Biomimicry essay, essay on biomimicry

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.

Nowadays, it is possible to obtain cold light similar to biological light by mixing certain chemicals, which can be used as safety lighting.

Downwind ears of jellyfish.

Swallows fly low to make the rain, cicadas chirp in the rain, and the sky is clear. "The behavior of living things has something to do with changes in the weather. Coastal fishermen know that the fish and jellyfish that live along the coast swim to the sea in droves, which is a sign that the Mintanjan storm is coming.

Jellyfish, also known as jellyfish, is an ancient coelenterate that floated in the ocean as early as 500 million years ago. This lower animal has the instinct of a storm, and whenever a storm comes, it swims to the sea for refuge.

It turns out that on the blue ocean, infrasound waves (frequency 8-13 times per second) created by the friction between air and waves are always a prelude to the coming of a storm. This infrasound cannot be heard by the human ear, but the tiny jellyfish is very sensitive. Biomimicists found that the jellyfish ear has a thin stalk in the resonance cavity, a small ball on the handle, and a small listening stone in the ball, when the infrasound wave before the storm hits the listening stone in the jellyfish's ear, the listening stone stimulates the nerve receptors on the bulb wall, so the jellyfish hears the rumbling sound of the approaching storm.

Biomimicists imitate the structure and function of jellyfish ears and design the jellyfish ear storm instrument, which quite accurately simulates the organs of jellyfish that sense infrasound waves. Installed on the foredeck of the ship, this instrument can cause the horn to rotate 360° to stop rotating when it receives the infrasound wave of the storm, and the direction it points to is the direction in which the storm is going; The readings on the indicator tell you the intensity of the storm. This instrument can make a forecast of storms 15 hours in advance, which is important for the safety of navigation and fishing.

The eyes of a frog.

Imitating spruce to build a sweet potato rental radio and television hand vertical station.

The rattlesnake's peculiar amenous amenous function led to the development of night vision devices.

The sentence is a praying mantis arm or sawgrass.

The radar was set up according to the eyes and ears of the bats.

Wonderful imitation bai

The world of biomimicry.

How wonderful it is. zhi

According to the annoying fly dao

Imitation success of a specialty.

A very peculiar small genus gas analyzer. It has been installed in the cockpit of a spacecraft to detect the composition of the gas in the cabin; According to the visual principle of frog eyes, people have successfully developed an electronic frog eye.

This frog eye can identify objects of a specific shape with the same accuracy as a real frog eye; There is also the invention of the "streamlined body" according to the whale, which reduces the resistance of the ship in the water and greatly increases the speed of the ship's sailing; People also built many buildings that were both light and material-saving based on the characteristics of the egg's "thin shell structure"; In addition, people imitated kangaroos to build jumping off-road cars, and certain shells to make tanks with sturdy shells.

There are many creatures around us that can be inspired by research. Through the study of animals and plants, we can develop more advanced items to improve our lives.

The world of biomimicry is amazing!
