Engineered by humans, inspired by nature » Scienceline | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
Inventors have been exploring biomimicry as early as the Renaissance era when Leonardo Da Vinci sketched out a bat-shaped wing contraption for human flight, called an ornithopter. Engineers take what they see in the natural world and integrate it into new technologies.

Entire research institutes and education programs dedicated to biomimicry are working on technologies that maximize efficiency and cut manufacturing costs. The Korea Advanced Institute of Science and Technology made cost efficient LED lights for flat screen televisions and mobile phones that emulate the glow of fireflies; the Pacific Northwest National Laboratory in Washington developed hydrogen-pumping fuel cells for powering buildings and cars, which copy natural enzymes found in microorganisms.

Biomimetic Filters Recover Clean Water From Sludge

Biomimetic Filters Recover Clean Water From Sludge | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
San Jose-based zNano is getting attention for what could be a breakthrough technology designed to recover clean water from sludge.

The startup's molecular filtration technology operates "on a scale that wasn't feasible before — the small scale," Silicon Valley Business Journal reported.

"In the past, that kind of reclamation was only economical at large and expensive plants, and the environmental benefit produced from recycled water was often canceled out by the large amount of energy used to produce it," the report said.

ZNano targets its technology to small businesses such as laundromats.

"With zNano, recycled water is both cleaner and cheaper than most other sources of water. The best part about zNano's system is by recycling water for non-potable uses like laundry, car washes, and irrigation, we can avoid concerns about drinking recycled water," the company says.

Ecosociable.com recently included zNano on a list of "10 new biomimetic applications in clean technology."

"zNano’s water filters mimic the structure of cellular water membranes to transform polluted water into water 70% cleaner than tap water," the report said.

Squid-skin displays bring us closer to biotech camouflage (Wired UK)

Squid-skin displays bring us closer to biotech camouflage (Wired UK) | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

Cephalopods are curious creatures, able to flex their bodies into nifty shapes and camouflage themselves from sight. Unsurprisingly, they have also been inspiring biomimicry-led designs for years because of this. This month a paper to be published in Nature Communications deals with their flexi-strechy skills and describes how man can now engineer an elastic film that lights up when stimulated using electricity. Meanwhile, a team of US material scientists has opted to create a new method of colour display using a technique they say will get us that much closer to the holy grail of cephalopod biomimicry studies: camouflaging "squid skin" that morphs into background shades automatically, (otherwise known as a metamaterial).

A fascinating new programme highlights how new materials are being manufactured that can actually heal themselves. From ByteSizeScience – “Our latest episode explores materials that mimic the human skin’s ability to heal scratches and cuts. For a first-hand look at self-healing plastics, we visited the lab of Nancy Sottos, Ph.D., professor of engineering at the University of Illinois at Urbana-Champaign. Inspired by human skin, the plastics repair themselves by “bleeding” healing agents when they are cut or scratched. This research offers the promise of cell phones, laptops, cars, and other products with self-repairing, longer-lasting surfaces.”

Biomimicry of butterfly wings for more powerful solar cells | RobAid | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
The discovery that butterfly wings have scales that act as tiny solar collectors has led scientists in China and Japan to design a more efficient solar cell that could be used for powering homes, businesses, and other applications in the future. The researchers turned to the microscopic solar scales on butterfly wings in their search for improvements. Using natural butterfly wings as a mold or template, they made copies of the solar collectors and transferred those light-harvesting structures to Grätzel cells.Laboratory tests showed that the butterfly wing solar collector absorbed light more efficiently than conventional dye-sensitized cells. The fabrication process is simpler and faster than other methods, and could be used to manufacture other commercially valuable devices, the researchers say Wings taken from two species of butterfly were used as inspiration for their work, one is Papilio paris Linnaeus (subfamily Papilionidae of the family Nymphalidae), the other is Thaumantis

Nature has much to teach us about efficient use of energy. Take the bar tailed godwit, for example, which manages to fly, during his migration from Alaska to New Zealand, 10,000 km non-stop, in 10 days with a weight of 1kg. Engineers in various industries are turning to nature for inspiration as they try to design products with better performance and lower energy consumption.

In three short examples we show how paying more attention nature can save money in aviation, housing and shipping.

Watch the first steps of a robot inspired by stick bugs

Watch the first steps of a robot inspired by stick bugs | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
They grow up so fast, don't they? It was just a few years ago that HECTOR the stick bug robot was little more than a twinkle in Bielefeld University's eye, and it's already taking its first steps. Okay, so this isn't quite a tear-jerking moment, but it's still an important achievement in robotics. As you'll see in the video below, all of HECTOR's six insect-like legs move independently while reacting to unexpected changes in terrain. They shift to maintain balance on slippery ground, and raise themselves above small obstacles the moment they sense resistance.

HECTOR is just a proof of concept for now, so he won't be crawling outside of a lab any time soon -- probably a good thing, since he doesn't have eyes. Bielefeld already has a prototype with two cameras and "feelers," though, so there's a real possibility that you'll see this machine get around on its own by the time a planned 2017 upgrade arrives. If everything goes smoothly, this project could pave the way for autonomous cargo haulers, extraterrestrial rovers and other robots that can't always count on a stable footing

Les chats apprennent aux robots à retomber sur leurs pattes

Les chats apprennent aux robots à retomber sur leurs pattes | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

Bientôt, les robots sauront retomber sur leurs pattes ! Des chercheurs de l’Université Georgia Tech ont analysé la façon dont les chats réagissaient lors d’une chute pour pouvoir l’appliquer aux robots.

