The so-called chip implantation is by no means what most people think is to implant the traditional chip into the human body, which will cause serious rejection, and naturally cannot be applied to the bionic human using biotechnology, it can only be an intelligent machine, and the intelligent robot cannot achieve the confidential effect that Luo Sheng wants.

Another reason is that even if the traditional chip can be compatible with the application, it also means that a battery must be installed in the bionic body to power the chip, which is very power-consuming, and it is obviously a clumsy design that Luo Sheng cannot accept.

Only chips made of biotransistors can solve the problem of compatibility with living organisms.

You must know that although bioelectricity and the electricity used in people's electronic devices in daily life both have the word "electricity", the two are not the same thing, and there is a great difference in nature.

If it is necessary to convert the bioelectric signals generated by living organisms into electronic signals that control machines without distortion, no one has done it yet, at least until Luo Sheng is completely involved, no one in the world has done so.

And if this is not achieved, even if a powerful chip core is installed in the android's body, it will never be as sensitive as a real organ.

In the days that followed, Luo Sheng alone and with the assistance of Cortana, he began to work hard to overcome this technical problem, which required him to master and master the knowledge of multiple disciplines at the same time.

The principles are not difficult to understand, and even contain basic physics knowledge at the secondary school level.

The movement of the charge forms an electric current, the so-called "carrier", which can be positive or negative, and the current used in all electronic devices at present, the carrier is electron, which carries a negative charge.

But the difference is that the so-called bioelectricity in organic life is very different in this regard, there are some special channels on the cell membrane of organisms, when the ion concentration inside and outside the cell membrane is out of balance, these channels will open, and sodium, potassium, calcium and other ions are released from the cell or flow in from the outside of the cell, thus forming bioelectricity.

It is based on this that people can control their bodies, and if they do not swim with these ions, they cannot raise their hands and kick their legs, or even see the outside world, because electrical signals are conducted from the retina to the nerve center of the brain, relying on a set of mechanisms that want to be the same.

Bioelectricity is produced by the swimming of ions, which carry a positive charge.

In other words, the electronic devices made by humans and the carriers of electric current in the human body are not the same particles at all, and it is quite simple to achieve perfect interaction between living organisms and electronic devices, either by "translating" bioelectric signals into electronic signals, or by "translating" electronic signals into bioelectric signals.

It is said that it is simple, but it is not possible for anyone to achieve it, and it is necessary to take into account that many rich details are lost in the "translation" process, which can cause signal distortion.

……

The seventeenth day of the retreat.

In the laboratory, Luo Sheng is still silently researching, and several display panels are full of papers related to his research, which are all papers published by other scholars in the industry, and Luo Sheng must of course use them for reference research.

Cortana's voice suddenly resounded in the quiet laboratory: "Master, today is the sixteenth consecutive day that you have worked more than 15 hours a day, and your physical data shows that your brain is now in a state of overfatigue, and you really need to rest." ”

Luo Sheng slid one of the display panels, stared at the paper analysis on it, and said lightly: "Didn't I tell you that I didn't monitor my physical condition if it's okay, you have to help me, not block me, you know?" ”

Cortana replied, "Okay then..."

During this time, Luo Sheng was not only overcoming technical problems, but also unconsciously mastering three new knowledge in order to overcome the problems, and all of them have reached the point of mastery, which is the best interpretation of Yitong Baitong.

In Luo Sheng's design idea, the ideal machine that deals with biological cells needs to have two basic conditions: first, it can be compatible with organic life and will not be rejected; The second is to communicate with the cell in its own 'language'.

In other words, the best way to transmit an electrical signal is to carry a positively charged particle, which controls the movement of positive ions in and out of the cell membrane.

This line of thinking leads directly to the biotransistor.

In daily life, the soul of common electronic devices is the transistor, which is also the basic element of the chip, and the transistor is essentially an electronic switch that controls the current, and an external electric field can be applied to it to determine whether it is turned on or off.

