What animals did people get inspiration from?

What animals did scientists get inspiration from and what did they invent? Birds fly in the sky: they make all kinds of flying machines.

Bees build nests: various hexagonal honeycomb structural plates.

Every dragonfly has a slightly heavier point at the end of its wing than its surroundings, which is the key to prevent its wings from shaking. Aircraft designers study the flight methods of flies, mosquitoes, bees, etc. , and created many new aircraft with various excellent performances.

Whale: the shape is ideal "streamline", and "streamline" has the least resistance in water. Later, engineers imitated the shape of whales, improved the design of the hull and greatly increased the speed of the ship at the stern.

Eggshell: it can evenly distribute the pressure to all parts of the eggshell. According to the characteristics of this "thin shell structure", architects have designed many buildings that are both light and material-saving.

Kangaroo: A jumping cross-country car.

Shell: A tank with a solid shell ...

Fish swimming in the water: learned to swim and invented the submarine.

One-piece shark suit: the first generation shark suit imitates the skin of sharks, and some rough dentate protrusions are designed on the swimsuit to effectively guide the water flow, tighten the body and avoid skin and muscle vibration. The second generation of shark clothing has added some new highlights and a material called "elastic skin", which can reduce people's resistance in water by 4%.

The tortoise carries a tortoise: a tank with a rotating turret.

Let the blind see the light: After implanting tiny bionic retina, three blind patients not only saw flashing or moving light spots, but even successfully distinguished cups and plates with their eyes.

Synthetic spider silk: Spider silk contains a fibrin similar to keratin in hair and horns. This protein began to become tough after it was secreted. By carefully balancing the moisture content, spiders and silkworms can prevent fibrin from curing too fast.

Electric fish and volt batteries. Through the anatomical study of the electric fish, it is found that there is a strange power generation organ in the electric fish. Italian physicist Volt designed the world's earliest voltaic battery based on electric fish power generation organs.

Jellyfish Ear: A storm predictor for jellyfish ears, which accurately simulates the organs that jellyfish feel infrasound.

animal bionics

Biologists have made high-grade silk threads, tear-resistant parachutes and high-strength cables for temporary suspension bridges through the study of spider silk. Ships and submarines are modeled after fish and dolphins.

Rattlesnake missiles are modern weapons developed by scientists imitating the "hot eye" function of snakes and their tongues are arranged with a natural infrared sensing ability like a camera.

The rocket takes off by using the recoil principle of jellyfish and squid.

Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability.

Scientists studied frog eyes and invented electronic frog eyes.

Termites not only use adhesive to build their anthills, but also spray adhesive on their enemies through small tubes in their heads. So people made a working weapon-dry rubber shell according to the same principle.

The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes.

Drawing lessons from the bionics principle and the fur structure of terrestrial animals, Chinese textile scientists have designed a small barrel warm fabric with the functions of wind resistance and moisture conduction.

According to the principle that the rattlesnake's buccal fossa can feel the temperature change of 0.00 1℃, human beings invented the tracking and chasing rattlesnake missile.

Humans also used the principle of leapfrog to design a toad rammer.

Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation.

Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. Fly and fly eye camera

The compound eye of a fly has a honeycomb structure, and one compound eye has about 3,000 small eyes. They get together with quick response and clear images. Inspired by the unique structure of compound eye, scientists have developed a "compound eye camera". You can take 1 329 photos at a time. This kind of camera is mainly used to copy a large number of fine circuits of electronic computers.

Butterfly and satellite temperature control system

When the artificial earth satellite is strongly irradiated by the sun, its temperature will reach 220 degrees Celsius, while in places where there is no sun irradiation, the temperature of the satellite may drop to about MINUS 220 degrees Celsius. Without a good temperature control system, all kinds of precision instruments on the satellite will be damaged.

Later, people were inspired by butterflies and successfully solved this problem. It turns out that the butterfly has a layer of tiny scales on its body surface. Whenever the temperature rises, the butterfly is exposed to direct sunlight, and the scales will automatically open, reducing the body's absorption of sunlight heat; When the outside temperature drops, the scales will automatically close and stick to the body surface of the butterfly to control the body temperature within the normal range. Therefore, scientists have also scaled up the temperature control system of the satellite.

Squid and sidewall hovercraft

Squid is called a sea rocket. Although its body structure is simple, it can spray water at high speed in the sea, making its maximum speed reach 150 km per hour. People imitated it to make a sidewall hovercraft, which is equipped with a water jet propeller and can sail quickly on the water with a depth of less than 1 m.

