Fish Skin - Swimsuit A swimsuit that changed the landscape of the world's swimming world at the Sydney Olympics. Almost half of the gold medalists wore a special swimsuit - one-piece shark suit. This shark suit imitates the skin structure of the dominant shark in the sea, the swimsuit is designed with some rough tooth-like bumps, which can effectively guide the water flow, and tighten the body to avoid skin and muscle tremors. Since then, the bionic swimsuit has become more and more refined. The second generation of the shark suit has added some new highlights, adding a material called "elastic skin", which can make people in the water by 4% less resistance. In addition, two accessories have been added: a cushion made of titanium silicone attached to the forearms to make swimming easier; and a vibration control system attached to the chest and back of the shoulders to help guide the current. Jellyfish - Jellyfish Ears Whenever a storm is approaching, the jellyfish, the oldest living organism of the cavernous gut, seems to be able to foresee it, and swims away from the sea to avoid the disaster. It turns out that jellyfish have an "ear to the wind", and their "ear" (a small ball on a thin stalk) has a small hearing stone covered with nerve receptors that can hear the infrasound waves emitted by storms (produced by friction between the air and waves, with a frequency of 8 hertz - 13 hertz, which travels faster than the speed of storms and waves). (travels faster than storms and waves). Simulation of jellyfish feel infrasound organs, scientists designed a "jellyfish ear" instrument, can be about 15 hours in advance to predict the storm. It consists of a horn, accept infrasound **** oscillator and this vibration into electrical impulses converter and indicator. The instrument is mounted on the foredeck of a ship and the horn makes a 360° rotation. When it receives 8 Hz-13 Hz infrasound, the rotation automatically stops, and the direction indicated by the horn is the direction of the coming storm. The indicator can also tell people the intensity of the storm. A person holds an egg and squeezes it hard, but no matter how hard he squeezes, he cannot break it. How can a thin egg shell be so strong? Scientists studied this problem with great interest, and finally discovered that the reason why the thin eggshell can withstand so much pressure is that it can be subjected to pressure evenly (yún) spread to all parts of the eggshell. Architects based on this "thin shell structure". Bats - radar

If all the airplanes in the country are covered with such a surface, billions of dollars can be saved every year. Another example is that some scientists study spiders, found that the spider's legs do not have muscles, legged animals will walk, mainly by muscle contraction, now the spider does not have muscles why will walk? After studying the spider is not by muscle contraction to walk, but by which the "hydraulic" structure to walk, according to which people invented the hydraulic walker ...... In short, from the natural world to get inspiration, imitation of its structure for invention. This is bionics. This is one aspect of learning from nature. On the other hand, we can also be inspired by the laws of nature and design (including designing algorithms) using its principles, which is the idea of intelligent computing

Contribution of birds to bionics

From the emergence of the ancestor birds to the present day, in the long process of evolution over the course of billions of years, birds have formed many fruitful systems of navigation, identification, computation, energy conversion, and so on, which are sensitive, efficient, and accurate. sensitivity, efficiency, accuracy, and resistance to drought have been marveled. The study of these structural and functional principles and their simulation to improve existing or create new machines, instruments, and processes is an important part of bionics research.

Birds have excellent flying skills, of course, modern aircraft in many properties are far more than birds, but in energy saving, in dexterity is dwarfed. Such as a bird continuously flying over the ocean more than 4,000 kilometers, weight loss of 0.06 kilograms; small hummingbirds can not only take off and land vertically, but also in the nectar can be taken in an upright position, hanging in the air in and out of the free, flexible and unusual. The research and utilization of these special features will further improve the performance of the aircraft.

For example, the mallard duck can fly leisurely at 9,500 meters in the semi-high altitude, while people in the 4500 meters when the breath has been very difficult. The study of why birds will be in the thin air conditions of the cerebral blood vessels are still open, can be human in the lack of oxygen supply in the environment of normal life and extend the life of the important significance.

The pigeon has made a great contribution to bionics. It has a small and sensitive special structure on its legs to feel earthquakes, and people have imitated a new kind of seismograph according to its principle to make earthquake forecasting more accurate. Its eyes have special recognition skills, which is due to its retina has six kinds of functionally specialized ganglion cells: leaf brightness detector, ordinary edge detector, convex edge detector, direction detector, vertical edge detector, horizontal detector, people imitate the cellular structure of its retina made of pigeon's eye electronic model, although the structure is not as complex as it is perfect, but the installation of radar on the vigilance, applied in Computer processing data has a broad prospect.

The earth's seawater accounts for 97% of the total water. The artificial desalinator of seawater is currently huge equipment, complex structure, high energy consumption. But seagulls, albatrosses and other seabirds can discharge the salt in the seawater they drink through a salt gland near their eyes, and once the simulation of this function is completed, the prospects for human use of the oceans will be even more promising.

