The twenty-first century brought with it new technologies that helped bring to life previously impossible and unusual inventions. These discoveries include:
- artificial retina;
- projection keyboard;
- electronic cigarette;
- brain interface;
- use of digital cameras in mobile phones;
- digital scent synthesizer;
- electronic paper;
- portable nuclear reactor;
- desktop 3D scanner;
- artificial chromosome;
- smart chopsticks;
- nanorobots.
Since even less than a fifth of a century has passed, most likely, the most unusual inventions of mankind, developed and created in the future, are ahead of everyone. To date, open novelties show what technical progress has reached and what previously unknown opportunities a person can use.
Let's take a closer look at some of the unusual inventions of man, created at the beginning of the twenty-first century.
Artificial retina
This discovery belongs to Japanese scientists. The produced retina is an aluminum matrix, where silicon semiconductor elements are used. 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 a computer, where processing takes place. The camera in the glasses converts light into portions of electronic impulses. After processing the image, the computer divides it in half and transmits it to the left and right eyes, to infrared emitters located on the back of the lenses of the glasses. The glasses emit short pulses of infrared radiation that activates photo sensors on the retina of the eye and causes them to transmit electrical impulses encoding an image to optical neurons.
In the future, it is planned that such a retina will be able to restore sight to a blind person and help to see smaller objects.
Later, Japanese scientists were able to grow the retina from mouse stem cells, testing is still pending.
Projection keyboard
Over time, more and more inventions appear. Unusual finds are present in human life, one of them is a projection keyboard.
With its help, it becomes possible to project keys onto the surface, where they are pressed. The video projector that projects the keyboard has a sensor capable oftrack the movements of the fingers, after which it calculates the coordinates of the keys pressed and displays the correctly typed text on the display. However, such a keyboard also has disadvantages, it cannot be used outdoors.
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. Whatever a person who quits smoking does. He tries to replace this habit with something else, like sticking a nicotine patch, buying gum, trying to find an alternative to smoking.
An electronic cigarette is a device that simulates smoking. When using such a novelty, a person does not give up his habit, does not look for replacements, but usually spends time. However, the smoker does not spoil his lungs with poisonous tar and combustion products, since they are absent in this type of device. Thus, a person who smokes an electronic cigarette can get rid of nicotine addiction.
Brain interface
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. A man used his mind to switch a switch on a model train of a large-scale railroad.
Principle of action: in the infrared spectrum, transillumination and filming of the cerebral cortex occurs. When carrying out such a procedure, the passage of hemoglobin through the vessels both with and without oxygen is clearly visible, while the volume of blood indifferent parts of the brain. The machine translates such changes into voltage signals that control external devices. This is how the train switch is controlled.
The project plans to achieve a more complex decoding of changes in the human brain. Receiving execution signals will be the pinnacle of human-machine interface development.
Digital scent synthesizer
Today no one is surprised by 3D sound or 3D video. Today, these are quite popular inventions. Unusual technologies entered our lives at the beginning of the 21st century. The French company presents its digital odor measurement solution. The emergence of such a novelty has brought diversity to the "digital life" of society. A variety of scents will be synthesized from cartridges. It will add zest to watching movies and video games.
E-paper
It is the same as electronic ink. Information is displayed on a special display. E-books use electronic paper, and it is also used in other areas. Reflected e-ink can display graphics and text for a long time without consuming much power.
Advantages of this paper:
- energy saving;
- this type of reading does not burden the eyes, like regular paper, and therefore does not damage human vision.
E-paper can reflect video at 6 frames per second,transmits 16 shades of gray.
Work continues to improve this invention and increase the display speed.
Desktop 3D scanner
The principle of operation of such a device is to use two cameras, the image from which is formed and compared. With the help of such a scanner, accurate three-dimensional models of the necessary objects are created. They are reflected with maximum accuracy of various details. Information is transmitted in mathematical, computer and digital form, carries data on the size, shape, color of the scanned element.
The picture settings are controlled by the computer. All received data is 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 "smart" chopsticks to the attention of the audience. The essence of this invention is that when chopsticks are immersed in food, information about the quality of food is displayed on the screen of the gadget on which the necessary application is installed. That is, by dropping, for example, chopsticks into oil, you will see a message “good” or “bad” on the screen, based on the quality of the product being checked.
The situation with products in China prompted scientists to release such an invention. Many diseases have been identified in the country precisely because of the consumption of poor-quality food. Often, foods are cooked in the same oil, which leads to toxic substances in it.
Smart sticks canshow:
- oil freshness;
- pH level;
- fluid temperature;
- fruit calories.
Manufacturers are going to expand the capabilities of sticks so that they can be used to determine more indicators of food intake. This invention has not yet been released to the public market, as it is not yet mass-produced.
Invention: nanorobots
Today, many scientists are striving to create nanorobots - machines that can work at the atomic and molecular levels. Such an invention will enable the production of 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, fuel and participate in other processes that ensure human life. Such robots will be able to create themselves.
Nanotechnology is a symbol of the future and one of the vectors of civilization development. Their use is possible in almost all spheres of human life.
In medicine, the emergence of nanorobots will lead to a complete cure of the human body. They can be launched into the body. Properly programmed machines will begin to destroy viruses and other harmful substances that are inside the body. With the help of nanotechnology, it is possible to give a beautiful and he althy look to human skin.
In ecology, electronic machines will help stop the pollution of the planet. With their help, it will be possible to purify water, air and other vital sources of human he alth.
Suchunusual inventions of mankind can help solve complex problems, but at the moment the development is at the research stage.
To date, some components of future molecular machines have been created, various conferences are being held on the issue of creating nanorobots.
There are primitive prototypes of future machines. In 2010, DNA-based molecular machines were shown for the first time that can move through space.
The world of nanotechnology does not stand still, and perhaps the 21st century will still 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 virtual pages in the World Social Networks. Therefore, we can say that unusual inventions created by one's own hands are social networks.
The development of technology leads to a decrease in real meetings and more inclination towards virtual communication.
New virtual inventions, whose unusual functions help a person to 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 facts of interest to them.
- Oculus Rift is a video game website.
- Apple iPhone is a phone that has access to the Internet. It is also possible to watch movies, listen to music, dophotography, video recording. The phone also performs many other useful functions, including the classic one: chatting with friends.
- Amazon Kindle is an electronic book library.
Conclusion
Inventions are stupid and smart, useful and not very useful. However, every year the unusual inventions of the world are improved, against the background of some, others develop. Mankind strives to invent something extraordinary that will surprise everyone. At the same time, the novelty should bring convenience to people's lives, make life easier for a person in some way.
The 21st century will still bring new inventions, unusual opportunities, thanks to which humanity will be able to explore previously unexplored spaces and acquire new knowledge.
