Successfully developing artificial muscles like real ones, being able to reproduce themselves

Not only artificial skin or prostheses, scientists have now created artificial muscles for humans.

It can be said that muscle groups on the body are one of the most important functions. It can stretch under human requirements, stretch without hurting and even recover when injured. Previously, studies of artificial muscle groups could not keep up with the real ability of muscles in humans. However, researchers now say they are about to succeed in making artificial muscle groups with the same ability to operate as humans.

The new polymer material has a self-healing ability to stretch many times more than its original size.

In a new discovery, the Stanford research team described its invention with a super-elastic and self-healing polymer. This material is believed to be used to make artificial muscle. It can stretch 45 times the actual size and return to the old shape immediately. This feature is superior to many similar materials many times. In addition, it can also restore wounds at extremely low temperatures . This is also the remarkable ability of new artificial muscle compared to previous products.

But what makes it such a biomedical breakthrough?

In the 2000s, many scientists found that polymers such as plastics could stretch up to three times the actual length and many other polymers can recover themselves. However, up to that point, no one has been able to combine both features in the same product. This is a key point in creating artificial muscle groups that have the same power as humans.

This scientific advance comes from a new innovation in a chemical bonding process called crosslinking . The polymer is made up of chains of linked molecules, rearranged as a chain barrier. These chains are like wires connected together by elastic bands. Therefore, they are capable of moving around. This new product is an important improvement with the ability to stretch stretches, besides the inherent self-recovery feature.

Creating artificial muscle groups has long been the dream of many scientists.

However, new products still have many limitations to be applied in practice. For example, under certain conditions, they cannot stretch as desired. Therefore, the flexibility will be less than the natural muscle group of humans.

The team of scientists is also working to produce artificial skin products. If successful, the two new materials will help replicate and develop prosthetics with the same ability as parts of the human body.
