What are the examples of bionics?

1. Fireflies and fluorescent lamps. As early as the 194s, scientists were inspired by fireflies and invented fluorescent lamps, which greatly improved the energy utilization rate, but it was far from the luminous rate of fireflies. The field of bioluminescence is a hot research topic in foreign countries in the past two years. In 28, the Nobel Prize in Chemistry was awarded to three scientists in the field of bioluminescence.

2. Frog eyes and electronic frog eyes. According to the principle and structure of frog eye, bionic scientist Locke invented electronic frog eye. In modern warfare, the enemy may launch missiles to attack our targets. At this time, we can launch anti-missiles to intercept each other's missiles, but in order to confuse us, the enemy may also send signals to disturb our sight.

3. A fisheye lens is a lens with a focal length of 16mm or less and a viewing angle close to or equal to 18.

is an extreme wide-angle lens with the highest viewing angle among many lenses. In order to make the lens reach the maximum photographic angle, the front lens of this kind of photographic lens has a short diameter and protrudes to the front of the lens in a parabolic shape, which is quite similar to the fish's eyes, hence the name "fisheye lens".

4. Dog's nose and electronic police dog. What's so special about a dog's nose? It turns out that the noses of all kinds of animals are basically the same in structure. There are many folds in the upper part of the nasal cavity, and there is a layer of mucosa on the folds. There are many olfactory cells hidden in the mucosa. When the "smell" molecules dissolve in the mucus in the mucosa, it will stimulate the olfactory cells to send signals to the olfactory center of the brain immediately, so animals have the feeling of "smell".

5. Dolphins help people improve submarines. According to the principle of dolphin skin structure, organic materials are used to imitate "dolphin skin", and it is applied to submarines. Putting this imitation "dolphin skin" on the submarine shell not only reduces half of the resistance during sailing, but also increases the sailing speed by more than one time.
