The Story of Biomimicry 15, What are some examples of bionics?

1. Bats and radar.

Bats emit a kind of ultrasound wave that comes back when it encounters an object, but humans can't hear it. Radar was invented based on this property of bats. Radar is used in a variety of places, such as airplanes, aviation, etc.

2. Artificial cold light.

In nature, there are many organisms that can emit light, such as bacteria, fungi, worms, mollusks, crustaceans, insects and fish, etc., and the light emitted by these animals does not produce heat, so it is also called "cold light". Among the many light-emitting animals, fireflies are one of them.

There are about 1,500 species of fireflies, and the colors of their cold light range from yellow-green to orange, and the brightness of the light varies. The cold light emitted by fireflies not only has a high luminous efficiency, but also the cold light emitted is generally very soft, which is very suitable for human eyes, and the intensity of the light is relatively high. Therefore, biolight is a kind of light that is ideal for human beings.

3. Volt battery.

There are many living things in nature that can generate electricity, and there are more than 500 species of fish alone. People refer to these fish, which can discharge electricity, collectively as "electric fish".

The ability of various electric fish discharges varies. The most powerful discharges are electric rays, electric catfish, and electric eels. Medium-sized electric rays can produce voltages of around 70 volts, while African electric rays can produce voltages of up to 220 volts; The African electric catfish can produce a voltage of 350 volts; Electric eels can produce up to 500 volts, and one South American electric eel can produce up to 880 volts, which is the champion of electric shocks, and it is said to be able to kill large animals like horses.

4. Zebra. Zebras live on the African continent and look no different from ordinary horses, with stripes on their bodies being a protective color that has evolved to adapt to their environment. Of all the zebras, the fine zebra is the largest and most beautiful.

It is 140-160 cm tall at the shoulders, and its ears are round and large, with fine and numerous stripes. Zebras often live with wildebeest, whirlhorned oryx, gazelles and ostriches in the grasslands to ward off predators. The use of zebra stripes in the military is a very successful example of biomimicry.

5. Insects and biomimicry.

Insects are small, large in variety and number, accounting for more than 75% of living animals, and are found all over the world. They have their own survival skills, some of which are inferior to even humans. The use of natural resources is becoming more and more extensive, and any achievement in biomimicry, in particular, comes from a certain characteristic of living things.

1。Flies, successfully imitated a very peculiar small gas analyzer. It has been installed in the cockpit of a spacecraft to detect the composition of the gases in the cabin.

2。fireflies to artificial cold light;

3。Electric fish with volt batteries;

4。The downwind ears of jellyfish, imitating the structure and function of jellyfish ears, designed the jellyfish ear storm instrument, which can predict the storm 15 hours in advance, which is of great significance to the safety of navigation and fishery.

5。The visual principle of frog eyes has successfully developed an electronic frog eye. This electronic frog eye can identify objects of a specific shape with the same accuracy as a real frog eye.

After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved. This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.

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 can issue an alarm if it detects that the aircraft is about to collide. In the traffic arteries, it can direct the driving of vehicles and prevent the occurrence of vehicle collisions.

6。The principle of the bat ultrasonic locator, people also imitate the "pathfinder" used by the blind. This pathfinder is equipped with an ultrasonic emitter that a blind person can carry to spot people on electric poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.

7。An incomplete photosynthesizer that mimics cyanobacteria will be designed to bionic photolyzed water, so that a large amount of hydrogen can be obtained.

8。The study of the muscular system and bioelectric control of the human bone has imitated the human augmenter, the walking machine.

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

10。The roof corrugated roof mimics the scale armor of animals.

11。The oars mimic the fins of a fish.

12。The saw learns the mantis arm, or sawgrass.

13。Xanthium was inspired to invent Velcro.

14。Lobsters with a keen sense of smell provide ideas for people to make odor detectors.

15。Gecko toes offer an encouraging prospect for creating adhesive tapes that can be used over and over again.

16。The colloids produced by shellfish from their proteins are so strong that they can be used for everything from surgical sutures to ship repairs.

17。A swimsuit made according to the characteristics of a shark that minimizes resistance.

18。Airplane (bird).

19。Submarine (fish).

20。Radar (bat).

21。The lotus leaf meridian structure is used in architecture (Great Hall of the People).

22。Lotus mud without staining (inspired by the fluffy structure on the surface of the lotus leaf, using nano materials to make anti-fouling and waterproof fabric).

23.。Chameleons change color in different environments, leading to the invention of color-changing glass.

Excerpts from the web).

Radar was invented based on the pathfinding of bats.
