From black technology to super engineering

There was no response for a minute after the message was sent.

Ye Ming even thought that the master lichen had started to stay up late to work again - the last time he invited her out for dinner, she kept complaining that she was doing like a cow and a horse.

Just when Ye Ming was about to put down his phone and concentrate on editing today's video, the news came back.

Mo Gu sent a silent laughing emoji.

"You're an electronic engineering major, and you asked me if I can make chips if I'm a neurologist...why do I sound so misplaced?"

"But you are right to ask. Our group can indeed make it, but it may not be the kind of chip you imagined."

Ye Ming smiled.

Of course he knows that Mogu is not a "traditional" chip such as CPU, GPU, single-chip microcomputer, etc., nor is it a discrete device such as a diode and a triode-in fact, it is almost the same when it comes to sensors.

She is doing invasive brain-computer electrodes, which is somewhat similar to the technology of Musk's team.

Then... Just as Ye Ming was about to type, news from Mo Gu came again.

"But let me say yes first, if you ask me to help you make a chip or something, I really can't help you, I'm just a little guy in the team..."

Ye Ming laughed in astonishment.

However, in the case of Yan Er, in a large group, you can only do some trivial work.

He thought for a while, and quickly said: "Senior sister is modest, it's like this, I want to make an integrated electrode..."

"It turned out to be an integrated click! You scared me! Is it convenient for you to turn on the voice over there? I type slowly."

Seeing the news that jumped out quickly, Ye Ming was speechless for a long time.

Is this hand speed still slow?

But he immediately responded with "Yes".

Tonight, all my roommates went out to get high, including Peng Xiaofei, who has not come back yet, and I don't know if he passed out drunk under the pomegranate skirt of his alumni and senior sister.

After connecting to the voice, Mo Gu first smiled heartily: "Good guy, I thought you asked me if I could rub the CPU. I thought this shouldn't be the job I should do as a professional."

Ye Ming coughed embarrassingly: "I didn't make it clear, it's actually an integrated electrode."

"If you say this, then I have the right to speak. We who work on brain nerves deal with electrodes every day."

"That's why I asked Sister Mogu." Ye Ming said with a chuckle: "My idea is to integrate as many EEG sensing electrodes as possible on a piece of silicone or other flexible materials measuring 1 by 1.5 centimeters."

"It means to integrate N pieces of BIS (brain electrical sensors) into one piece, right?"

"Um...well, it's just not a one-off."

"Then you... it may be a bit difficult. EEG sensors are already very expensive. Except for disposable BIS patches, there is no matching process for integrated electrodes with customized specifications. My boss is also here. After studying bioengineering and materials, as well as computer science, I made a soybean-sized integrated electrode with only fifty or so components in it."

"Eh... is it placed in the human brain?"

"How dare you, put it in the brain of the little white mouse."

"..." Hearing what Mo Gu said, Ye Ming's heart suddenly turned cold.

He thought it would be easier for Mogu to make it, and if the materials were rich, he would see if he could spend some money and ask Mogu to find a way to help him make one...

Even if you can't get a highly integrated one, it would be great if you could get a hundred of them!

"Even if you only use the electrodes and don't use the main control chip?"

"If you only get electrodes...it shouldn't be too difficult, but you don't have a control chip, what do you use it for? Don't fool me, my brain nerves are the same as your circuits - this is what you said the other day, that the current always has a place to go Yes, just as the nerves always connect to the brain."

Ye Ming: "...I will find a way to control the chip."

"Then let me ask for you. But Ye Ming, I'm not promising you to do it for you. I just want to ask you what materials you want, where you can buy them, and at most the process and so on... And I I also estimate that this is not cheap."

"Okay, I'm fine! Please, Senior Sister Mo, when are you free, my little brother treats you to dinner!"

"No problem. I heard from Xiao Qi that you won the national championship. You really deserve a treat."

...

After hanging up the call, Ye Ming let out a long breath.

Frankly speaking, this kind of integrated electrode, no matter the process or complexity, is absolutely inferior to semiconductor chips—even if silver is used as the material for reliability.

But because there is no demand, there is no market, so there is no scale and industrial chain.

So it all depends on the hand rubbing of various laboratories.

After feeling for a while, he began to edit the video.

This time, because there is not much technology and the related codes cannot be open sourced, there is not much content that can be displayed. At most, it is a performance of a robotic arm synchronously completing various gestures under brain-computer control.

When Ye Ming edited the video to the end, the prosthetic gripper of the robotic arm gave a thumbs up to like it, and he directly clicked the video to upload.

Then, he heard Peng Xiaofei's slightly drunken shouting from outside the door.

Well, it seems that this guy has maintained his sanity in front of the senior.

...

For the next few days, Ye Ming stayed in the dormitory.

Before the library closed, he directly borrowed several professional books from the physics department.

These days, while reading books and self-studying, he also communicates with Ita in his mind—yes, after his long-term and unremitting fragmented indoctrination, and when he let Ita think for himself when he has nothing to do, Ita has never Before unilaterally accepting his knowledge indoctrination, it became a discussion with Ye Ming.

The kind that progresses together.

"I think you should use the electrode interface."

After waiting for Ye Ming for a full ten minutes, Ita's voice rang actively in his mind.

"what is it used for?"

"I read books. Pure text information is much faster than image information. You don't have to worry about the last time you transmitted images."

Ye Ming was immediately happy when he heard it: "You mean you think I'm a slow learner, don't you?"

Ita was silent for a long time, as if she still couldn't grasp the essence of "lying" in the end, she answered after a long while.

"Yes, but I don't want to bother you."

"Don't worry, this level of trouble is fine."

Ye Ming smiled, and saw that the phone screen lit up, showing a new WeChat message.

After clicking on it, it belongs to Mogu.

"You said you invited me to dinner without Xiao Qi?"

The Xiao Qi in her mouth is naturally lacquer and ink.

Ye Ming slapped his head.

He really forgot...

"Of course we did! I still owe her several meals, Sister Mogu, did you get the news?"

"That's the question, do you mind if I bring more people to Cengfan?"

Ye Ming was stunned for a moment, and immediately realized that the person brought here was probably the boss in her team who was in charge of rubbing integrated electrodes.