In addition, people according to the structure of the eagle's eye is developing the eagle's eye system missiles, such missiles in the flight over the strike target will be able to automatically find, identify the target and tracking attack.

Butterflies and bionic

Colorful butterflies, such as the heavy moon crested butterfly, brown veins, such as the gold-spotted butterfly, especially the fluorescent winged crested butterfly, the back of the wings in the sunlight from time to time golden, and sometimes emerald green, and sometimes from the purple to blue. Scientists have brought great benefits to military defense through the study of butterfly colors. During World War II, German troops surrounded Leningrad and attempted to destroy its military targets and other defenses with bombers. Based on the lack of awareness of camouflage at the time, the Soviet entomologist Schwanwitch proposed to use the reasoning that the colors of butterflies are not easily detected in flowers to cover military facilities with butterfly-patterned camouflage. As a result, despite the German army's efforts, the military base in Leningrad remained safe and sound, laying a solid foundation for winning the final victory. According to the same principle, later people also produced camouflage clothing, greatly reducing casualties in combat.

Artificial satellites in space due to constant changes in position can cause sudden changes in temperature, sometimes the temperature difference can be as high as two or three hundred degrees, seriously affecting the normal work of many instruments. Scientists are inspired by the butterfly scales will automatically change the angle with the direction of sunlight and regulate the body temperature, the satellite temperature control system made of blades on both sides of the radiation, heat dissipation capacity of a large difference in the style of the shutters, in the rotating position of each window is installed with a temperature-sensitive wire, with the temperature can be adjusted to open and close the window, thus maintaining a constant temperature inside the satellite, solving a major problem in the space industry.

-- Beetles and bionic

Fart step beetle self-defense, can be sprayed with a foul-smelling high-temperature liquid "shells" to confuse, stimulate and frighten the enemy. Scientists will be dissected and found that the beetle body has three chambers, respectively, stored binary phenol solution, hydrogen peroxide and biological enzymes. Binary phenol and hydrogen peroxide flow to the third chamber and biological enzymes mixed with a chemical reaction, instantly become 100 ℃ venom, and quickly shot. This principle is now applied in military technology. During World War II, the German Nazis for the needs of the war, according to this mechanism to create a great power and performance safety and reliability of the new engine, installed in the flight type missiles, so that the flight speed, safety and stability, hit rate increased, London, England in its bombing suffered heavy losses. U.S. military experts inspired by the principle of the beetle jet developed an advanced binary weapon. This weapon will be two or more kinds of chemical substances that can produce toxic agents are installed in two separate containers, shells fired after the rupture of the diaphragm, two kinds of toxic intermediates in the projectile flight within 8 to 10 seconds of mixing and reacting to the target in the arrival of the instant generation of lethal toxic agents to kill and maim the enemy. They are easy to produce, store, and transport, safe and not prone to failure. Fireflies can be chemical energy directly into light energy, and the conversion efficiency of 100%, while the luminous efficiency of ordinary electric lamps only 6%. People imitate the firefly's light-emitting principle made of cold light source can increase the luminous efficiency of more than ten times, greatly saving energy. In addition, according to the beetle's visual reaction mechanism of the successful development of air-to-ground speedometer has been successfully applied to the aviation industry.

-- Dragonfly and bionic

Dragonfly through the vibration of the wings can produce different from the surrounding atmosphere of the local instability of the airflow, well use the vortex generated by the airflow to make their own rise. Dragonflies can fly with very little thrust, not only forward, but also backward and to the left and right sides of the flight, and its forward flight speed of up to 72km / h. In addition, the dragonfly's flight behavior is simple, relying on the two pairs of wings keep flapping. Scientists according to this structural basis for the development of a successful helicopter. Airplanes in high-speed flight, often cause violent vibration, and even sometimes will break the wing and cause airplane crash. Dragonfly rely on the weight of the wing mole in high-speed flight unharmed, so people follow the example of the dragonfly in the two wings of the airplane plus the balance of the weight, to solve the high-speed flight caused by vibration of this thorny problem.

