5 important inventions that

Many innovations and inventions are being used daily by humans from the models available in nature.

From the early days with stone tools to modern science and technology, people have evolved a lot, and also created many inventions to improve their lives.

And in fact, not every invention comes from the human brain.

The following are five important inventions, which are being used in everyday life, and are "learning" from things available in nature.

1. Velcro - learning from burdock

Swiss engineer George de Mestral observed that the burrs of the burdock clung to the pants as well as the dog's fur after a hunt and discovered that very small hooks on the seeds of this plant allowed them to cling. into fabric fibers easily.

Since then, with more than a decade of research and development, this engineer has produced an "artificial burdock" version he called himself "lock without lock". Later, this type of velcro is popular all over the world and is known for a modern name rather than Velcro.

2. SONAR - is similar to the contact ability of dolphins

Dolphin.

SONAR (reflected sound waves) , techniques for using sound waves to measure distances, create topographic maps and normal navigation, are used in a wide variety of vehicles, modern military military equipment. Now, very similar to the ability to communicate by sound waves of dolphins.

This system was invented by French physicist Paul Langevin in 1915.

3. Enlightenment - artificial version of octopus tentacles

Using the principle of vacuum and air pressure, this tool helps us to stick objects to a flat surface and can be used repeatedly. Sensory suction is officially recognized as a patent in 1860 and is currently widely used in many fields.

Suction is widely used in human life.

In nature, octopus tentacles are a much more advanced version of artificial suckers. The small concentric grooves on the sides of the tentacles allow the octopus to capture objects even when the surface is not flat and underwater.

4. Super speed boat - thank the kingfisher

The first super-fast ships were designed with a spike similar to the nose of a grand master. But then, through the testing process, it was discovered that such a design had a huge disadvantage: noisy.

With a bullet-like tip, the bullet train will emit noises like thunder when escaping from tunnels.
Japanese Railways engineer Eji Nakatsu brought the high-speed train design similar to the actual kingfisher structure. This structure not only reduces the noise but also helps the ship to move stably, save fuel and allow movement at higher speeds.

5. Light bulbs are brighter - thanks to fireflies

On LED models, a portion of the light on the exit of the lamp housing has been reflected back in, thus reducing lighting efficiency.

To overcome this problem, a team at the University of Sherbrooke, Canada, studied the glowing tail section of fireflies and discovered the special structure of this tail to apply to existing LED bulbs. great.

Instead of making the surface of the lamp flat and smooth, one creates a surface with exposed "scales" with a tilt and layered structure to ensure complete light transmission.

High-class LED lamps now study this layered "model" of fireflies to create 1.5 times the lighting capacity of lamps with smooth surfaces.
