What inventions did the 21st century give us?

The twenty-first century brought with it new technologies that helped bring to life previously impossible and unusual inventions. Such discoveries include:

• Artificial retina of the eye;
• Projection keyboard;
• Electronic Cigarette;
• Brain interface;
• Use of digital cameras in mobile phones;
• Digital odor synthesizer;
• Electronic paper;
• Portable nuclear reactor;
• Desktop 3D scanner;
• Artificial chromosome;
• "Smart" chopsticks;
• Nanorobots.

Since even less than a fifth of the century has passed, it is most likely that the most unusual inventions of mankind, designed and created in the future, are waiting for everyone. To date, open innovations show how technical progress has reached and what previously unknown opportunities people can use.

Let us consider in more detail some of the unusual inventions of man, created at the beginning of the twenty-first century.

Artificial retina of the eye

This discovery belongs to the Japanese scientist. Produced retina is an aluminum matrix, which uses semiconductor elements made of silicon. The resolution is 100 pixels.

The retina will perform its functions if it was installed complete with special glasses and a small computer. Glasses with a built-in video camera are used to receive and transmit images to the computer, where the processing takes place. The camera in glasses converts light into portions of electronic pulses. After processing the image, the computer divides it in half and transfers it to the left and right eyes, into the infrared emitters located on the back of the lens of the glasses. The glasses emit short pulses of infrared radiation, which activates the photosensors on the retina of the eye and causes them to transmit the electrical impulses that encode the picture into optical neurons.

In the future, it is planned that such a retina can restore sight to the blind person and help to see smaller objects.

Later, Japanese scientists were able to grow the retina of the eye from stem cells of mice, its testing is not yet complete.

Projection keyboard

Over time, more and more inventions are emerging. Unusual findings are present in human life, one of them is a projection keyboard.

With its help, it becomes possible to design the keys on the surface, where they are pressed. The video projector that projects the keyboard has a sensor capable of tracking finger movements, then calculates the coordinates of the pressed keys and displays correctly typed text on the display. However, such a keyboard has drawbacks, it can not be used in nature.

Electronic Cigarette

This discovery was made by a Chinese scientist, after his father died of lung cancer. Nicotine addiction is one of the strongest in the world. What only does a person quitting smoking. He tries to replace this habit with something else, for example, glues a nicotine patch, buys gum, tries to find an alternative to smoking.

Electronic cigarette is a device by which the process of smoking is simulated. When using such a novelty, a person does not give up his habit, does not seek replacements, but usually spends time. However, the smoker does not spoil his lungs with poisonous tar and combustion products, since they are not present in this kind of device. Thus, a person who smokes an electronic cigarette can get rid of nicotine addiction.

Brain Interface

The unusual inventions of the 21st century are quite diverse, and one of them is the brain interface.

An example of controlling objects with thought was demonstrated by a Japanese company. The man forced the switch, installed on the model of a large-scale railroad train, to switch by force.

Principle of action: in the infrared spectrum, X-ray of the brain takes place. With this procedure, it is easy to see the passage of hemoglobin along the vessels with or without oxygen, and the volume of blood in different parts of the brain is also seen. Such changes the machine translates into voltage signals that control external devices. This is how the train switch is controlled.

In the project it is planned to achieve more complex deciphering of changes in the work of the human brain. Obtaining execution signals will be the pinnacle of the human-machine interface development.

Digital odor synthesizer

Today, no one is surprised by 3D-sound or 3D-video. To date, these are quite popular inventions. Unusual technologies entered our life in the early 21st century. The French company presents its solution to the digital measurement of odors. The appearance of such a novelty brought variety to the "digital life" of society. A variety of odors will be synthesized from the cartridges. This will add zest to watching movies and video games.

Electronic paper

Represents the same as electronic ink. The information is displayed on a special display. Electronic books use electronic paper, and it is also used in other areas. Electronic ink in reflected light can display graphics and text long enough without spending a lot of energy.