When human beings first invented the transistor, a transistor was as long as 1 centimeter, and with the progress of science and technology and the rapid development of integrated circuit industry technology, a chip the size of a fingernail can now accommodate tens of billions of transistors.

Over the next few days, Luo Sheng spent his days in the lab making a small part that could function as a transistor, but instead of controlling electrons, it controlled positively charged ions.

In addition to this, it also has to be compatible with living organisms, which is the so-called biotransistor.

Like biologists who have been working for decades to develop biological transistors, Luo Sheng uses sodium, potassium and calcium ions to pump into the cell's ion pump, but unfortunately the materials used are not compatible with living organisms.

In the following week, Luo Sheng tried a variety of methods, but the test ended in failure.

……

In the blink of an eye, the time has come to June.

At this moment, it was dinner time, and there was a whole table of sumptuous dishes on the table, and there were four people at the table, namely Luo Sheng, Qin Weimu, Erin and An Qingxue.

It is a rare famous scene.

Strictly speaking, counting the little princess in An Qingxue's arms, it is considered five people.

There is a delicious taste made of freshly caught Yangcheng Lake hairy crabs on the table, but this is not suitable for An Qingxue during pregnancy.

At this time, An Qingxue suddenly looked at Luo Sheng and said, "Brother Luo, can you promise me one thing?" ”

"What's the matter?"

Luo Sheng replied casually, he was multitasking while dining, thinking about the matter of biological transistors, and he was a little depressed by this question recently.

"From tomorrow the working hours will be halved, and the eight-hour work day will be resumed, even if you don't think about your body, you have to consider our feelings, and the daughter who is about to be born."

Hearing this, Luo Sheng couldn't help but be stunned, and immediately looked up at Qingxue Mei's paper, and then turned his head to look at Erin and Qin Weimu, the two of them didn't say a word as if they had nothing to do with themselves, but when their eyes met with their eyes, they saw a taste of resentment caused by being left out.

Luo Sheng realized that he had spent almost all his energy on technical research during this time, and he really only cared about research, and when he thought of this, he immediately nodded and smiled: "Okay, I promise you." ”

But at this moment, when Luo Sheng looked at the plate of hairy crabs on the table, he suddenly had an epiphany at that moment.

"I think I've found a solution...... Eat it, I've got to go to the lab first. Luo Sheng suddenly got up from the table quite excitedly, said a word and went to the laboratory, pretending not to see Qin Weimu and Erin's resentful eyes.

It took a second to say yes......

After a while, Qin Weimu said lightly: "It's not only men who can solve the problem of demand with their own hands, women can too, Xiao Ai will play together later." ”

An Qingxue: "??? ”

Xiao Ai: "??? ”

The two faces were stunned for a moment.

What a wolf's words......

On the other side, before Luo Sheng went to the laboratory in District 32 on the ground floor, he went to the kitchen and brought a bag of fresh hairy crabs to the laboratory.

It was when he saw those crabs on the dining table that Luo Sheng suddenly realized that chitin fibers can be extracted from crab shells, and chitin fibers are the only positively charged polymer materials in nature.

Isn't this the best material for the biotransistor you want to make?

That night, Luo Sheng was alone in the laboratory to refine the polymer material in the carapace of hairy crabs and make nanofiber tubes composed of this material, which can allow protons to flow.

Applying an external electric field to it can also determine whether proton flow accelerates or stops, and the material is soft and tough, making it compatible with biological organisms.

By three o'clock in the morning, in the lab, Cortana's voice responded with joyful emotion.

"Congratulations, master, you have finally built the world's first biotransistor."

Luo Sheng couldn't help but smile and said: "Finally found a solution, this step is easy to step underneath, everything can fall into place." ”

I didn't expect that in the end, it was up to crabs to solve the problem.

However, there are still many problems before the real manufacturing of usable biochips, and the next step is to solve the integration problems of chips and the design of biochips, which are no different from traditional chips, and the existing chip design, manufacturing and other related technologies can provide technical support.

Luo Sheng couldn't help yawning, and after overcoming the problem, fatigue hit instantly, and he stretched and left the laboratory.

I can finally rest for a while.
