Technology: The naughty kid ruined my college entrance examination, but I turned over to nuclear fus

"Three yes?"

"Okay, let's try it first!"

Several researchers said with a serious look.

According to Lu Yu's instructions, they began to prepare in the laboratory, and soon, several graphene neuronal transmitters that met Lu Yu's requirements were quickly made!

"Let's try, three neuronal graphene sensors, two placed in..."

"Zizi..."

With a burst of electric sound, the graphene sensor was completely installed! And some exoskeleton equipment has also begun to operate!

"How, how's it going?"

Lu Yu asked.

"So far, everything is in line with our expectations and there are no signs of failure."

"It should work!"

The researcher in charge of observing the data said with a look of excitement!

It is indeed a pleasure to be able to directly confirm the number and position of the appropriate neuron in such a short time! Seeing that his calculation was successful, the corner of Lu Yu's mouth slowly hooked a smile:

"Okay, since there is no problem, then it is so decided!"

"Our neuronal transmitters are placed in these two positions, and the number remains at three, unchanged."

"Next, there are nano-metal active electrodes, as well as the installation of multi-walled carbon nanotube active batteries, to solve these two problems, our research work, can temporarily come to an end."

"No, it's not appropriate to say it's an end."

"It should be said that I don't need to be so busy for the time being."

Lu Yu said with a smile.

If they can solve these two problems tonight, there is no doubt... Follow-up research tasks will be much lighter in an instant!

Next, you only need to base the data of the exoskeleton device! There is no need to do other innovative work, and their research tasks are naturally much less!

The premise is .... When it comes to landing tests, don't be surprised!

"Tell the truth."

"Graphene neuron sensors are simple to solve, but the installation location of the remaining two is really troublesome."

"yes, it's tricky."

Thinking of the next two tasks to be solved, the researchers' faces showed a complicated color. Although their first task tonight was solved very smoothly, it can be said that it was solved with almost no effort!

However, the next two tasks to be carried out are not ordinary troubles to be solved!

If a single task is compared to 1 in a number, then the difficulty of the three tasks added up is far from as simple as 1+1+1=3!

When installing neuronal graphene transmitters, you only need to simply consider the number and location of installations!

However, if you want to install nanometal active electrodes and multi-walled carbon nanotube active cells at the same time, you need to consider compatibility and safety at the same time!

With each installation of the previous section, the difficulty of the next task will be increased by a geometric multiplier!

"The next task may be a bit of a hassle."

"But don't panic, after the complex task is broken down into simple parts, it will not be much difficult to solve."

"Let's start with the first step."

Lu Yu smiled.

"Who's going to talk about their thoughts first?"

He looked around and rested his gaze on everyone's faces.

"I'll come first!"

A middle-aged scholar from the Dragon Kingdom slowly stood up and said, "

Our first installation task should be the nano-metal active electrode."

"In terms of use, this instrument is used to convert bioelectric signals into mechanical power signals, so the number of their installations should be determined by the movement and degrees of freedom of the exoskeleton equipment controlled by need!"

"If you only want to control the simple movements of the exoskeleton device, such as walking or jumping, you may only need to install some electrodes on the joints or muscles" "But our goal is to make the exoskeleton device more flexible, that is, we want to control the complex movements of the exoskeleton device, such as climbing or fighting..."

"

Then we may need to install

more electrodes in different positions, various joint parts, It may be necessary to have the right number of active electrodes.

With

some explanation, the middle-aged scholar slowly expressed his point of view.

"I think we have to prepare at least twelve active electrodes and place them in batches!"

"Twelve?"

Hearing this amount, everyone's eyes showed a hint of hesitation: "Will this amount be a little too much?"

"Each active electrode is controlled by an independent unit!"

"If twelve active electrodes are installed at the same time and placed on different joints, if the signal is disordered, the interference is unimaginable!"

Another Dragon Kingdom scholar slowly stood up and shook his head,

"I don't think that twelve active electrodes of this number are too much. With the bearing capacity of our exoskeleton devices, twelve should be completely bearable.

"But..." Listening

to everyone's explanation, Lu Yu was a little out of his mind.

"Actually, it comes down to it."

"The most important thing to consider in the installation of nanometal active electrodes is actually its matching with neuronal transmitters, you should be able to understand what I mean, right?"

After thinking for a while, Lu Yu finally spoke:

"That is to say, the most important thing is that the nanometal active electrode needs to match the graphene neuron sensor!"

"Only in this way can they be guaranteed to receive and process the signals output by the sensor without interfering with or impairing the sensor's functionality."

"Our task is to adjust their resistance, capacitance or inductance to suit the output characteristics of the sensor."

"In other words, as long as we can ensure the right inductance parameters, the more neurons, the better."

"Do you agree with me?"

Seeing that Chief Engineer Lu spoke, everyone's eyes suddenly turned to Lu Yu, and after listening to his speech, everyone showed a complex color.

"That's a good thing to say."

"If

there are too many of them, our inductor parameters and capacitance are a little too difficult to control, right?"

Many people have some hesitation on their faces.

Why don't they understand the meaning of Lu language?

The more active electrodes, the more detailed the manipulation of neuronal sensors. If you can make the operation of each joint to the point of doing whatever you want, you will definitely be able to make the neuronal sensor more sensitive.

But the problem is, the ideal is beautiful, but the reality is somewhat cruel!

The greater the number of nanometal active electrodes, the greater the signal interference will be generated, and the difficulty of properly controlling capacitors and resistors is a geometric multiple!

Therefore, some people have hesitation on their faces.

