What are the inventions of bionics?

1, submarine shape: submarine shape imitated the whale, can reduce the resistance of traveling in the water, and can reduce the noise, while increasing the ability to hide; submarine's working principle is imitated the swim bladder of the fish to work.

2. Electronic frog's eye: According to the visual principle of frog's eye, electronic frog's eye was invented. The electronic frog's eye can accurately recognize the specific shape of the object like the real frog's eye. The electronic frog's eye into the radar system, radar anti-jamming ability greatly improved. This kind of radar system can quickly and accurately identify specific shapes of airplanes, ships and missiles. In particular, it is able to distinguish between real and fake missiles and prevent them from being mistaken for real.

3, radar: bats are the use of "ultrasound" in the night navigation. Bat's throat sends out a more than human ears can hear high-frequency sound waves, this sound wave along the straight line propagation, an object will quickly return to the bat with the ear to receive the return of ultrasound, so that it can make accurate judgments to guide the bat flight. And radar is the use of this feature, scientists with the help of bionic principle, human beings according to the bat's echolocation system to create a radar.

4, "compound eye" digital camera: scientists inspired by the structure of the compound eyes of bees and flies, invented a "compound eye" digital camera. This camera hemispherical arrangement of 180 microscopic lenses, so that it has a 160-degree field of view, able to focus on different depths of the object at the same time. While the human eye and all cameras use a single lens to focus light onto a light-sensitive tissue or material substance, an arrangement that produces high-resolution images, the compound eye offers the distinct advantage of producing a panoramic view that gives a remarkable sense of depth.

5, aircraft: the invention of the aircraft from the human desire to fly and the study of birds, in recent times due to the development of aerodynamics as well as mechanics, people gradually understand the principle of bird flight, is due to the shape of the bird's wings, the speed of airflow through the upper surface of the wing is faster than that through the lower surface of the velocity, resulting in the lower wing surface by the upward pressure of the airflow is greater than that of the upper surface by the downward pressure of airflow, this pressure difference is the lift. This difference in pressure is the force of lift, and from this the airplane was built.
