"To build more aerodynamic machines, researchers are drawing inspiration from an unlikely source: the ocean. A team of evolutionary biologists and engineers at Harvard University, in collaboration with colleagues from the University of South Carolina, have shed light on a decades-old mystery about sharkskin and, in the process, demonstrated a new, bioinspired structure that could improve the aerodynamic performance of planes, wind turbines, drones and cars."

A biological material that has existed for millions of years may find new applications in modern electronics. A team of scientists from UC Santa Cruz, the University of Washington, and the Benaroya Research Institute at Virginia Mason discovered that shark “jelly” is the highest proton conductive biological substance ever found, according to GizMag. In plain English, that means the material is extremely good at detecting weak electrical signals from great distances away — something that scientists and engineers believe could be useful in future sensor design.

"Sharks have tough skin that is worthy of biomimicry by nanotechnology designers and engineers. New coatings, textiles and other technologies that mimic the special biological properties of shark skin have been developed in recent years and many more such innovations are emerging across multiple industries."

In its never-ending quest to develop more aerodynamic, more fuel-efficient aircraft, the aviation industry believes the ocean's oldest predator, the shark, could hold the key to cutting energy consumption.

A whale’s skin is easily glommed up with barnacles, algae, bacteria and other sea creatures, but sharks stay squeaky-clean. Although these parasites can pile onto a shark’s rippled skin too, they can’t take hold and thus simply wash away. Now scientists have printed that pattern on an adhesive film that will repel bacteria pathogens from hospitals and public restrooms.

The growing science of biomimicry focuses on what humanity can learn from the world, and Airbus engineers are learning quite a lot about efficient solutions for aircraft design that nature has spent millions of years refining.

"Scientists have been trying to unlock the secrets of shark skin for more than 50 years. The key to sharks' hydrodynamic prowess lies in how the rigid, tooth-like structures that coat their flexible skin change the flow of water as sharks swim forward – but attempts to quantify this effect have fallen short. After all, it's tough to fabricate a material that closely mimics shark skin, a marvel of Nature honed over the 400 million years that sharks have sleuthed the seas."

Mimicking is a great way of fast-forwarding the design process. It is a never ending process.

"Harvard scientists say that they've managed to replicate one of the most fascinating organs of the animal kingdom in a lab. Their finely-detailed synthetic shark skin could make some of the fastest underwater robots around, and maybe even one day grace human wetsuits or the hulls of ships."

"Forget chemicals or pills in the fight against nasty bacterial infections. Entrepreneur Mark Spiecker is betting that the secrte lies with sharks. Those fast and carnivorous fish just happen to have microscopic textures on their skin that make them highly resistant to barnacles, algae and, surprisingly, most human bacteria."

Industrial design student Anthony Reale has borrowed from the basking shark to create ‘strait power,’ a water-powered turbine generator that tests have shown is 40 percent more efficient than current designs.
