The ancients saw fish swimming freely in the water, how envious they were of their skills! Later, after imitating the body shape of fish, it was made into a hull, and after imitating the pectoral fin and caudal fin of fish, it was made into a double paddle and a single paddle. From then on, humans can move freely on the water. According to the flight principle of birds, a plane was made to fly in the blue sky, realizing the dream of flying in the sky.
By studying the dog's nose, human beings imitated and made a small, fast and sensitive automatic analyzer-"electronic nose", which can be used in chemistry and food industry, and can also be used to analyze the gas composition in mines, warehouses, submarines and spacecraft cabins, and can also be used for prospecting and leak detection of gas pipelines. Now, the electronic police dog has been successfully developed, which can be used to detect toxic gases, dyes, paints, acids, ammonia, benzene, gas and the smell of fresh apples and bananas, and the concentration of gas can be measured to one in ten thousand. Its sensitivity has reached the level of dog nose, and it can also be used for detective work.
By studying the gill of fish respiratory organs, human beings imitate the structure of fish gill, and make a translucent membrane with gill function with two layers of silicone rubber membrane, which can be used as an "artificial gill" for people to breathe in water. Humans have also made an efficient "seawater desalination device" based on the mechanism of crocodile discharging salt, which can be used to extract or concentrate some dispersed elements. ...
The eyes of flies are composed of 6000 to 8000 small eyes, which are called compound eyes. Humans made a "compound eye camera" by imitating the eyes of flies. This kind of camera can take 1329 different photos at a time when it is installed on a satellite, and can be used to copy the particularly fine micro-circuits of electronic computers. If this camera is used for stamp printing, one board can print 25 stamps, and one photo can be taken at a time. Take 25 pictures one by one with an ordinary camera.
Humans have studied the eggshells of oviparous animals, which are thin and strong and have strong pressure resistance. Imitating the shape characteristics of egg shell, a kind of "thin shell structure" is created, which is both material-saving and compression-resistant, and is widely used in construction engineering.
By studying bioluminescence such as fireflies, human beings are further creating new efficient artificial cold light sources. How wonderful it would be if we could create a substance that glows like a living thing and paint it on the indoor wall, so that it can receive light and store energy during the day and then glow naturally at night!
It can be seen that studying the characteristics of animals is helpful to broaden our horizons, emancipate our minds, boldly imagine and practice, so as to design blueprints of various construction machinery and create more exquisite and perfect modern technical devices.
