What are the achievements of human bionics?

1. Fireflies and fluorescent lamps. As early as the 1940s, scientists were inspired by the light emitters of fireflies and invented fluorescent lamps, which greatly improved energy efficiency, but they were still far behind the luminescence rate of fireflies. The field of bioluminescence is a scientific research hotspot that has gradually emerged abroad in the past two years. The 2008 Nobel Prize in Chemistry was awarded to three scientists in the field of bioluminescence.

2. Frog eyes and electronic frog eyes. Biomimetic scientist Locke invented the electronic frog eye based on the principle and structure of the frog eye. In modern warfare, the enemy may launch missiles to attack our targets. At this time, we can launch anti-missiles to intercept the opponent's missiles. However, in order to confuse us, the enemy may also launch signals to disrupt our line of sight.

3. Fisheye lens is a lens with a focal length of 16mm or shorter and a viewing angle close to or equal to 180°.

It is an extreme wide-angle lens with the highest viewing angle among all lenses. In order to achieve the maximum photographic angle of the lens, the front lens of this photographic lens is very short in diameter and protrudes parabolically towards the front of the lens, which is quite similar to the eye of a fish, hence the name "fisheye lens".

4. Dog’s nose and electronic police dog. What’s so special about dogs’ noses being so sensitive? It turns out that the noses of various animals have roughly the same structure. There are many folds in the upper part of the nasal cavity, and there is a layer of mucous membrane on the folds. There are many olfactory cells hidden in the mucous membrane. When the "smell" molecules dissolve, In the mucus in the mucous membrane, the olfactory cells are stimulated to immediately send signals to the olfactory center of the brain, so the animal has a sense of "smell".

5. Dolphins help people improve submarines. Based on the principle of dolphin skin structure, organic materials are used to imitate "dolphin skin" and applied to submarines. Wearing this imitated "dolphin skin" on the submarine shell not only reduces the resistance during navigation by half, but also makes the navigation easier. The speed has also more than doubled.
