The inspiration of nature to human beings is varied. Nature's nest is naturally muddy plain, but it is inspired by this that human beings have developed architectural science and established modern big cities. The rivers of nature seem to run day and night regardless of people's will, but aren't they also teaching people how to understand many truths such as gravity and inertial force of motion, and how to develop and utilize the potential of nature? Metal has given more inspiration to mankind. Such seemingly hard things, after being melted by fire, can be turned into human tools according to human needs. More importantly, it makes people understand that all substances have melting points and can be transformed into shapes and states.

Humans made airplanes based on sharks and radars based on bats. Humans invented airplanes based on dragonfly wings, radars based on bats' mouths and ears, ships based on whale shapes, and electronic frog eyes based on frog eyes.

A very strange small gas analyzer was successfully copied from annoying flies. It has been installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin.

From fireflies to artificial luminescence;

Electric fish and volt batteries;

The windward ear of jellyfish imitates the structure and function of jellyfish ear, and designs a storm predictor of jellyfish ear, which can predict the storm 15 hours in advance, which is of great significance to navigation and fishery safety.

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

By simulating the incomplete photosynthetic mechanism of cyanobacteria, a bionic photolysis device was designed to obtain a large amount of hydrogen.

According to the study of human skeletal muscle system and bioelectricity control, a human strength enhancer-walking machine is copied.

The hook of modern crane originated from the claws of many animals.

Corrugated roofs imitate animal scales.

Paddles imitate the fins of fish.

Saw mantis arms, or saw grass.

The plants of Xanthium were inspired to invent velcro.

Lobster with keen sense of smell provides people with the idea of making odor detectors.

Gecko toes provide an encouraging prospect for manufacturing reusable adhesive tape.

The colloid formed by shellfish and protein is very strong, and this colloid can be used in everything from surgical suture to ship repair.

According to bats, radars, fish, submarines, birds, airplanes, fireflies, fluorescent lamps,
