According to the visual principle of frog's eye, people have successfully developed an electronic frog's 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.

According to the working principle of limulus compound eye side suppression network, some devices that can enhance the image contour and improve the contrast have been successfully developed, which is helpful to the detection of blurred objects. More than 100 neuron models are established, and a new computer is constructed on this basis.
Inspired by bats, radar has made great achievements in the military.
Computers like today were invented by imitating the human brain.
This car was copied from the carriage.
Researchers imitate the self-purification principle of lotus leaves, and the United States has begun to study how to apply this self-purification principle to automobile manufacturing so that drivers don't have to wash their cars every day. Shanghai has also developed nano-coatings with self-cleaning effect. In the process of drying and film forming, the concave-convex morphology similar to lotus leaf will be formed on the surface of the coating, and a hydrophobic layer will be constructed.
Shark skin-one-piece shark suit. This shark suit imitates the skin structure of the overlord shark in the sea. Some rough dentate protrusions are designed on the swimsuit, which can effectively guide the water flow, tighten the body and avoid the vibration of the skin and muscles.
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%. In addition, two accessories have been added, and the bumper made of titanium silicone attached to the forearm can make athletes swim more easily; Vibration control systems attached to the chest and shoulders can help guide the water flow.
By simulating the organs of jellyfish that feel infrasound, scientists and technicians have designed a "jellyfish ear" instrument, which can forecast storms about 15 hours in advance. 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.
For example, German tire design experts designed an AMC pad tire according to the function of cat's front paw pad and the compliant structure and stability of spider web in running. Its surface flexibility and rigid mesh structure design have great grip and running accuracy, which increases the friction between the tire and the ground, shortens the braking distance from the current 19 meters to 9 meters, and greatly improves the safety.
The surface structure of the inner barrel of a new washing machine designed by Miller Company in Germany imitates the shape of honeycomb and turtle shell. The washed clothes are clean, but the washing process is smooth and does not hurt the material.

Bees and polarization directors, bees will not get lost when collecting pollen, because they have a pair of compound eyes on their heads, each of which consists of 6300 units. After the light enters the lens of the eye, it passes through the crystal cone and reaches the photosensitive beam containing photosensitive pigment. Photosensitive pigment molecules are particularly sensitive to polarized light, so they have good directional function. Especially when dark clouds cover the sun, the time and direction can be corrected according to the change of the sun's orientation. Scientists have benefited from the ability of bees to orient polarized light and developed polarization directors for airplanes and ships.
Rattlesnake and thermal locator, the vision of rattlesnake is almost zero, but the buccal fossa organ on its nose has thermal location function, and it can feel the temperature difference of 0.00 1 degree Celsius, and the reaction time does not exceed 0. 1 second. Even after reptiles and small animals fall asleep at night, rattlesnakes can quickly perceive and hunt with the heat emitted by their bodies. Scientists have developed modern night vision devices, air-to-air rattlesnake missiles and bionic infrared detectors according to the special functions of rattlesnakes.
Pigeons and early warning radar, pigeon's retina is mainly composed of outer cone, middle bipolar cell, posterior nerve cell and optic tectum, which can make special response to brightness, edge, direction and movement, so people call pigeon's eyes "divine eyes". Scientists have developed an electronic model of pigeon's eyes by imitation, which is used in early warning radar system and improves the detection ability. Between the Noctuidae and the ultrasonic alarm, and between its chest and abdomen, there is a pair of special hearing organs called tympanic membrane, which can distinguish the ultrasonic waves emitted by bats from the strong background noise, and its thick fluff can also absorb the detection ultrasonic waves emitted by bats, thus being in a "stealth" state in front of natural enemies. Scientists use the fluff material on the moth body in aircraft, ships and other equipment, which greatly reduces the probability of the target being found by radar, infrared and ultrasonic waves.
Giraffe and anti-Dutch flight suit, giraffe's neck is very long, and the distance between brain and heart is about 3 meters. In order to transport blood to the head, the blood pressure is relatively high, about twice that of the human body. But when the giraffe bowed its head and drank water, the blood did not rush to its head. It turned out that the thick skin wrapped around the giraffe played a role. When giraffes bow their heads, thick skin tightly binds blood vessels, limiting their blood pressure, and accidents will not occur because of the sudden increase of blood pressure. According to the principle of giraffe's thick skin, the anti-load flight suit designed by pilots plays a role in limiting blood pressure to a certain extent. When the plane accelerates, the anti-load flight suit can also compress air and exert certain pressure on blood vessels, which is better than the giraffe's thick skin.
