Sometimes called Biometrics, Biomimicry is a way to copy nature’s patterns, systems and processes in order to design better earth sustainable ways to solve human problems.
An example of this is the artificial leaf. Scientists have developed a design for an artificial leaf that can produce hydrogen from sunlight and water through the process of photosynthesis. Hydrogen fuel cell technology is expensive. So using sunlight as the green plants do, could help to wean us off fossil fuels using renewable energy sources that don’t produce carbon dioxide.
Another example is seashells. The strength of sea shells found on the beach was the inspiration for scientist now developing extremely strong ceramic material for things like bone replacement. They have produced materials that reduce the brittleness and that naturally reduces cracks.
Velcro is probably one of the most famous examples of biomimicry. Velcro was invented by George de Mestral in 1941 after he removed burrs from his dog and decided to take a closer look at how they worked. The small hooks found at the end of the burr needles inspired him to create Velcro. The V formation of flying birds, long used by the military, now have scientists studying a scenario where jets from West Coast airports meet up and fly in formation to their East Coast destinations. By flying in a V-shape with planes taking turns in front as birds do, the researchers think aircraft could use 15 percent less fuel compared to flying alone.
Researchers are also working on developing paints and coatings for ships, airplanes, submarines and wind energy plants that are based on the texture of the skin of sharks. There are hundreds, even thousands of studies being done, all looking to nature for the answers.
Emulate nature and save the planet while producing better products? Sounds good! As Einstein said, “Look deep into nature, and then you will understand everything better.”
