Biomimicry

airfoil

George de Mestral

Biomimicry [bahy-oh-mim-ik-ree] is the imitation of biological systems in human technology. Living organisms have evolved well-adapted structures and materials over geological time through natural selection. Nature has solved engineering problems such as self-healing, environmental exposure tolerance, hydrophobicity (waterproofing), self-assembly, and harnessing solar energy.

One of the early examples of biomimicry was the study of birds to enable human flight. Although never successful in creating a ‘flying machine,’ Leonardo da Vinci (1452–1519) was a keen observer of the anatomy and flight of birds, and made numerous notes and sketches on his observations as well as designs of rudimentary ornithopters based on bats. The Wright Brothers, who succeeded in flying the first heavier-than-air aircraft in 1903, derived inspiration from observations of pigeons in flight. Their airfoil was based on a design by German ‘Glider King’ Otto Lilienthal who published ‘Birdflight as the Basis of Aviation.’ Velcro, another famous example, was inspired by the tiny hooks found on the surface of burs.
