What did people invent based on animals?

Today, my nephew asked me two questions: On what basis was the airplane invented? What did humans invent based on dandelions? I was really confused at the time, but after thinking about it, I told him: Mockingbird invented the airplane, and the parachute was invented based on the dandelion! ! I found some from the Internet and share them with you:

1. A very peculiar small gas analyzer has been copied from a nasty fly. It has been installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin.

2. From fireflies to artificial luminescence;

3. Electric fish and volt batteries;

4. The jellyfish's downwind ears are modeled after the structure and function of the jellyfish's ears. The jellyfish ear storm predictor is designed to predict storms 15 hours in advance, which is of great significance to the safety of navigation and fisheries.

5. Based on the visual principle of frog eyes, people have successfully developed an electronic frog eye. This electronic frog eye can accurately identify objects of specific shapes just like real frog eyes. After installing electronic frog eyes into the radar system, the radar's anti-interference ability is greatly improved. This radar system can quickly and accurately identify aircraft, ships, missiles, etc. of specific shapes. In particular, it can distinguish between real and fake missiles to prevent fakes from being confused with real ones.

Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the takeoff and landing of aircraft, and if it detects that the aircraft is about to collide, it can issue an alarm in time. In traffic arteries, it can direct the movement of vehicles and prevent vehicle collisions.

6. Based on the principle of bat ultrasonic locator, people also imitated the "pathfinder" for blind people. This kind of pathfinder is equipped with an ultrasonic transmitter, which can be used by blind people to find electric poles, steps, people on bridges, etc. Nowadays, "ultrasound glasses" with similar functions have been made.

7. By simulating the incomplete photosynthesizer of cyanobacteria, a biomimetic photolysis water device will be designed to obtain a large amount of hydrogen.

8. Based on research on the human skeletal muscle system and bioelectrical control, a human enhancement device - a walking machine - has been imitated.

9. The hooks of modern cranes originated from the paws of many animals.

10. The roof corrugations imitate animal scales.

11. The oars imitate the fins of a fish.

12. The saw is learned from the mantis arm, or sawgrass.

13. The Xanthium plant inspired Velcro.

14. Lobsters with a sensitive sense of smell provide ideas for people to build odor detectors.

15. Gecko toes offer encouraging prospects for making sticky tape that can be used over and over again.

16. Bay uses its proteins to create a colloid that is so strong that such a colloid could be used in everything from surgical sutures to boat repairs.

17. Squid and torpedo bait The bladder in the squid's body can secrete black liquid. When it encounters danger, it will release this black liquid to trick attackers into taking the bait. Submarine designers copied this feature of the squid and designed torpedo decoys. The torpedo lure is like a pocket submarine. It can sail according to the original course of the submarine without changing the speed. It can also simulate noise, spiral beat, acoustic signal and Doppler tone changes, etc. It is this vivid performance that makes it difficult to distinguish the authenticity of an enemy submarine or an attacking torpedo, and ultimately allows the submarine to escape.

18. Spiders and Armor Biologists have found that the strength of spider silk is equivalent to five times that of steel wire of the same volume. Inspired by this, a technology company in Cambridge, UK, trial-produced high-strength fibers like spider silk. Composite materials made from this fiber can be used to make structural materials such as body armor, bulletproof vehicles, tanks and armored vehicles.

19. Giraffes and "anti-giraffe suits" The giraffe is currently the tallest animal in the world. The distance between its brain and heart is about 3 meters. It relies entirely on blood pressure as high as 160~260 mmHg to send blood. to the brain. According to general analysis, when a giraffe lowers its head to drink water, the brain is lower than the heart, and a large amount of blood will flow into the brain, causing the blood pressure to increase even more. Then the giraffe will die from diseases such as cerebral congestion or blood vessel rupture while drinking water. However, the thick skin wrapped around the giraffe tightly hugs the blood vessels and limits blood pressure. Aircraft designers and aviation biologists designed a novel "anti-gravity suit" based on the principles of giraffe skin, thus solving the problem. The pilot of a super-fast fighter jet suffers from cerebral ischemia when suddenly accelerating into a climb. There is a device in this "anti-gravity suit" that can compress the air when the aircraft accelerates, and can also produce corresponding pressure on blood vessels, which is more powerful than the thick skin of a giraffe.

20. The "whaleback effect" of whales and submarines. Contemporary nuclear submarines can submerge under the ice for a long time, but if they launch missiles under the ice, they must break through the ice and float up, which encounters mechanical problems. problem. Diving experts were inspired by the fact that whales must break through the ice to breathe every 10 minutes. In terms of the protruding command platform enclosure and superstructure at the top of the submarine, they strengthened the material strength and made the shape imitate the back of a whale. Sure enough, they achieved "the best performance" when breaking ice. The whaleback effect.”