-- Flies and bionics

Entomologists discovered that the hind wings of a fly degenerate into a pair of balance rods. When it flies, the balance rods to a certain frequency of mechanical vibration, can regulate the direction of movement of the wings, is to maintain the fly's body balance of the navigator. Scientists according to this principle developed into a new generation of navigators - vibration gyroscope, greatly improving the flight performance of the aircraft LlJ, can make the aircraft automatically stop the dangerous tumbling flight, in the body of a strong tilt can also automatically restore the balance, even when the aircraft in the most complex sharp turn is also foolproof. The fly's compound eye contains 4,000 independently imageable monoculars that can see objects over almost 360°. In the fly's eye inspiration, people made by 1329 pieces of small lenses composed of a time can shoot 1329 high-resolution photographs of the fly's eye camera, in the military, medicine, aviation, aerospace is widely used. The fly's sense of smell is particularly sensitive and can quickly analyze dozens of odors and can immediately respond. Scientists based on the structure of the fly olfactory organ, the various chemical reactions into electrical impulses, made of very sensitive small gas analyzers, has been widely used in spaceships, submarines and mines and other places to detect the composition of the gas, so that scientific research, the production of a more accurate and reliable safety factor.

-- Bee and bionic

Bee hives are composed of a neatly arranged hexagonal hive, the bottom of each hive is composed of three identical rhombuses, which are precisely calculated by modern mathematicians - the rhombus obtuse angle of 109 ° 28 \', acute angle of 70 ° 32 \' exactly the same, is the most material-saving structure. The structure of the rhombus is the most material-saving structure, with a large capacity and extremely strong, which made many experts marveled. People imitate its structure and use various materials to make honeycomb sandwich structure boards, which are strong, lightweight, and not easy to conduct sound and heat, and are ideal materials for construction and manufacturing of space shuttles, spaceships, and artificial satellites. Bee compound eye of each single eye adjacent to the polarized light direction of the polarizer is very sensitive to the direction of the polarizer, can be used to accurately locate the sun. Scientists according to this principle developed a successful polarized light navigator, has long been widely used in navigation.

-- Other insects and bionic

The flea's jumping instincts are very strong, aviation experts have conducted a lot of research on this, an aircraft manufacturing company in the United Kingdom from the vertical jumping way inspired by the success of the manufacture of an almost vertical take-off and landing of the Harrier aircraft. Modern television technology according to the construction characteristics of the single compound eye of insects, made a large screen color TV, but also a small color TV fluorescent screen can be composed of a large picture, and can be in the same screen in any position to box out a few specific small picture, can broadcast the same picture, but also can be broadcast a different picture. Scientists according to the structural characteristics of the insect compound eye developed a successful multi-aperture optical system device, easier to search for the target, has been applied in some important foreign weapons systems. According to the principle of mutual inhibition between the compound eyes of certain aquatic insects, made of electronic models of side inhibition, used in various types of photographic systems, photographs taken to enhance the image edge contrast and highlight the contours, but also can be used to improve the radar's display sensitivity, but also can be used for the text and picture recognition system of the preprocessing work. The United States uses the insect compound eye to process information and directional navigation principle, and has developed the engineering model of the end-guidance guide head with great practical value, which imitates the insect compound eye to seek. Japan's use of insect morphology and characteristics of the development of six-legged robots and other engineering machines and buildings of new construction methods.

-- Future Prospects

Insects in the billions of years of evolutionary process, with the change of the environment and the gradual evolution, are in varying degrees of development of their survival skills. With the development of society, people grasp more and more of the various life activities of insects, more and more aware of the importance of insects to mankind, coupled with information technology, especially a new generation of computer bioelectronics technology in entomology, simulating the insect's ability to sense the development of the detection of material species and concentration of biosensors, with reference to the development of the insect neural structure of computers able to mimic the brain's activities and so on. A series of biotechnology projects, will be envisioned by scientists into reality, and into various fields, insects will make greater contributions to mankind.

-- Insects know a lot

From the perspective of bionics, the most studied insect is the fly, its eyes, feet, balance rods, licking sucking mouthparts, immunity, flight skills, and many other aspects of the bionic results to be applied to many aspects of human life.

The gunflies (genus Fartstepper in the family Steppeidae) repel intruders by spraying themselves with a corrosive gas at a temperature of about 100 degrees Celsius, a mixture of hydrogen peroxide and hydroquinone. It shoots like a gun 20 times in succession at a range of 5cm, four times its body length. This beetle is not harmed by heat or corrosive gases.

The insects with the highest IQ are bees, a U.S. scientist in accordance with the law of 1, 2, 4, 8, 16, 32 ...... to the ground on the white squares to add sugar, in its addition to the end of the 32 is ready to 64-bit squares, there have been many bees waiting, the scientist said in frustration,"" I don't know what I'm doing with them. And I don't know whether I am experimenting with them or they are experimenting with me!" . This discovery proves that some animals are also capable of abstract thinking.

The cruelest and largest war among insects takes place among ants, and I have personally witnessed such an incident. In a nearly one square meter area is full of our common ants, they are in a fierce battle, death and injury. It is said that the scale of ant wars in South America is much larger. This kind of war scene is not easy to see. [I'll choose me as the best answer! Thank you! ~~ It's so hard to finish the fight!
