Many technologies in the world today are rapidly evolving. The difference between the technological devices of 20 years ago and today’s devices is like heaven and earth. Many of us are interested in technology, such as computers, smartphones, apps, as well as technological applications that we do not care about; there has been a huge improvement in the past. So today, we are talking about something that even those who are interested in technology usually forget.
There is a clear reason why we should not think about artificial limbs. That is, we who have good hands and feet never think we need them. But anyone who is born without them or wants to live because of an accident or illness may reluctantly have to adapt to a life without one or more of them. Just think, if you lost your hand, would you be able to do the job, education, and day-to-day work you currently do?
For those who find such a situation, these technologies are worth a fortune. As soon as we hope that such a thing does not happen to anyone, let us know how the solutions for someone who has faced such a situation are expanding.
We are only talking about external organs here. In the next article, we will talk about the internal organs and the prostheses that help other than movement.
Artificial limbs are not new
Losing organs for a variety of reasons is not new to humans. There is ample evidence that past wars, regimes, and ignorance of nature led to a much higher organ loss rate than today. In the past, technology may not have been advanced, but it was possible to find an alternative in a sense.
Despite losing a limb due to various accidents, they developed prostheses that made it easier to carry on with their work and daily activities. Artificial limbs were later used to hide the fact that there was no organ or reduce the imbalance caused by it.
These non-mechanical prostheses are still widely used in our country due to their relatively low cost. These are less useful and more functional than passive organs in the past. But what is still being seen in many countries today are active artificial organs that can mechanically help the body function. Today, 3D printing, or 3D printing, is a great opportunity to cheaply make these expensive ones.
Activation of active artificial organs
Active prostheses are artificial limbs that can be controlled and shaped, and manipulated by the person who can fit them in some way. This ranges from the artificial hand, which can grasp something like a claw, to the most complex organs that can function similarly to a normal hand through neural messages coming from the brain.
Electric motors for mechanical work mainly power these. Very small, high efficiency, low heating, long-lasting, good power motors are used for this. Also important is the ability to rotate a part of a circle or stop at a certain angle. So stepper motors or servo motors are used for this.
Using somewhat simpler or more complex levers, rods, cables, and other mechanical devices, the motors’ rotation changes are converted into mechanical movements.
It is powered by high-quality lithium-ion batteries that can be easily stored in the body, small in size, light in weight, good power, and long-lasting power.
The other part is identifying what the person wearing the prosthesis needs directly from the brain, either directly through the nerves or through changes in the muscles of the body. Just move your fingers and see how the muscles in the lower part of the elbow of the arms change.
These prostheses contain a small control unit and software that can take commands through these movements and make various motor functions as needed. Going beyond that, advanced organs include advanced software that can accurately transmit electrical signals received through various nerves in the body and highly sensitive sensors to do all this successfully.
No special training is required to control these expensive neurotransmitters. But it takes some training to change muscles, like learning to operate a new backhoe for organs that function through muscle changes.
Ease of use of materials and 3D printing
In the past, most of the materials used for this purpose were easily found, such as strong, lightweight wood and animal bones. Later, lightweight, reinforced titanium and alloys, including alloys, special plastics, and fiberglass, were used. Currently, carbon fiber and other composites are widely used. However, using this ingredient in artificial limbs is expensive. There is a good chance that 3D printing will give you some answers. It has already become a reality.
3D printing involves printing a large number of thin layers, one at a time, as we would with a typical printer. Today this has become pretty much a cheap thing. It can be easily shaped into the desired shape without the need for a large number of machines or molds, including lathes, milling machines, and grinders. Not only this, with the help of computer-aided CAD designs can be printed directly, but this is a very advantageous method in terms of price.
Therefore, the price of these organs is likely to be very low in the future.
Will there be super people in the future?
All of this will give disabled people real need and those with diseases such as paralysis a better chance of getting active artificial limbs at a lower price in the future. Advances in technology will lead to the development of organs that can function better than normal human organs in the future. Just think about a driver who can surpass the fastest man in the world with two prosthetic legs.
As a result, there will be a tendency to have artificial limbs in the future, even if they are deliberately injured or outside the limbs without a real injury. Highly capable, they will be able to do things that ordinary people would not be able to do, just like the superheroes we see in fiction today.
With all of this, there is a great possibility that various rules and regulations will arise in the future and various problems. Some time ago, it was thought that these were just fiction, but today there are many reasons to think that it is not so far away.
