Humanity is in a state of constant development. Needs drive progress, and every year there are more and more of them. If initially the need was for food and a safe place to sleep, now the desires of a he althy individual, which must be satisfied, have exceeded several dozen. Science does not stand still. Constantly introduced some new items in different areas of human needs and his life. This is what the technology of the 21st century focuses on.
Entertainment
The technology described by writers long before its appearance is virtual reality. Of course, capsules in which the body will rest and the brain will see real dreams are far enough away. But already now you can see with your own eyes what is not there, and at the same time not get an appointment with a doctor. Augmented and virtual reality will become visible to anyone who purchases special glasses and installs the desired application on a smartphone.
What is the difference between these technologies:
- AR technology - augmented reality. Implies under the name of perception by the human brainartificial elements with special devices as an integral part of the world.
- VR technology. Creates a new reality, different from the present, with which the owner of technological innovations can contact and interact with the help of the senses. The new world is perceived visually. Sounds are heard, thanks to which a person using the technology is almost completely immersed in a virtual environment, feels everything as a real reality.
How to achieve total immersion in 21st century technology
In order to achieve the effect of full interaction with the artificial environment, various technologies are used. The simplest are smartphones with special functionality. Complex - retinal monitors that project elements of artificial reality directly onto the retina. For general use, virtual reality rooms can be launched. In them, the visitor achieves the maximum immersion effect by imitating smells and tactile sensations.
At the moment, all this 21st century technology is more entertaining. But projects have already been launched to create rehabilitation programs based on these technologies. Even in medicine, developments are now being used to transmit data through brain interfaces, although the technique is still too expensive for everyday use.
Production
3D printers have become a significant achievement in the field of manufacturing. This technology has become a lifesaver for those industries that require high-precision manufacturing of small parts,for example, circuit boards for smartphones, buttons, or small toys like those found in chocolate surprise eggs.
This 21st century technique has become popular not only in large-scale production, but also for home use. With the help of such equipment, they learned to build houses and set complex structures. On a 3d printer, they were even able to print the base for a motorcycle, not like simple decorative figurines.
Medicine
This section of science and technology of the 21st century should be considered separately. Over several decades, many milestones have been achieved here, dozens of technologies and operations have been created and simplified.
3D printer in medicine
Although initially this device was purely industrial in nature, its functionality has become indispensable in medical operations. 3D printing is used wherever possible, and its accuracy and capabilities are amazing. With the help of such a printer, it is possible to "print" dental implants, replace removed limbs and insert new bone. Of course, the material for such purposes is far from the plastic used for toys.
Once, for example, an American company introduced the technology of a new printer that allows printing human body tissues, blood vessels to replace "living" organs. Previously, attempts were made to grow and clone them based on stem cells, but now the bioprinter has become a wonderful alternative. Instead of ink, this amazing cell invention has the necessaryfunctionality, and a computer-controlled smart head arranges them in the right order. In Russia, experiments in this direction are carried out regularly, and their results are promising.
Artificial heart
Sure, artificial and mechanical hearts are often featured in cyborg movies or anime, but it's completely real now. Such hearts are full-fledged substitutes for real ones, but, unfortunately, they are temporary. This technology is used only when the patient is on the verge, and the “living” heart is not yet ready. Due to the lack of donor organs, this development has become life-saving: it helps the patient to wait for his own new organ and survive.
The best of these 21st-century advances is an organ built by a Massachusetts company called AbioCor. Its advantage was complete autonomy, that is, unlike other brothers, it does not need access to a power source, as well as tubes and wires passing through the skin. This almost completely eliminates the possibility of infection.
Exoskeleton
New foreign technologies are designed to help people with disabilities and are able to cure most of the patients. The main task of medicine of our time is to provide every person with a full existence at any age. But as a result of diseases of the nervous system, many people cannot lead a full life. An exoskeleton comes to the rescue. Now this amazing invention in the technology of the 21st century is mainly used only in Japan, but has already been recognized by the European Union. And soon in manyrehabilitation centers for patients will have similar developments.
Science does not stand still. Every day something unusual appears in the world. The new technology of the 21st century is already allowing people to get rid of many diseases and problems. The process of development cannot be stopped, it cannot even be slowed down. And therefore, every year there will be more and more new and useful things, and life will become much easier.
