The Sharklet Technology

The Sharklet Technology | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
Healthcare professionals use a variety of tools to combat dangerous infections. These include: Personal maintenance – Washing your hands, using hand sanitizer, avoiding contact with eyes and face Antibiotics – Powerful medications that kill bacteria Chemicals – Sprays and solutions meant to sterilize surfaces These precautions are effective and work most of the time – but each has a shortfall. The passenger next to you on the train is not as diligent with hand washing as you would hope. The door handle has all sorts of bacteria on the surface, even between cleanings. Antibiotics are effective, but eventually some strains of bacteria become resistant to antibiotics. Using chemicals comes with a heavy cost, between their environmentally unfriendly manufacturing and dangerous side effects. Sharklet is the solution. The antibacterial properties of Sharklet are not a result of harsh chemicals or antibiotics – they are purely structural. This is due to the unique shape and configuration of the Sharklet micropattern.

Sound-proof metamaterial inspired by spider webs

Sound-proof metamaterial inspired by spider webs | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

Spider silk is well-known for its unusual combination of being both lightweight and extremely strong—in some cases, stronger than steel. Due to these properties, researchers have been developing spider-silk-inspired materials for potential applications such as durable yet lightweight clothing, bullet-proof vests, and parachutes. But so far, the acoustic properties of spider webs have not yet been explored. Now in a new study, a team of researchers from Italy, France and the UK has designed an acoustic metamaterial (which is a material made of periodically repeating structures) influenced by the intricate spider web architecture of the golden silk orb-weaver, also called the Nephila spider.

KARLSRUHE INSTITUTE OF TECHNOLOGY - PI 2016 - Nanofur for Oil Spill Cleanup

KARLSRUHE INSTITUTE OF TECHNOLOGY - PI 2016 - Nanofur for Oil Spill Cleanup | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

Some water ferns can absorb large volumes of oil within a short time, because their leaves are strongly water-repellent and, at the same time, highly oil-absorbing. Researchers of KIT, together with colleagues of Bonn University, have found that the oil-binding capacity of the water plant results from the hairy microstructure of its leaves. It is now used as a model to further develop the new Nanofur material for the environmentally friendly cleanup of oil spills. (DOI: 10.1088/1748-3190/11/5/056003)

Des chercheurs de l'Université de Harvard ont conçu une raie-manta artificielle qui fonctionne grâce à des muscles inspirés du rat.

Pour concevoir un nouveau système particulièrement adapté aux milieux marins, les chercheurs du laboratoire de bio-ingéniérie de Harvard se sont donc inspirés d’un animal réputé pour l’originalité de mode de locomotion : la raie. Ils ne sont pas les seuls à avoir eu cette brillante idée puisque en 2013, le département de mécatroniques du MIT testait déjà un prototype de robot. “Ce que nous faisons, c’est d’utiliser les outils de la robotique pour comprendre le cœur” a indiqué Kit Parker. Car pour concevoir ce petit être artificiel, ce physiologiste cardiaque s’est inspiré du fonctionnement musculaire du rat. Il espère d’ailleurs à terme réutiliser les techniques développées pour ce modèle et les appliquer sur des cœurs artificiels humains.

Saving precious water with nanoscale ingenuity

Saving precious water with nanoscale ingenuity | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
(Nanowerk News) Managing scarce water resources is problematic for many Middle East countries, and forecasts predict a more straitened situation ahead. Desalination plants are one way to manage water shortages, as more than two-thirds of the world’s desalination capacity is in this region, but processing seawater has enormous energy and environmental costs. Other approaches need to be developed to achieve sustainable growth.
Over the past seven years, Peng Wang and colleagues from the King Abdullah University of Science and Technology (KAUST) Biological and Environmental Science and Engineering Division, Saudi Arabia, have been looking for answers to these grand challenges by turning to very small science. The team specializes in producing materials and surfaces that purify, distill and catch water molecules with remarkable efficiency thanks to nanoscale techniques, many inspired by ingenious biological tricks.

Natural photosynthesis with artificial molecules

Chemists from the Universities of Basel and Zurich in Switzerland have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules. Their results have been published by the journal Angewandte Chemie ("Light-Driven Electron Accumulation in a Molecular Pentad").
Green plants are able to temporarily store electric charges after the absorption of sunlight by using a so-called molecular charge accumulator. The two research teams were able to observe this process in artificial molecules that they created specifically for this experiment.

