What animals did humans get inspiration from and invented?

The inspirations and inventions that humans get from animals are:

1. Giraffe's muscles around blood vessels are very developed, which can compress blood vessels and control blood flow. The skin and fascia of giraffe's legs and whole body are very tight, which is beneficial to the upward blood return of lower limbs. Inspired by this, scientists have developed a flight suit-"anti-Dutch suit". The anti-load suit is equipped with an inflator. With the increase of spacecraft speed, the anti-load suit can be filled with a certain amount of gas, thus exerting a certain pressure on blood vessels and keeping the blood pressure of astronauts normal.

2. The kangaroo thigh root of off-road vehicle has good elasticity, which inspires people to refer to the shock absorption design of off-road vehicle to increase elasticity. So, in fact, off-road vehicles are like kangaroos.

3. The nose of bionic robot elephant can not only roll up the whole tree, but also pick up peas on the ground, which combines strength and dexterity. German engineers developed a bionic manipulator according to the characteristics of elephant nose. This manipulator consists of three hollow pipes. Three different pipes can be inflated and deflated to expand and bend. At the end of the mechanical nose, there is an extra hose to complete the fine grasping action.

4. Velcro is also called shackle or velcro. George de Mestral, a Swiss engineer, found burdock burrs on his trousers and pet dog. He found that the small hook on the seed could make it hang on other animals. It took George de Mestra more than ten years of experiments to perfectly reproduce this kind of hook.

5. Sonar 19 15, French physicist paul langevin invented a system that uses sound waves and echoes to locate underwater objects, which is what we call sonar technology today. This is based on the navigation, predation and search technology of bats and dolphins.

6. scotch tape Gecko in nature can climb to the surface completely by the fine bristles at the bottom of the toes. Richard Gurley Drew tried all kinds of adhesives, trying to find a way to remove the adhesive tape without leaving a trace, which eventually led to the emergence of scotch tape.
