How soon prostheses will acquire all functions of real limbs 2 октября, 2021

Modern prostheses are well coped with the seizure of objects, but still not sufficiently accurate in the transfer of information from the limbs to the brain. The functions of touch and gesticulation remain poorly developed even in the newest bionic inventions, but scientists try to fix it. How many years left and still go to the creation of the first prosthesis with all the functions of the real hand, read further.

The first documented fact of use by a functional prosthetic man belongs to the Roman General Mark Sergia Esquilin, who kept the shield by iron hand. After the 25th centuries, the functionality of prosthetics increased, but only in 2007 prototypes of tangible (capable of sensitivity) of artificial limbs appeared.

During the conversation on the phone, people involuntarily gesticulate with their hands, although the interlocutors do not even see each other. The body language is an integral part of the expression of thoughts that people with prosthetated hands cannot take advantage. Undoubtedly, this affects the full expression of a person’s personality.

It is this problem that they want to decide in the laboratories of Ras Labs, where for more than 13 years they have been studying the possibility of creating a maximum realistic prosthesis, which will not only be functional, but also sensitive. The founder of the Ras Labs Labs Lenor Rasmussen caught fire up with this idea 20 years ago and is now forced to state that for realial achievement the goal is necessary new, another unknown way: «I thought that there should be a way to overcome the gap between the form and the function, another method of performing movement, and Not a purely mechanical approach. «

Therefore, it investigated the class of «smart» materials, called electroactive polymers, which are not only much easier than metals, but also capable of converting electrical potential energy into a mechanical movement without gears or engines.

The laboratory found and patented specific compositions and configurations of polymers, which can actually decline, like human muscles. Now they are used in the product called Synthetic Muscle — muscles with the possibility of biomimetic movement. Biomimetics are materials that are created on the principles of wildlife and are able to accurately imitate the properties of biomaterials. In the case of artificial hands, this dexterity, stretching, bends and compression.

It is important to note that Ras Labs seeks to produce these prostheses without high energy requirements. This factor is crucial for their availability and widespread use, since in addition to functionality, an acceptable price is equally important.

In order to determine if the invention can function RAS Labs to function in unsuitable conditions for humans, electrically conductive polymers were constantly tested in different critical situations. It all started with cooling to -271 ° C, after which the effect of strong pressure and shock shock was tested. Then scientists moved to radioactive tests with cesium, but it was not enough. The new stage involves the test of Synthetic Muscle in space.

Tests at the International Space Station will help determine whether it is possible to send robots using Synthetic Muscle in environments in which people cannot be for security reasons. Robot emergency response can save many lives in situations that are too dangerous for a person, for example, at nuclear power plants.

Test results can help identify the strengths and weaknesses of specialized polymers. In addition to passive exposure, the effects of lack of gravity will be investigated. Synthetic Muscle is expected to change behavior inside the materials or even their structure. The behavior includes chemical, thermal, physical, electrical and magnetic characteristics.

The listed effects occur mainly due to differences in fluid dynamics in space. For example, removal of sediment or convection due to buoyancy. In the absence of these phenomena, scientists can identify the main characteristics of the materials and find the keys to control their properties, which otherwise could never be detected or understood during ground research.

In Ras Labs, they hope that the perfect material will be found within 5 years to create a completely tangible prosthesis.

In 2018, researchers from the University of John Hopkins reported testing synthetic skin called

«The pain, of course, is unpleasant, but it is also an important protective feeling of touch, which is not in the existing prosthesis at present,» says Man without hand Luke Osborne. Scientists argue that the feeling of pain can be very useful for foot prostheses that experience overload and may be damaged even without the owner’s knowledge. In addition, it is possible to adjust the power of pain manually, since E-Dermis needs to be customized for each person separately through a series of tests.

The operation of the prosthesis is based on the method of subcutaneous stimulation of electric nerve, as well as monitoring the brain activity to determine signals corresponding to specific sensations. At the moment, E-Dermis remains a prototype that requires refinement.

Despite the importance of sensitive skin prosthesis, its strength is no less significant. Scientists from Illinois University last year presented to the world

The composition of the invention did not cost without polymers, in addition to which carbon fibers are performing. The mechanism of electric shock is started. The tests have shown that the thread created in this way of 1.6 g is able to raise the weight of 1.9 kg.
