What are the examples of bionics?

1. A very strange small gas analyzer, which was successfully copied from annoying flies. It is installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin.

2. A radio positioning and ranging device: Scientists found that bats rely not on eyes, but on an echolocation system consisting of mouth, throat and ears. Because bats emit ultrasonic waves when flying, they can also detect ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device.

3. The color of colorful butterflies is abrupt, such as butterflies with double moon patterns, monarch butterflies with brown veins, especially butterflies with fluorescent wings. Later, it turned into gold, green and purple in the sun, and finally became blue. Scientists have brought great benefits to military defense by studying the color of butterflies. This paper points out that the color of butterflies is not easy to be found in flowers, and military facilities are covered with butterfly-like camouflage. So according to the same principle, people later produced camouflage clothes.

4. Bionic scientist Locke invented the electronic frog eye according to the principle and structure of frog eye. In modern warfare, the enemy may launch missiles to attack our targets. At this time, we can launch anti-missile to intercept each other's missiles, but the enemy may also send signals to disturb our sight in order to confuse us. On the battlefield, the true and false missiles launched by enemy planes, tanks and ships are changing rapidly. To defeat the enemy, it is necessary to distinguish the true and false missiles in time. By combining the eyes of the electronic frog with the radar, we can see the moving things keenly, but turn a blind eye to the static things, just like the eyes of the frog, tracking the real targets in flight sensitively and quickly.

5. People simulated the organs that jellyfish felt infrasound, and successfully designed an accurate "jellyfish ear" instrument. It consists of a loudspeaker, a vibrator for receiving infrasound waves, a transducer for converting this vibration into electric pulses and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360. When it receives 8 Hz- 13 Hz infrasound, the rotation stops automatically, and the direction indicated by the horn is the coming direction of the storm. Indicators can also tell people the intensity of the storm. This instrument can forecast storms 15 hours in advance. ?

6. According to the visual principle of frog eye, people have successfully developed an electronic frog eye. This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion; Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding.

Extended data:

Bionics is an ancient and young subject.

People study the principles of structure and function of objects, and invent new equipment, tools and technologies according to these principles, and create advanced technologies suitable for production, study and life.

The word bionics was formed by Steele in the United States in 1960 according to the Latin word "bios (meaning of lifestyle)" and the suffix "NLC (meaning of" nature "). This word was only used about 196 1 years ago. The function of some living things is far superior to that of any artificial machinery, and bionics is a subject to realize and effectively apply biological functions in engineering. For example, information reception (sensory function), information transmission (neurological function), automatic control system, etc. The structure and function of this organism give great inspiration to mechanical design. Examples of bionics can be cited, such as applying the body shape or skin structure of dolphins (which can prevent turbulence on the body surface when swimming) to the design principle of submarines.

For another example, flies are the disseminators of bacteria and are generally classified as pests, but their wings are natural navigators. Moreover, its eyes are a kind of "compound eyes", consisting of more than 3000 small eyes. People imitate it and make a "fly-eye lens". "Compound eye lens" is a new type of optical element, which has many uses. The "compound eye lens" is composed of hundreds or thousands of small lenses arranged in sequence. It can be used as a lens to make a "compound eye camera" and can take thousands of identical photos at a time. This kind of camera has been used for printing plate making and copying a large number of tiny circuits of electronic computers, which greatly improves the work efficiency and quality.

Bionics is also regarded as a discipline closely related to cybernetics, which mainly compares life phenomena with mechanical principles and studies and explains them.
