About the Author: Jane Li. Shark skin microbiome resists infection. The Sort by. In the wild, blacktip reef sharks are often seen bearing wounds, but they rarely exhibit obvious signs of infection around the wounds. SWISS has become the first passenger airline in the world to adopt the new AeroSHARK aircraft skin technology co-developed by Lufthansa Technik and coatings manufacturer BASF. 2 of 5. This important organ is of a complex structure, a composite that is collagen fiber reinforced and pliant. Sharkskin is an advanced, full-thickness wound dressing that can be rapidly produced and customized at the point-of-care. They are ancient animals, honed by millions of years of evolution into sleek swimming and hunting machines. A material that mimics shark skin, covered with tiny ridges and groves, may help reduce the spread of bacteria in hospitals, a new study suggests. Interestingly, the numerical calculated results obtained show that the presence of biomimetic shark skin implemented on the vessels give about 3.75% reduction of drag coefficient as well as reducing up to 3.89% in drag force experienced by the vessels. Sharklet: A biotech startup fights germs with sharks. Shark Biomimicry: How Sharks Inspired Advanced Medical Technology. Technology Overview. Sort by. Shape-shifter in action. The shark skin denticles can flex at angles more than 40 degrees from its bodybut only in the direction of reversing flow (i.e., from tail to nose). The researchers found that by applying the skin to the entire fuselage and engines of a Boeing 777, they could reduce fuel consumption by 1.1%. Shibaura Institute of Technology Home. A 3D-printed material that gets its inspiration from shark skin can be used as an anti-bacterial coating in hospital settings. SURFACE TECHNOLOGY References Bechert, D.W., Hoppe, G., Reif, W.E. Inspired by the pattern of shark skin, Sharklet is the unique biomimetic technology that achieves antibacterial and antifouling activitie s t hrough microtopography on surfaces of Researchers have utilized the precision of 3D printing to accurately recreate the shark skin denticle structure. That led to his founding of Sharklet Technologies in 2007. Shark-skin-inspired riblets have been verified to provide drag-reduction effect up to 10% []. I n 1952, well before developmental biologists spoke in terms of Hoxgenes and transcription factors, or even understood DNAs structure, Alan Turing had an idea. shark skin texture. AeroSHARK, a surface film that mimics the fine structure of a sharks skin, is to be rolled out on A survey of the shark skin microbiome provides the first step toward understanding the remarkable resilience of shark wounds to infection. Sharklet has developed a product that keeps harmful bacteria from spreading on medical equipment like urinary catheters and endotracheal tubes. MicroTau CEO Henry Bilinsky will use the $5.6 million in seed funding to turbocharge the technology, which he says was inspired by "nature's functional surfaces". However, the patterned surfaces limited the growth of biofilm.

So, perhaps in the near future, common objects such as door knobs and bed rails of hospitals could be covered with a shark skin-inspired surface to prevent the mass spread of infection. Studying sharks: How their skin has evolved In the ocean, sharks are apex predators. High-technology swimwear, or tech suits, are scientifically advanced materials used for swimwear in competitive water sports such as swimming and triathlon.Materials of this type are normally spandex and nylon composite fabrics with features to reduce drag against the water.

MicroTau The animal's skin is being emulated in the design of energy-saving fans for air conditioners. Shark skin denticles geometry minimizes the turbulence of the water in micro scale. The fabrication of the bionic shark-skin coating with life-sized scale-like microstructure was presented in this paper. This artificial skin has the estimated potential to save US$20 billion fuel in fuel costs as well as reducing CO2 emissions by 92 million tonnes annually. The films surface structure consists of riblets that measure around 50 micrometers, imitating the properties of shark skin and optimizing the aerodynamic flow of the aircraft to produce a drag reduction and reduce fuel consumption. One recent advance in swimming technology was the introduction of "shark skin" swimsuits - tight-fitting suits designed to imitate a shark's unique, sandpaper-like skin. The bionic Shark Skin contours are complemented by innovative Aqua Twist sipes that disperse the water from the contact patch fast. In Mimicking shark skin to combat superbugs.

Later, as Brennan was developing ways to improve his panel coatings, another researcher caught a shark and sent Brennan a mold of its skin. Viewed under a microscope, the skin had a pattern of dips and ridges. The pattern looked strikingly similar to one that Brennans mathematical analyses suggested might work as an improved coating. Shark skin is an active skin, meaning it is very closely connected to the animals thrust producing muscles that enable its undulatory, or wave-like, movement. For better similarity with real shark skin and easy fabrication, researchers usually optimise the structures of shark-skin-inspired riblets [, ].

Nature is a great source of wisdom that we learn from to make breakthrough engineering technology. Drag reduction with shark skin technology: Shark skin coating boosts performance Riblets surface minimize drag Riblets have, similarly to shark skin, tiny grooves arranged longitudinally along the Have you ever touched shark skin? New RainSport 5 features enhanced Shark Skin Technology, improved mileage. Professor George Lauder has found that the rough surface of shark skin helps reduce drag and increase thrust as the animal swims. The primary Sharklet micropattern is very small about 3 microns tall and 2 microns wide. Not so fast. It can help reduce water resistance and the friction The optimised tread design leads to a higher mileage and an outstanding noise performance. In 2001, materials scientist Dr. Anthony Brennan observed that Galapagos Sharks are barnacle and algae-free due to the micro- topography of their skin. The light-designed denticle structure exhibits superior hydrophobicity and an antifouling effect as sharks do.
