Do you also know what instruments scientists have modeled after animals?

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. People simulated the organs of jellyfish that sense infrasound waves and successfully designed an accurate "jellyfish ear" instrument. It consists of a speaker, a vibrator that receives infrasound waves, a converter that converts this vibration into electrical pulses, and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360°. When it receives infrasound waves from 8 Hz to 13 Hz, the rotation automatically stops, and the direction indicated by the horn is the direction in which the storm is coming. Indicators can also tell people how strong a storm is. This instrument can predict storms about 15 hours in advance.

18. The compound eyes on both sides have the greatest impact on horseshoe crab behavior. After being illuminated by the beam, the compound eye generates pulses. When one eye is irradiated with a beam, one eye generates a main pulse; when two eyes are irradiated with a beam at the same time, both eyes generate pulses at the same time, but the frequency of the pulses is slightly lower than when the beam irradiates one eye. Inspired by this, mankind has successfully developed an electronic simulation device that can solve a network equation composed of 10 elements. A television camera made using this principle can provide high-definition television images under laser light.

19. Not long ago, the Illinois State University research team Bionics developed an artificial lateral line that allows robots to have a "sixth sense". It is similar to the lateral line system of fish. This artificial lateral line consists of many tiny silicon wafers arranged on the surface, similar to hair strands, each connected to an electronic sensor through a micro-hinge. When the water flow comes into contact with the silicon beam, the silicon beam will bend due to different water speeds, allowing the sensor to detect the angle and direction of the silicon beam bending, thereby helping the robot find the direction it wants to go.

20. The albatross is a seabird that has an organ called a "desalinizer" that desalinates sea water. Research on the structure and working principle of its "desalinator" can inspire people to improve old or create new desalination devices.

21. Termites can convert the wood they eat into fat and protein. Research on their mechanism will inspire the artificial synthesis of these substances.