"Then Chief Engineer Lu, what do you think is the appropriate number of our nanometal active electrodes?"

A scholar asked slowly.

"20."

Lu Yu said a number with an indifferent face.

"How much?"

Several researchers showed a look of disbelief on their faces, and even Su Xiaoxiao looked at Lu Yu with a puzzled look as if he had misheard.

"Twenty."

Lu Yu looked calm and repeated it directly.

"What twenty, this... How can this be controlled? Everyone

was stunned!

At the beginning, when the middle-aged scholar said twelve neuron sensors, they all thought that this number might be a bit too much, but who knew that Lu Yu directly wanted to arrange twenty at the same time at the beginning!

That's too risky, right?

"I know."

"If twenty nanometal active electrodes are connected at the same time, it will have certain requirements for our control ability."

"But there are difficulties, we can overcome them! Don't be too nervous!

Lu Yu said slowly.

In the final analysis, the control of capacitance and resistance is still in the problem of efficiency!

Only need to lift the efficiency of the active electrode, then let alone twelve active electrodes, is to access twelve electrodes, there is no problem at all!

This is exactly the question that Lu Yu was thinking about just now!

"We need to have efficient energy conversion and utilization capabilities, only in this way can we guarantee that they can convert bioelectric signals into enough mechanical power signals without wasting or overloading energy!"

"The number of twenty active electrodes, at first hearing, may be exaggerated. But as long as their installation structure and materials can be optimized, their power density and energy density can be improved.

"It is not impossible to arrange twenty nanometals at the same time!"

Lu Yu slowly stated his point of view, and the faces of the scholars present showed a trace of doubt.

"Chief Engineer Lu, do you mean to let us increase the power density and energy density, and then optimize the installation structure of nanometals?"

"But... In such a short time, it is probably a little difficult to do this in one go.

A Germanic scholar raised his hand and asked.

In fact, everyone understands the principle of Lu Yu's idea, but the difficulty is not in this principle, but in the specific operation!

Let's use an analogy.

This question is like asking a person how to get into a top-2 university.

The answer, of course, is to study hard and improve every day. But the question is how to study how to be admitted to the top 2 universities, and how hard do you have to work to get it?

These are all question marks!

"The difficulty is real, I don't deny it."

"However, we are focusing on the experts in the relevant aspects of the entire Dragon Kingdom here, don't be modest, we are all united and will definitely be able to complete the task."

"Next, let me explain to you my specific thoughts."

Lu Yu said with a smile.

Of course he knew what everyone was worried about. However, with the knowledge of exoskeleton equipment given by the previous system, coupled with the deep understanding of this project in his mind, Lu Yu has roughly figured out some of the key points!

"First of all, if we want to ensure stability."

"The first step is to add a filter that allows it to control the resistance function of the active electrode more stably."

"Only in this way, under the premise of twenty active electrodes, can it also maintain its stability."

Lu Yu took the lead.

Filter?

Everyone thought about it, and they all nodded.

Many of them, when considering this problem, also consider the filter device in their range.

A filter is a circuit that removes unwanted components from a signal and retains the required components.

The principle is to use the characteristics of components such as capacitors, inductors and resistors to select the frequency of the signal, so that the signal in a certain frequency band can pass through, and prevent or attenuate the signal outside other frequency bands.

"In fact, in addition to the filter, it can also be achieved by reducing the gain, but the reason why we chose to install so many active electrodes is to improve sensitivity, and reducing the gain is counterproductive."

Lu continued:

"So, our goal is simple, find a suitable filter, and then get the parameters to a suitable value!"

"Yes, Chief Engineer Lu!"

Everyone nodded and began to think about which filter was more appropriate!

There are several types of filters, which can be divided into low-pass, high-pass, band-pass, and band-stop filters depending on the frequency range they pass.

Adding a filter between the electrode and the exoskeleton device will inevitably remove external interference or interference between electrodes, and improve the purity and stability of the signal!

It's not hard to think of this.

How to use the filter reasonably, and how to control the specific parameters to achieve a stable goal, this difficulty is not ordinarily high!

"If we want to preserve the signal in one band and remove interference or noise from other bands, we should use a band-pass filter!"

"But the band-pass filter can only target a certain section of a special signal, for other signals, the recognition ability is too weak!"

"I still think it's more appropriate to use a band-stop filter!"

"Yes, a band-stop filter suppresses signals in a certain frequency band and allows signals outside that band to pass through! This is more suitable for us to fend off the information warfare offensive of the other side!

After

a heated discussion, the researchers reached a consensus!

Use a low-pass filter, not a band-stop filter!

The next step is to decide the parameters!

Lu Yu's eyes narrowed slightly, and he quickly analyzed!

"The cutoff frequency of the low-pass filter is fc=1/(2πRC), which indicates that the signal pass rate below this frequency is 70.7%, and the signal pass rate above this frequency gradually decreases."

"In order for the low-pass filter to effectively filter out high-frequency interference, we need to keep the cutoff frequency as low as possible, which means we need to make resistor R and capacitor C as large as possible!"

"However, the magnitude of resistor R and capacitor C cannot be increased indefinitely, as they affect the working efficiency and stability of the active electrode."

"Too much resistance R will cause the operating voltage of the active electrode to decrease, which will affect its ability to store energy and release energy; Excessive capacitance C will prolong the charging and discharging time of the active electrode, thereby affecting its response speed and life...."

Everyone was silent, looking at Lu Yu!

"He won't... Do you want to calculate the result directly? "

A bold idea that rises in everyone's mind!

The next moment, Lu Yu suddenly opened his eyes!