Dans une publication, les chercheurs de l'université Georgia Tech ont présenté un algorithme qui optimise la planification de la trajectoire holonome - qui peut effectuer indépendemment deux translations et une rotation - inspirée par le chat qui tombe. Il permet d'orienter un robot articulé, grâce à des changements de configuration, pour prendre une position lui permettant de réduire l’impact à l’atterrissage.
Damped spring LE SYSTEME MASSE-RESSORT AMORTI

L'amortissement d'un système se traduit par l'atténuation des mouvements de celui-ci par la dissipation de l'énergie qui les engendre.

« Ce n’est pas la chute qui vous tue mais l’arrivée brutale à la fin de celle-ci », explique le professeur Kareen Liu, agrégé à l'Ecole d'informatique interactive de Georgia Tech. L'un des facteurs les plus importants, et qui détermine les dégâts causés par la chute, est l'angle d'atterrissage. Ce contrôleur pilote plus exactement le système Masse-Ressort amorti du robot (voir encadré) pour réduire l’ampleur des efforts lors du contact.

Biomimicry Run Amok: New Micro Air Vehicles Can Swarm Like Bees

Biomimicry Run Amok: New Micro Air Vehicles Can Swarm Like Bees | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
We’ve been hearing a lot about robot swarms, biomimicry, and drones the size of insects, so it was only a matter of time before swarms of tiny flying robot drones hit the skies. Called micro air vehicles or micro aerial vehicles (MAVs), the latest development is an upcoming test of bee-inspired mechanical critters by the US Army at Fort Benning, Georgia.

The Army’s interest in high tech apiculture is coming from a need to increase a Soldier’s situational awareness of building interiors during urban operations, so don’t look for these biomimicry MAVs to sport tiny little bee stingers — yet. In any case, we’re more interested in the potential for clean tech applications.

Giant clams' shiny shells may inspire solar power tech

Giant clams' shiny shells may inspire solar power tech | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
Brilliant shades of blue and aqua coat the iridescent lips of giant clams, but these shiny cells aren't just for show, new research finds. The iridescent sheen directs beams of sunlight into the interior of the clam, providing light for algae housed inside.

In a symbiotic return, the algae use that sunlight to power photosynthesis, resulting in energy for the giant clam. "It ends up being a large part of the energy budget of the clams," said study researcher Alison Sweeney, an assistant professor of physics and astronomy at the University of Pennsylvania.

Essentially, the oversize mollusks, which can measure more than 4 feet (1.2 meters) long, have a natural solar energy system hiding in their shells.

Qualcomm Mirasol display for color e-readers inspired by butterflies | RobAid

Qualcomm Mirasol display for color e-readers inspired by butterflies | RobAid | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
Qualcomm MEMS Technologies new Mirasol display is the first full color, video-capable display on a prototype e-reader, built on the concept of the iridescence of butterfly’s wings. The inspiration for Mirasol’s engineering came from nature’s most vividly colored creatures: the cerulean wing of a butterfly, the ruby throat of a hummingbird, and the rainbow flash of a tropical fish. The crystals reflect light at different angles, causing light waves to interfere with one another, which we see as changing or iridescent colors. Scientists call it structural color, as opposed to color by pigmentation. Mirasol technology, formally known as interferometric modulation (IMOD), uses electrically charged, tiny flexible membranes overlaid onto a mirrored surface to mimic the reflective properties of biological crystals. Mirasol displays require virtually no illumination or backlighting, a power sucking requirement of LCD screens, resulting in significant energy savings. Pike Research estimates

Sea Creatures Inspire Bottle Design

Sea Creatures Inspire Bottle Design | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

Nature is full of elegance. Sometimes that elegance, to human eyes, also appears as great beauty. But being beautiful isn’t (except maybe when attracting mates) the purpose of that elegance. Nature is elegant in its designs because that elegance has a function.

Carlos Rego, a designer with Logoplaste Innovation Lab in Portugal, has found functional patterns in nature that have added beauty to his designs for something as utilitarian as a bottle. Those same patterns added strength while decreasing weight — and therefore material — from those bottles. And recently, the organisms that inspired the company’s latest design may also benefit from it. This story is about learning from nature how to minimize materials while still providing needed strength, how to cooperate, and how to design to make products that are not just less harmful to life, but are also restorative

Les Biofaçades : Des algues fournissent en énergie nos bâtiments | Inspire Institut, réconcilier développement économique et biosphère. | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

L'Agence d’architecture autrichienne Spitterwerk a mis au point ce concept de façade à base d'algues. Ce projet innovant baptisé BIQ a été construit en Allemagne, dans la ville de Hambourg. Le début du chantier remonte à 2011 et l'immeuble a été livré récemment.

Les façades bio-adaptives de ce bâtiment passif sont constituées de micro-algues intégrées dans les parois. Le BIQ permet ainsi à un bâtiment d’accéder à une certaine autonomie énergétique. Comment ? Grâce au recours à l’énergie solaire et à la photosynthèse ainsi qu’au recyclage de l’énergie solaire.

Des volets bio-réactifs constitués de micro-algues habillent l'immeuble. Ce système permet un développement rapide des algues, en leur offrant les conditions favorables à leur survie. Il ne reste plus alors qu'à capter l’énergie thermique qui émane des algues. Cette énergie sert ensuite à l’alimentation en énergie de l'édifice. La présence des algues en façade et sur les volets permet en outre de créer de l’ombre, améliorant le confort intérieur.
