how burdock fruits inspired the invention of the hook and loop fastener
Hook and loop fastener The original hook-and-loop fastener was conceived in 1941 by Swiss engineer George de Mestral.[1][2][3] The idea came to him one day after returning from a hunting trip with his dog in the Alps. He took a close look at the burrs (seeds) of burdock that kept sticking to his clothes and his dog's fur. He examined them under a microscope, and noted their hundreds of "hooks" that caught on anything with a loop, such as clothing, animal fur, or hair.[4] He saw the possibility of binding two materials reversibly in a simple fashion if he could figure out how to duplicate the hooks and loops.[1][3] Hook and Loop is viewed by some like Steven Vogel[5] or Werner Nachtigall[6] as a key example of inspiration from nature or the copying of nature's mechanisms (called bionics or biomimesis).
