchers used different microscopy techniques to analyze tarantula hairs. They found that although these species share a shade of blue, tarantulas don't use pigments to produce it. Instead, the blue colors are produced thanks to nanostructures in the spiders' hair, which reflect blue light. And these nanostructures differ between species, the scientists found. Most importantly, however, these blue colors don’t change intensity or hue as the viewing angle changes. That's a big differentiator from the highly iridescent structural colors seen in most birds, butterflies, and beetles."

New Nano Materials Inspired by Bird Feathers Play with Light to Create Color

New Nano Materials Inspired by Bird Feathers Play with Light to Create Color | Biomimicry | Scoop.it

"Inspired by the way iridescent bird feathers play with light, scientists have created thin films of material in a wide range of pure colors — from red to green — with hues determined by physical structure rather than pigments.

Structural color arises from the interaction of light with materials that have patterns on a minute scale, which bend and reflect light to amplify some wavelengths and dampen others. Melanosomes, tiny packets of melanin found in the feathers, skin and fur of many animals, can produce structural color when packed into solid layers, as they are in the feathers of some birds. 

“We synthesized and assembled nanoparticles of a synthetic version of melanin to mimic the natural structures found in bird feathers,” said Nathan Gianneschi, a professor of chemistry and biochemistry at the University of California, San Diego. “We want to understand how nature uses materials like this, then to develop function that goes beyond what is possible in nature."

Butterfly-Inspired Building

Butterfly-Inspired Building | Biomimicry | Scoop.it

"The rare blue morpho butterfly is among the largest butterflies in the world and one of the most spectacular with its brown wings that suddenly turn iridescent blue. This amazing display happens when blue light reflects off the layers of microscopic scales on its wings. 3M scientists studied the butterfly to mimic this effect in a window film."

Limpet's Shell Could Inspire Next-gen Transparent Displays

Limpet's Shell Could Inspire Next-gen Transparent Displays | Biomimicry | Scoop.it

"..an MIT/Harvard study suggests that a specific type of limpet's shell may hold the key to transparent displays that require no internal light source. The mollusk in question is the blue-rayed limpet which, as its name implies, has bright blue stripes on its translucent shell. It is believed that these are used to make potential predators mistake it for a poisonous snail, which also has blue markings. The iridescent lines appear blue due to the fact that the shell material in those areas reflects the blue spectrum of incoming light, while absorbing other colors so that they don't drown out the blue."

Longhorn Beetle Inspires Ink to Fight Counterfeiting | Biomimicry | Scoop.it

"From water marks to colored threads, governments are constantly adding new features to paper money to stay one step ahead of counterfeiters. Now a longhorn beetle has inspired yet another way to foil cash fraud, as well as to produce colorful, changing billboards and art displays. In the journal ACS Nano, researchers report a new kind of ink that mimics the beetle’s color-shifting ability in a way that would be long-lasting and difficult to copy."

"The TED2014 conference kicks off today in Vancouver, marking the 30th anniversary of the event. The theme of this year's conference is "the next chapter," and each attendee will receive a sample of what could be the next chapter in anti-counterfeit technology. The TED2014 ID badges feature a small iridescent panel with a "30 years TED" logo. The image isn't a hologram, but is created by billions of nano-scale holes. The technology is inspired by the wings of the Morpho butterfly, and this is one of its first major real-world applications. The super-tiny holes reflect and transmit light in a distinctive way, making the logo easy to identify and hard to copy."

Smartwatch Uses Bio-ispired Mirasol Display Technology

Smartwatch Uses Bio-ispired Mirasol Display Technology | Biomimicry | Scoop.it

"The Mirasol display technology (developed by Qualcomm) is based on biomimetics - that is, technology that imitates nature. The natural phenomenon that makes a butterfly’s wings or a peacock’s feathers shimmer and give off their rich, striking colors is the same exact quality that drives how Mirasol displays generate color. How do butterflies and peacocks do it? Through microscopic structures on their wings and feathers they are each able to create truly vivid colors simply by causing light to interfere with itself. This "interference" is the reason the term "interferometric" comes into play."

Harnessing The Power Of Peacocks To Make Colorful Images

Harnessing The Power Of Peacocks To Make Colorful Images | Biomimicry | Scoop.it

"The gloriously colored, iridescent feathers of the male peacock aren't what they seem on the surface. They look that way largely because the feathers contain nanometer-scale protein structures that break up incoming light waves, recombine and reflect them as rich, vibrant colors. Scientists at the University of Michigan think they have a technology that emulates this process to display pictures without chemicals or electrical power. Eventually, the technology could replace the displays now used on smartphones, tablets, and computer screens, with strikingly high definition."

Electronic Paper Displays: Kindles and Cuttlefish: Biomimetics Informs e-paper Displays

Electronic Paper Displays: Kindles and Cuttlefish: Biomimetics Informs e-paper Displays | Biomimicry | Scoop.it

Both electronic paper (e-paper) and certain biological organisms share the need for adaptive, reflective surfaces to communicate information. The goal of each is to use numerous colors, textures, polarization, and contrast variations without optical losses in order to maximize and control (in an energy-efficient way) the desired physical appearance. Recognizing these display commonalities, researchers at the University of Cincinnati (Cincinnati, OH), the USA Marine Biological Laboratory (Woods Hole, MA), the Air Force Research Laboratory at Wright Patterson Air Force Base (Dayton, OH), and the Army Research Laboratory (Adelphi, MD) are attempting to merge the knowledge base of biomimetics used for biological adaptive coloration and appearance (with a focus on cephalopods such as squid, cuttlefish, and octopus) and synthetic reflective e-paper displays (such as Amazon’s Kindle and the Sony Reader) using a series of scientific metrics

Display Design and the Human Vision System

Display Design and the Human Vision System | Biomimicry | Scoop.it

"PenTile® technology is biomimetic, meaning it is designed to compliment the complex mechanics of the eye-brain system. As a simple example of eye mechanics consider how the eye utilizes the color blue. The eye has cone receptors that sense color and brightness, and discern patterns. These cones are sensitive to different wavelengths of color—primarily red, green, and blue. The blue cones detect mostly color (chroma) information, while the red and green cones do most of the work resolving images by discerning luminance, edges, and structural details of images, as well as contributing to color vision. The red and green cones are used independently, each cone seeing a "dot" of black and white—ignoring its color to produce high resolution luminance perception—and are used in opposition, comparing the amount of red versus green, to produce low resolution color perception.

 

The PenTile RGBW™ layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the red and green cones, while using the combined effect of all the color subpixels to present lower-resolution chroma (color) information to all three cone types. Combined, this optimizes the match of display technology to the biological mechanisms of human vision."