Sea horseshoe crab and TV camera

Sea horseshoe crab is an arthropod that lives in the sea. It has two eyes on its back shell and 1 000 compound eyes on both sides. When it finds the shadow of the fish, it can increase the clarity of the target by highlighting the eye boundary, so as to get the outline of the fish. Isn't that how our TV cameras work?

Rattlesnakes and rattlesnakes

The rattlesnake missile is developed to simulate the thermal sensation function of the buccal fossa of the rattlesnake head. There is a buccal fossa between the eyes and nostrils of a rattlesnake, and there is an extremely thin film inside, which is a sensitive "thermal receptor" of a rattlesnake. As long as the temperature of the surrounding environment changes slightly, it will make a judgment immediately. Scientists simulated this system of rattlesnake and made an infrared thermal sensor. After the missile uses this sensor, it can track a target directionally and flexibly until it is annihilated.

Sharks and rough planes

It is generally believed that smooth aircraft fuselage can reduce the air resistance in flight, so no matter what type of aircraft, the surface is extremely smooth. However, German aircraft designers got new inspiration from sharks.

The shark's skin is very rough, but it swims very fast. After research, scientists found that sharks are covered with shallow grooves, which can make the sea slide smoothly without any vortex affecting the speed of sharks. According to this principle, Germany will design the world's first "rough plane" with a fuselage and wings similar to shark skin. It is said that it can help the plane save 8% fuel.

Small Beetles and Binary Chemical Weapons

A small beetle grows in Colombia, and its weapon is a poisonous "cannonball". Scientists dissected the little beetle and found that there were three small "rooms" in its stomach, one containing dihydric phenol aqueous solution and the other containing hydrogen peroxide. When these two liquids flow along the small tube to the third small "room", they will react chemically under the action of enzymes. So once the beetle is attacked, it will instantly release venom with a temperature as high as 100 degrees Celsius.

Inspired by this, military experts developed a binary chemical weapon. This highly toxic chemical weapon is to put two or more chemicals that can produce toxic agents in two independent containers. After 8~ 10 seconds, the diaphragm inside the container broke, and the two drugs reacted quickly, producing deadly venom at the moment of reaching the destination to kill the enemy.

Skunks and electronic fighters

As we all know, skunks will give off an unusually unpleasant smell when they are hurt by the enemy, and they will take the opportunity to escape. American scientists imitated the skunk's escape ability and developed an electronic fighter specially used for air defense radar waves.

It is equipped with a highly sensitive electronic reconnaissance receiver, which can quickly and reliably detect radar waves and judge their dangerous degree. Once it is found that artillery fire is aimed at radar waves or air defense guidance radar waves, it will issue a danger warning to the pilot, display the radar position on the screen, and put metal bars reflecting radio waves on the screen of the ground radar station, so that the enemy can't judge the real target, and then get away successfully. This topic is much more. For example, ultrasound exists in bats; Dragonfly-airplane; Clairaudient-telephone; Frog Fast Scanning System Fly Smell Detector Mantis Sickle Oviposition Scientists studied the flight secrets of bats (biān) and bats (fú), got inspiration from them and invented radar. It can be said that bats are human teachers. In fact, nature can act as a "teacher" for human beings, and there are more than one kind of bats. Humans have wanted to fly into the blue sky like birds since ancient times. Scientists carefully studied the principle of bird flight and finally invented the plane in 1903. Thirty years later, due to the continuous improvement of radio speed, the wing (Y √) often breaks due to violent shaking, which leads to the tragic disaster of plane crash and death (C √ m √ n). It took a long time for mankind to find a way to prevent such accidents. In fact, dragonflies have already solved this problem. It turns out that at the end of each dragonfly's wing, there is a thick point slightly heavier than the surrounding, which is the key to prevent the wings from shaking. If I knew this, scientists could spend less energy! Now, aircraft designers have learned this lesson and paid attention to studying the flight methods of flies, mosquitoes, bees and so on. And built many new planes with various excellent performances. Once upon a time, ships sailing in the sea never sailed fast, although their heads were sharp. Round-headed whales often easily overtake seagoing ships. What is the reason? Scientists have carefully studied the whale and found that its shape is an ideal "streamlined body", and the "streamlined body" has the least resistance in water. Later, engineers imitated the shape of whales, improved the design of the hull and greatly increased the speed of the ship at the stern. A man holds an egg and squeezes it hard, but no matter how hard he tries, it won't break. How can a thin eggshell be so strong? Scientists studied this problem with great interest, and finally found that the thin eggshell can bear such great pressure because it can evenly distribute the pressure to all parts of the eggshell. According to the characteristics of this "thin shell structure", architects have designed many buildings that are both light and material-saving. The roofs of the Great Hall of the People, Beijing Railway Station and many other famous buildings are of this "thin shell structure".
