It’s surprising what we can learn from nature. Peter Forbes’ 2005 book, The Gecko’s Foot details a number of bio-inspired innovations. Perhaps the most well-known is the lotus effect, the self-cleaning property of the lotus plant. By studying this plant, botanists and nanotechnologists have worked with engineers to manufacture self-cleaning glass, new types of solvents and other materials, which can “self-clean”. As the father of a 8-month old, I’d put in a request for spit-up friendly shirts!
