Chapter 153 Artificial Skin and Robots

After that he went to the skin rejuvenation group next door.

This group was supervised by Xia Zhi and Sun Shiliang, hoping to save Ye Lihai who was suffering from burns.

After Ye Lihai's surgery, he still faces a huge challenge in the follow-up, that is, the skin cannot regenerate.

Apart from Ye Lihai, tens of millions of people in the world suffer from skin diseases.

Most of these skin diseases can be cured with skin grafts.

So Xia Zhi promotes the development of this skin regeneration group as soon as possible.

The person in charge of the group introduced the technology they are currently using to Xia Zhi:
"The endogenous skin regeneration therapy we are researching comes from Switzerland and is CE certified by the European Union. The therapy uses its own blood to prepare a stock solution rich in high-concentration growth factors in just one and a half hours, and inject it into the skin tissue on the spot , to ensure its biological activity, regenerate the whole layer of the skin, use its own power to produce a large amount of collagen and elastic fibers, repair damaged skin, and restore the skin's delicate luster, elasticity and firmness to a young state."

Xia Zhi asked:

"Technology from Switzerland?"

The person in charge nodded:
"In the early 90s, Swiss medical scientists had begun systematic clinical research on platelet-rich plasma. In the mid-90s, the Swiss National Laboratory successfully applied PRP technology to various surgeries, burns and Dermatological treatment.

In 2003, the Swiss National Laboratory successfully developed the improved PRP technology, which is the first generation of endogenous skin regeneration. Up to now, it is the third generation of endogenous skin regeneration. "

Afterwards, the person in charge showed Xia Zhi another research direction in the group: artificial skin.

Artificial skin is a skin substitute artificially developed in vitro by using the principles and methods of engineering and cell biology. It is used to repair and replace defective skin tissue. According to different components, it can be divided into pure artificial dermis and those with epidermal cell layer activity. Composite leather.

At first, the method of skin transplantation was to "remove the east wall and repair the west wall", that is, take the healthy skin from the patient and transplant it to the burnt part, but this method will cause new scars.Moreover, if it is a large area of ​​burns, there is not much normal skin left, it is really "all holes, not enough bricks".

This is the case of Ye Lihai, who suffered 90.00% burns all over his body.

In addition, people have used cadaveric skin or xenogeneic animal skin such as pigs as temporary wound coverings, but graft rejection often occurs.

Under this situation, research on artificial skin came into being.

Xia Zhi followed the person in charge to see several artificial skins being researched.

The first is the skin produced by researchers extracting protein from silk, called silk skin.

Xia Zhi was very surprised when he saw it, and he said:
"The quilt in my house is a silk quilt. I didn't expect that this silk could be used to make skin."

The person in charge explained with a smile:

"This artificial skin is like a clothing fabric made of silk, with silk-like smoothness and flexibility.

Moreover, it is safer than pigskin, currently the most commonly used material for treating large-scale injuries. "

Xia Zhi nodded.

The person in charge took out some samples of this new type of artificial skin and showed it to Xia Zhi.

Xia Zhi looks like wonton wrappers at first glance, but it is very resilient when pulled by hand.

The person in charge introduced:

"Take it out of the refrigerator, thaw it naturally, sterilize and soak it, stick it on the surface of the wounded skin, and the wound will heal slowly in about half a month."

Xia Zhiduo glanced at the 'wonton wrapper' in his hand, and said in surprise:
"Is it so amazing?"

The person in charge brought a test report, which recorded that the researchers selected 15 white rabbits and divided them into 5 batches for animal experiments. After the artificial skin was pasted, the wounds with a diameter of 3 cm on the rabbits healed in less than 20 days.

The more Xia Zhi looked at it, the more miraculous it became.

He nodded:

"Yes, it's a good project."

The person in charge said with a smile:

"There's more to come, Mr. Xia, follow me."

Immediately afterwards, the person in charge showed Xia Zhi the artificial skin called ICX-SKN developed by Intercytex Group, which is engaged in cell therapy research.

ICX-SKN is composed of connective tissue cells, a matrix produced by autologous skin cells.

Connective tissue cells form collagen in natural skin.These connective tissue cells form a tissue structure similar to real skin.

This skin can fully integrate with the human body after 28 days, sealing and healing wounds.In preliminary clinical trials, artificial skin grafts have achieved breakthrough success due to their realistic texture and good durability.

There's also a new type of artificial skin developed by NASA scientists: carbon nanotubes.

Vertical carbon nanotube layers are arranged on the rubbery polymer used in plastic surgery, just like implanting a piece of skin, and the carbon nanotubes are held together by strings of gold wires.

These carbon nanotubes are distributed on a rubber-like polymer, and the artificial skin combining rubber polymer and carbon nanotubes can transfer heat from the contact surface to the sensor network, just as the skin can pick up this information in time.

After the carbon nanotubes enhanced piezoelectric sensing on the polymer, the sensor was able to generate a signal to the robot's brain.

Vladimir Rumelsky, a technologist at NASA's Goddard Space Flight Center, implanted sensors into the robot's skin covering. This high-tech robot skin can make robots better at space exploration missions. Unlike the "physical condition" of robots, in order to realize the intelligence of robots, robots also need sensitive skin to produce a certain sense of touch.

A robotic skin capable of producing pressure and temperature sensations has been developed. This artificial skin can detect various things simultaneously with human skin.

Transistors used in circuits and semiconductors become "skin organ materials" based on chains of carbon atoms so that robots can have a human-like sense of touch.

The last kind of artificial skin is half out of the medical field. It is a cooperation project between the technicians here and the robot project team.

At the last leadership meeting, some leaders suggested that Zhixia Technology could develop robots in the next stage.

At that time, Xia Zhi did not deny it, but asked everyone to submit application materials, and then after the approval of Zhixia Technology, they could get the first phase of research funding.

If you can research something that interests Xia Zhi, you can continue to submit application materials to Xia Zhi.

So Zhixia Technology can do everything internally now.

There are not only robots, but also artificial intelligence, and even Gundam fighters.

When the Institute of Biological Sciences of Zhixia University of Science and Technology was booming, the battery pack of the School of Physics next door also made great progress.

It has been more than a month since Ye Lihai's accident last time. During this period, the researchers in the battery pack did not slow down their research progress.

While raising safety awareness, they pushed forward project development, and finally helped Xia Zhi figure out the system task of battery technology in his mind.

On this day, the members of the battery pack were still discussing how to solve the overheating problem. Xia Zhi walked into the research room and said with a smile:

"I got a piece of top-secret information about a new type of battery, take a look."

Said, put a document on the table.

The person in charge of the battery pack took it over and looked it over, his expression slowly changed, he asked Xia Zhi in surprise:

"Mr. Xia, where did this information come from? The technology on it has completely refreshed my understanding."

"Is it so fierce?"

The members next to him couldn't help being curious and leaned over to take a look.
