Please give some examples of animal bionics! !

Scientists have invented an artificial cold light, and the light passing through fireflies will not hurt the eyes. Because this kind of light has no power supply, it will not produce magnetic field, and it can be used to clear magnetic mines under the irradiation of biological light source.

2, jellyfish ear storm forecaster

Before the warning of storm at sea, the friction between waves and air produced infrasound of 8~ 13HZ, which could not be heard by human ears, but could be heard by jellyfish's special auditory system. Scientists invented the jellyfish ear storm predictor by studying and imitating the auditory system of jellyfish.

3. Pathfinder

According to the principle of bat ultrasonic locator, people also copied "Pathfinder" for the blind. This pathfinder is equipped with an ultrasonic transmitter, which blind people can use to find telephone poles, steps, people on bridges, etc. Nowadays, "ultrasonic glasses" with similar functions have also been made.

4. Butterfly and satellite temperature control system

When the artificial earth satellite is exposed to strong sunlight in space, all kinds of precision instruments on the satellite are easily "baked" or "frozen". A thin layer of scales will grow on the body surface of butterflies to regulate their body temperature. Scientists simulated the structure of butterfly wings, and designed and loaded a temperature control system similar to butterfly scales for the sun surface of artificial satellites.

5. giraffes and astronauts

The reason why giraffes can send blood to their heads through their long necks is that giraffes have high blood pressure. According to the measurement, giraffe's blood pressure is twice as high as human normal blood pressure. Why can't such a high blood pressure cause giraffe to die of cerebral hemorrhage? This is related to the giraffe's body structure. Giraffe's muscles around blood vessels are very developed, which can compress blood vessels and control blood flow.

Inspired by this, scientists are training astronauts to set up special equipment so that astronauts can use this equipment to exercise every day to prevent muscle degeneration around blood vessels. When the spacecraft was launched, scientists developed a flight suit "anti-load suit" based on the principle that giraffes can control vascular pressure with tight skin. The anti-load suit has an inflatable device, and with the increase of the speed of the spacecraft, the anti-load suit can be inflated with a certain amount of gas.