21. Butterfly and Satellite Temperature Control System When artificial satellites traveling in space are subject to strong sunlight radiation, the temperature of the satellite will be as high as 200 degrees Celsius; in the shadow area, the temperature of the satellite will drop to about minus 200 degrees Celsius. This can easily bake or freeze the precision instruments on the satellite, which once caused a lot of headaches for aerospace scientists. Later, people were inspired by butterflies. It turns out that a layer of tiny scales grows on the surface of the butterfly's body, and these scales regulate body temperature. Whenever the temperature rises and the sun shines directly, the scales automatically open to reduce the radiation angle of the sun, thereby reducing the absorption of sunlight heat energy; when the outside temperature drops, the scales automatically close and stick to the body surface, allowing direct sunlight to reach the scales. Keep body temperature within normal range. After research, scientists have designed a temperature control system for artificial earth satellites that is like butterfly scales.

And these:

Biologists have created a temperature control system through the study of spider silk. High-grade silk thread, tear-resistant and high-strength cable for parachutes and temporary suspension bridges. Boats and submarines come from imitations of fish and dolphins.

Sidewinder missiles and other modern weapons developed by scientists imitate the snake's "hot eye" function and the natural infrared sensing ability of a camera-like device arranged on its tongue.

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

Scientific researchers have developed a lot of military camouflage equipment for the troops by studying the color-changing ability of chameleons.

Scientists studied frog eyes and invented electronic frog eyes.

Termites not only use adhesive to build their mounds, but they can also spray adhesive at their enemies through small tubes on their heads. So people made a working weapon based on the same principle - a piece of dry glue cannonball.

The U.S. Air Force has developed a miniature thermal sensor through the "heat eye" function of the Viper.

Chinese textile technicians used the principles of bionics and the fur structure of land animals to design a KEG thermal insulation fabric that has windproof and moisture-conducting functions.

Based on the principle that the cheek pit of a rattlesnake can feel a temperature change of 0.001°C, humans invented the tracking and pursuit rattlesnake missile. Humans also designed a toad ram using the principle of leaping frog. Humans imitate the highly sensitive sense of smell of police dogs to create "electronic police dogs" for detection. Scientists made the world's first gas masks based on the wild boar's nose's unique ability to detect poison.

1. Spherical Palace: A round nest cleverly woven by the African munia with its beak and feet. It starts from a round bracket, forms a ball, and finally hangs it on a branch.

2. Stable lightweight structure: The cardboard box-shaped nest built by field bees is very delicate. Although it is a lightweight structure, it is incredibly stable.

3. Perfect gluing: The nest of web-weaver ants is made of leaves glued together. Their larvae spit out adhesive and are ideal "glue bottles".

4. Round tower house in the tree: The house of the round tower bird looks like a crumbling firewood pile on the tree, but its structure is very strong and can last for decades, often to The tree was overwhelmed and crushed.

5. "Stove" stove on a tree branch: The bird's nest is made of clay and is usually placed on a relatively stable tree branch. A nest requires about 2,500 grains of clay, which are all brought in by the ovenbird's beak.

6. Platform building complex: Tropical stingless bees use beeswax to build honeycombs. The layers are stacked together. There are usually 40 layers. The appearance looks like the spaceship in the movie "Star Wars". It can accommodate 100,000 "residents".

7. Air-conditioned castle: Termites can improve the temperature inside the nest through an incredible pipe system, cooling it during the day and heating it at night.

Jellyfish is almost entirely made of water. The water in its body actually accounts for 98%. There is a large amount of liquid between the molecules that make up its body, and it can be obtained from it after refining. Commonly used polymer glues

Lu Ban, a famous craftsman in ancient my country, cut his hand on a silk spear grass when he went up the mountain to cut down trees. He felt strange, how could a small piece of grass be so powerful? After careful observation, he found that the edges of the silk grass leaves had many sharp teeth. So Lu Ban invented the saw for woodworking.

The fly does not have a "nose", so how does it rely on its sense of smell? It turns out that the fly's "nose" - olfactory receptors are distributed on a pair of antennae on the head. A very unique small gas analyzer was successfully copied. This instrument has been installed in the cockpit of the spacecraft to detect the composition of the gas inside the cabin. It can also measure harmful gases in submarines and mines. Using this principle, it can also be used to improve the input device of the computer and the structural principles of the gas chromatography analyzer.

As early as the 1940s, people created fluorescent lamps based on research on fireflies. In recent years, scientists first isolated pure luciferin from the light emitters of fireflies, and later isolated luciferase. , and used chemical methods to artificially synthesize fluorescein. A biological light source mixed with luciferin, luciferase, ATP (adenosine triphosphate) and water can be used as a flashlight in mines filled with explosive gas. Since this kind of light has no power source and does not generate a magnetic field, it can be used to clear magnetic mines under the illumination of biological light sources.

In the early 19th century, the Italian physicist Volta designed the world's earliest voltaic battery using the electric fish's power-generating organ as a model. Because this battery is designed based on the natural generator of electric fish, it is called an "artificial electric organ."

Architecturally, the long-span thin-shell building imitating the shell and the columns imitating the femur structure not only eliminate areas where stress is particularly concentrated, but also use the least building materials to bear the maximum load.
