Why nature is an engineer’s best inspiration

May 10, 2016

Have you ever flown on a plane? Or used Velcro to hold two things together? If so, you’ve benefitted from biomimicry, an approach to solving human problems through nature-inspired innovations.

The invention of Velcro, for instance, happened one day when a man brought his dog into the house after a walk. The man noticed some burrs stuck to the dog's fur, and began studying their design and the way the burrs clung to fur and clothing using tiny hooks. Soon after, he invented the first strip of Velcro. 

What would Styrofoam be like if it were made out of steel? Afsaneh Rabiei at North Carolina State University has been working for years to develop and perfect metal foams, the product of a manufacturing process that embeds hollow metal spheres in solid metal.

The resulting material is light, strong, heat, and radiation-resistant, and, when incorporated in a bulletproof vest, for example, capable of shattering bullets on impact without injuring the person wearing it.
