Artificial muscles, as the name suggests, are artificially created muscle tissue similar to the human body.

The most advanced human-shaped robots or prosthetics are limited by bulky motors and hydraulic systems. Due to their flexibility, strength and overall working ability, they cannot achieve bionic hands as flexible as human palms.

Scientists are eager to find a breakthrough technology that can contract flexibly and independently like human muscle fibers and make various flexible movements.

Therefore, the scientific community has given birth to research ideas and directions for artificial muscles.

Research on artificial muscles first began in the 1940s, but it has been a recent 10-year period.

The birth of special polymer materials and smart materials in recent years has provided new development opportunities for the research of artificial muscles, and those new materials often have some extraordinary abilities.

Some materials can take various complex states according to current changes, such as bending, extending, twisting and contracting, etc., and their behavior is very close to real muscle fibers.

Currently, there are three major research centers around the world participating in the research of artificial muscles, two of which are in the United States and one in Switzerland, and both have nothing to do with China.

Various concept products related to artificial muscles are released every year, but none of these products are commercially available at present.

These concept products made from various new materials face many problems, such as consuming a lot of energy and may often fail to repair themselves like real muscles.

Either the shrinkage angle is poorly controlled and cannot complete the flexible movement of human fingers and torso, or the material shrinkage cycle life is very low and it is very durable.

Or the contraction strength is insufficient, and the actual effect is like a patient with muscle weakness, and he cannot bear real muscle function at all.

In general, the scientific community has not yet developed a truly perfect artificial muscle.

but!

Chen Changan has the most perfect set of electronically controlled artificial muscle technology!

Relevant technical information, Chen Changan handed it over to Li Yuntong as early as the establishment of the Bionic Prosthetic Project.

However, although the technical information is complete, scientific researchers also need time to figure out the technical principles and understand the key points before they can try to produce some trials.

It took more than a year or two tossing to the ground before the prosthetic body base trial-produced the first batch of artificial muscle fibers.

This artificial muscle is composed of bionic motor fibers, each of which is equivalent to the muscle fibers of the human arm.

These artificial movement fibers can independently perform bionic movements that are exactly the same as human muscles.

By superimposing hundreds of artificial bionic motion fibers, they become artificial muscles.

What powers these artificial muscles is naturally electrical energy.

However, in addition to electricity, it is also necessary to drive these artificial muscles to perform corresponding muscle movements.

That is the artificial neurons under the charge of Fu Yi’s project team!

The research and development of artificial neurons that Fu Yi is responsible for is actually similar to her work in the visual prosthesis device project.

However, what needs to be deciphered in the visual prosthesis device project is the genetic code of the optic nerve, while what needs to be deciphered in the bionic prosthesis project is the genetic code of the palm nerve tissue.

Of course, it would obviously not work for her to decipher a dozen people without any clues.

The relevant neural codes are still provided by Chen Changan. Fu Yi only needs to correspond to various bionic actions one by one, and then convert the nerve motion signals into electrical signals.

In this way, only a few nerve sensors and patches are needed to arrange at the connection between the bionic prosthesis and the human residual limbs to collect the motor signals released by the brachial plexus nerves and motor muscles at the end of the residual limbs, and convert them into electrical signals to conduct them onto the artificial nerves of the bionic prosthesis.

If you do this, when a patient who has lost his arms wears a bionic prosthesis, as long as he adapts a little, imagines his arms and palms still, and imagines what movements he has in his mind. After receiving the signal, the artificial nerves on the prosthesis will naturally drive the artificial muscles to move.

Theoretically, this driving method completely simulates the real reaction of a person. The actions made by the arms and palms will be exactly the same as the original arms, without any delay.

This is like the lost arm growing back again, without any obstacles.

Currently, bionic prosthetics on the market are controlled through a series of software control programs to control the prosthetics for movement instructions.

For Ottoboke and Oso, the most famous for making prosthetics, their bionic prosthetics can perform about twenty or thirty different finger linkage movements, as well as eight commonly used gesture movements.

For example, pinch, hold, hold, grab, etc. finger linkage, as well as gestures such as OK, 1.2.3.4.5.

However, their gestures and finger linkage are all based on software programming, and the programming instructions for these actions are set within the prosthesis.

What action a patient wants to do must first release a bioelectric signal, and then the product's induction patch collects the signal, then analyzes and processes the signal, and finally converts it into a specified action.

If it is an action that is not written on the prosthesis, it cannot be recognized and cannot be done.

It's like someone telling you that your hands can only do the thirty movements they prescribe, and you can't do other movements, and you can't do it anymore.

How uncomfortable it would be to use such a pair of hands?

Moreover, these movements are very slow and cannot be moved as you wish. It takes at least a few seconds to issue instructions from your mind and make movements from your fingers.

This is simply unbearable, so the bionic palms on the market basically do not have any commercial conditions.

However, Ruikang's bionic prosthesis is different. Ruikang's bionic prosthesis completely simulates the human brachial plexus nerve signal and muscle movement, and uses nerve signals to directly control the arm to respond.

It can be said that except that Ruikang's bionic prosthesis is not made of flesh, it is completely different from the human arms in other aspects. It has a complete nervous system and motor muscles, but they are all artificial, but they are exactly the same as the original ones.

It's even much better than the original ones.

Ruikang's artificial muscles are not only similar to human muscle fibers, but are elastic, and can stretch and contract with changes in ambient temperature and chemical composition, which can completely simulate the biological processes of living bodies.

It can also provide more than 85 times the lifting force of natural skeletal muscles, and its strength is much stronger than that of natural muscles.

It even has a circulatory system, where oxygen and electrical energy can be transported through the circulatory system, providing force to the muscle itself, and then performing mechanical actions.

It also has nerves, composed of special circuits, able to react and control its own behavior!

It can also store energy and directly judge and respond to contact like human muscles!

And through various high-precision sensors spread across the prosthesis, you can also feel the touch, pressure, and cold, and pass these data back to the terminal nerves of the residual limb.

For example, if an ice cube is placed on the prosthetic arm, the fingers of the prosthetic limb will become cold, and the patient's nerves will receive signals, and will feel the coolness and generate perception.

As long as this bionic prosthesis is installed, the patient will not feel any incongruity, and the experience is exactly the same as the original limbs!