Biomimétisme : Un robot tisse une somptueuse canopée au musée Victoria & Albert | Humanoides.fr | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it
L’idée étant de s’inspirer des structures en fibres de la nature pour concevoir des structures artificielles à la fois robustes et légères. La canopée n’est ainsi constituée que de deux matériaux, celui qui habite la toiture et celui que l’on trouve dans la structure. Les deux variantes sont toutes deux constituées de fibres de verres transparentes et de fibres de carbone. Exit les moules et autres processus de fabrication complexes. Ici, c’est le robot qui s’est chargé du tissage, réduisant drastiquement les pertes de matériaux. Pour concevoir chaque cellule de la canopée, le robot tisse les fibres de verres sur un cadre fait de fibres de carbone. Le processus étant entièrement numérisé, il est très facile pour les ingénieurs de varier la forme, la densité et l’orientation des cellules selon leur bon vouloir et donc d’adapter la structure générale au fil du temps et de l’espace. Avec ce matériau composite, la structure ne pèse que 9 kg au m².

Zipp 454 NSW wheels take design cues from whales | VeloNews.com

Zipp 454 NSW wheels take design cues from whales | VeloNews.com | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

For the 454, Zipp looked to humpback whales and, specifically, the lumps on the leading edges of their pectoral fins. Called tubercles, these protrusions make humpbacks more agile by keeping water attached to their flippers when they turn. In the same way that a plane can stall when air separates from the wing during high-speed maneuvers, uncontrolled turbulence over a whale’s flipper makes turning more difficult. Tubercles keep the water attached as it flows past. Aircraft designers have known about these benefits for years. A lot of airplane wings have small fins near their leading edges, turned at slight angles to the wind. These “vortex generators” disrupt airflow in a way that provides better lift and stability.

The nanostructured cloak of invisibility

The nanostructured cloak of invisibility | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

Researchers at the Max Planck Institute for Intelligent Systems took a page out of the design book for moth cornea. The corneas of these mostly nocturnal insects reflect almost no incoming light. There is no glow of light bouncing off the moth's eyes to betray their presence to potential predators. Less reflected light also means that moths are able to use practically all the scarce night-time light to see. This magic from the world of insects inspired scientists to try the same tactics for the design of optical components. Like the corneas of moths, the components must allow light to pass through while light reflection is of little use. So far, component designers apply anti-reflective coating to lenses, display screens, monitors and laser components. However, these coatings have disadvantages. Most of them work only in a narrow wavelength range, and they produce lens errors dependent on the angle of light incidence. Read more: The nanostructured cloak of invisibility

Une équipe de chercheurs du MIT s'est inspirée de la méthode d'isolation qu'utilisent les castors et les loutres des mers pour développer des combinaisons de surf plus performantes. Ces petits mammifères semi-aquatiques savent restés au chaud tout en conservant leur agilité. Deux caractéristiques clés pour une combinaison. Comment rendre les combinaisons des surfeurs plus isolantes sans entraver leurs mouvements ? Pour résoudre cette problématique, le fabricant de combinaison Sheico Group, s'est rapproché d'une équipe de chercheurs du MIT. Ces derniers se sont inspirés de la nature pour proposer une réponse pertinente.
Alors que les baleines utilisent leur épaisse couche de graisse pour se protéger du froid, d'autres mammifères plus petits et semi-aquatiques, comme le castor et la loutre des mers, utilisent leur fourrure très dense pour capturer des bulles d'air chaud et s'isoler du froid.

Taking a clue from jellyfish and squids that quickly alter their appearance via muscle-controlled morphology changes in their bodies’ surface structures, researchers have designed polymeric materials that change appearance reversibly in response to mechanically induced folds and deformations (Nat. Commun. 2016, DOI: 10.1038/ncomms11802). The animals exploit their color-changing abilities for camouflage and safety purposes. Scientists could use the new synthetic materials for those applications or as mechanical sensors, optical switches, and color-changing smart windows.

Getting a grip on mussel adhesion - A*STAR Research | Biomimétisme, Biomimicry, Bioinspired innovation | Scoop.it

The Asian green mussel (Perna viridis) anchors itself underwater by timed secretion of adhesive proteins from threadlike foot extensions, a team of researchers in Singapore finds1. Lab experiments and computer simulations reveal that an especially long sticky protein acts as a primer — first catching the surface and repelling water molecules to make way for two proteins that form the final adhesive pad. The discovery could lead to new submersible glues or improved paints to prevent biofouling on ship hulls and drilling platforms.
