Designed By Mother Nature
Developing a new technology from scratch is a complex and time consuming business, so wouldn't it be handy if scientists had a pre-existing blueprint at their disposal? As it happens, they do, and fortuitously it exists all around us: nature. And using nature as your template provides the added bonus of not having to worry about pesky patents. The science of copying nature, known as biomimetics, is not altogether new - think radar, Velcro and da Vinci's flying machines - but it is garnering increasing attention, with anything from the biomechanics of frog legs, to the sensing ability of rat's whiskers, being used as a basis for new inventions...