Advantages of this paper:

• Energy saving;
• This kind of reading does not load the eyes like ordinary paper, which means it does not damage the person's vision.

Electronic paper can reflect a video at a rate of 6 frames per second, transmits 16 shades of gray.

Work continues on improving this invention and increasing the speed of the show.

Desktop 3D scanner

The principle of operation of such a device consists in using two cameras, the image of which is formed and compared. Using this scanner, accurate 3D models of the required objects are created. They are reflected with maximum precision of various details. The information is transmitted in mathematical, computer and digital form, carries data about the size, shape, color of the scanned item.

Using the computer, the image settings are controlled. All received data are analyzed, and the image appears on the screen already in three-dimensional space.

Smart Chinese chopsticks

One of the Chinese companies in the twenty-first century presented the audience with "smart" chopsticks. The essence of this invention is that when you immerse the chopsticks in food on the gadget screen on which the necessary application is installed, information about the quality of food is reflected. That is, dropping, for example, sticks in oil, you will see a message on the screen "good" or "bad", based on the quality of the product being tested.

To the release of such an invention, scientists pushed the situation with products in China. In the country, many diseases have been identified precisely because of the consumption of poor-quality food. Often the products are cooked on the same oil, which leads to the appearance of toxic substances in it.

Smart wands can show:

• The freshness of the oil;
• PH level;
• Temperature of the liquid;
• The amount of calories in the fruit.

Manufacturers are going to expand the capabilities of sticks, so that they can be used to determine a greater number of indicators of food intake. This invention has not yet been released in an affordable sale, since mass production is not yet underway.

Invention: nanorobots

To date, many scientists are trying to create nanorobots - machines that can work at the atomic and molecular levels. Such an invention will make it possible to produce molecular materials. It will be possible, for example, to make oxygen or water. Also in the economic sphere, they will be able to create food products, fuel and participate in other processes that ensure human life activity. Such robots can create themselves.

Nanotechnology is a symbol of the future and one of the vectors of the development of civilization. Their use is possible in virtually all areas of human life.

In medicine, the appearance of nanobots will lead to a complete cure of the human body. They can be run into the body. Correctly programmed machines will begin to destroy viruses and other harmful substances that are inside the body. With the help of nanotechnology, you can give a beautiful and healthy look to a person's skin.

In the environment, electronic machines will help to stop pollution of the planet. With their help, it will be possible to purify water, air and other vital sources of human health.

Such unusual inventions of humanity can help in solving complex problems, but at the moment the developments are at the research stage.

To date, some components of future molecular machines have been created, various conferences have been held on the issue of creating nanorobots.

There are primitive prototypes of future machines. In 2010, for the first time, molecular DNA-based machines were shown that can move in space.

The world of nanotechnology does not stand still, and perhaps the 21st century will be called the century, in which the most unusual inventions will appear.

Virtual world

The new century brought with it virtual communication, dating, games. A person builds his own horizons, creates his own virtual pages in the World Social Networks. Therefore, it can be said that unusual inventions, created by oneself, are social networks.

The development of technologies leads to a decrease in real meetings and more inclines to virtual communication.

New virtual inventions, whose unusual functions help people adapt in a virtual society, are:

• Facebook is a social network where people from all over the world can communicate. Share photo and video novelties, discuss, advise, tell various interesting facts.
• Oculus Rift is a website dedicated to video games.
• Apple iPhone is a phone that has an Internet connection. Also, you can watch movies, listen to music, take photos, and record video. The phone does a lot of other useful functions, including classical: conducting conversations with friends.
• Amazon Kindle - e-library of books.

Conclusion

Inventions are stupid and clever, useful and not very useful. However, every year the unusual inventions of the world are being improved, against the background of others, others are developing. Humanity strives to invent something extraordinary that will surprise everyone. At the same time, the novelty should bring convenience to people's lives, facilitate in some way the life of a person.

The 21st century will still bring new inventions, unusual opportunities, thanks to which mankind can learn not previously known spaces and acquire new knowledge.
