From fireflies to artificial cold light.
Since the invention of electric light, life has become much more convenient and richer. But electric light can only convert a small part of the electrical energy into visible light, and most of the rest is wasted in the form of heat, and the heat rays of electric lights are harmful to the human eye. So, is there a light source that only emits light but does not heat up?
Humanity has turned its attention to nature again.
In nature, there are many organisms that can emit light, such as bacteria, fungi, worms, mollusks, crustaceans, insects and fish, etc., and the light emitted by these animals does not produce heat, so it is also called "cold light".
Among the many light-emitting animals, fireflies are one of them. There are about 1,500 species of fireflies, and the colors of their cold light range from yellow-green to orange, and the brightness of the light varies. The cold light emitted by fireflies not only has a high luminous efficiency, but also the cold light emitted is generally very soft, which is very suitable for human eyes, and the intensity of the light is relatively high.
Therefore, biolight is a kind of light that is ideal for human beings.
Scientists have found that the glowing device of the firefly is located in the abdomen. This luminaire is composed of three parts: a light-emitting layer, a transparent layer and a reflective layer. The luminescent layer has thousands of light-emitting cells, and they all contain two substances, luciferin and luciferase.
Under the action of luciferase, luciferin fluoresces when it is oxidized with the participation of intracellular water. The luminescence of fireflies is essentially the process of converting chemical energy into light energy.
Back in the 40s, fluorescent lamps were created based on the study of fireflies, which changed the source of human lighting a lot. In recent years, scientists have isolated pure luciferin from the luminescent device of fireflies, and later isolated luciferase, and then chemically synthesized fluorescein. A biological light source composed of a mixture of luciferin, luciferase, ATP (adenosine triphosphate) and water, which can be used as a flash lamp in mines filled with ** gas.
Since this light has no power source and does not generate a magnetic field, it can be illuminated by a biological light source to remove magnetic mines.

1.The glider was made on the basis of a gliding bat.
2.People imitate the honeycomb structure with a variety of materials to make honeycomb sandwich structural panels, high strength, light weight, not easy to conduct sound and heat, is the ideal material for the construction and manufacture of space shuttles, spaceships, artificial satellites, etc.
3.In an emergency, the spider's thigh will be filled with fluid and the leg will turn from soft to hard, bursting out of force and jumping up, bionic scientists imitate this wonderful hydraulic leg to develop a walking machine.
4.The helicopter was designed according to the Dragonfly.
5.The electronic eye was designed based on the frog's eye.
6.Suction cups are designed according to the antennae of the starfish.
7.Sonar was designed based on dolphins.

1。Flies, successfully imitated a very peculiar small gas analyzer. It has been installed in the cockpit of a spacecraft to detect the composition of the gases in the cabin.
2。fireflies to artificial cold light;
3。Electric fish with volt batteries;
4。The downwind ears of jellyfish, imitating the structure and function of jellyfish ears, designed the jellyfish ear storm instrument, which can predict the storm 15 hours in advance, which is of great significance to the safety of navigation and fishery.
5。The visual principle of frog eyes has successfully developed an electronic frog eye. This electronic frog eye can identify objects of a specific shape with the same accuracy as a real frog eye.
After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved. This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.
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 can issue an alarm if it detects that the aircraft is about to collide. In the traffic arteries, it can direct the driving of vehicles and prevent the occurrence of vehicle collisions.
6。The principle of the bat ultrasonic locator, people also imitate the "pathfinder" used by the blind. This pathfinder is equipped with an ultrasonic emitter that a blind person can carry to spot people on electric poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.
7。An incomplete photosynthesizer that mimics cyanobacteria will be designed to bionic photolyzed water, so that a large amount of hydrogen can be obtained.
