Study Notes
- Biomimicry is a scientific practice where scientists and engineers examine and imitate aspects of the natural world to solve human problems.
Examples of Biomimicry
- A Swiss engineer examining sticky burrs on his dog.
- A Japanese engineer observing a kingfisher diving into water.
- American scientists studying geckos' ability to climb walls.
Velcro
- George de Mestral, a Swiss engineer, studied burrs that stuck to his dog's fur.
- He observed that the burr seed casings had microscopic hooked barbs that latched onto fibers.
- In 1941, de Mestral developed hook-and-loop technology called VELCRO.
- VELCRO consists of strips with tiny hooks and soft loops that attach together.
Bullet Trains
- Japan developed high-speed trains known as "bullet trains" in the 1960s.
- The trains caused a loud booming noise when emerging from tunnels at high speeds.
- In the early 1990s, Eiji Nakatsu sought to make bullet trains quieter and more efficient.
- Nakatsu, being an avid birdwatcher, observed kingfishers diving into water with minimal splash.
- He suggested shaping the front of bullet trains like a kingfisher's beak to reduce noise.
- The newly shaped trains reduced the boom sound when exiting tunnels.
- The long, thin shape of the kingfisher's beak influenced the shape of the new and improved bullet trains.
Gecko Feet
- Scientists are studying gecko feet to imitate them in future inventions.
- They have developed two new technologies based on the microscopic hairs (setae) on gecko feet.
- One invention will allow humans to climb walls.
- Another invention is a group of powerful adhesives that can hold heavy objects and are easy to remove without leaving any stickiness behind.
- The stripes on a gecko's toes are actually comprised of thousands of microscopic hairs called setae.
Nature as Inspiration
- Nature serves as a source of exploration and inspiration for humans.
- Biomimicry is another reason to observe the wondrous features of the living world.
