Chapter 462
Looking at Liu Miaoer.
Ye Qiaoqiao blinked his eyes and said with a smile:
“Miao’er, I thought of a possibility!”
“You said that person, could it be…” ”
Your father?”
Liu Miaoer: “??? Hearing
Ye Qiaoqiao’s blurted out thoughts, Liu Miaoer was directly stunned, and her expression was also frozen.
“What
did you say?”
“My dad?”
Liu Miao’er looked at Ye Qiaoqiao with a confused expression, and asked suspiciously: “Your brain… Why are brain circuits so jumpy? What does this have to do with my dad?
“No, Miao’er.”
“You want to!”
Ye Qiaoqiao said with a smile:
“The person who helped you a lot did not come forward directly, nor did he let Director Zhang tell you his identity, doesn’t this mean… Doesn’t he want you to know who he is?
“Generally, isn’t this image all that kind of old father?”
“And if I’m not mistaken, your family’s family foundation is quite thick, do you say that your father helped you in secret, and then didn’t want you to know, so let Director Zhang not tell you about this?”
Ye Qiaoqiao roughly told Liu Miao’er the guess in his heart, and the latter’s expression suddenly became very strange.
It’s an expression that doesn’t know whether to laugh or not, between being tense and not being able to hold back.
“Qiaoqiao, what are you thinking?”
“Where does my dad have this strength?”
“Our family’s family foundation is indeed okay, but at most it can only be regarded as okay, where can his little circle of contacts reach Director Zhang?”
“It absolutely can’t be him!”
Liu Miaoer cried and laughed, and shook her head.
Their family is indeed rich in Luohai City, their father is the boss of a company, their mother is the director of a third-class hospital, and the family also has several small goals.
It is indeed a person with a relatively thick family foundation.
But…. With her parents’ connections, she wants to influence the casting of director Zhang… Obviously, foolish dreams!
Don’t talk about the gold lords behind those A-list actresses!
Let’s just say that those actresses themselves, which one is not worth more than their entire family base? And in the entertainment industry, the connections and “professional” are more matched, and even they can’t get that role by relying on the operation of their own relationships, let alone themselves!
Therefore, Ye Qiaoqiao’s guess can be said to be 100% unreliable!
“That’s not your dad, who will it be?”
“A person who doesn’t want your attention has done you so much in secret, and he is not willing to show up.” This is simply the plot of an idol drama!
“When will this kind of good happen to me once?”
Ye Qiaoqiao hugged the pillow and rolled up and down.
Her words, although unintentional. But the speaker has no intention, the listener has intention. After listening to these words, Liu Miaoer suddenly thought of something, and her eyes showed a different color.
“Is it…. It’s him? I
don’t know what’s going on, Lu Yu’s handsome face came to her mind.
“It shouldn’t be.”
“If he really helped me, I really wouldn’t want me to know.”
“But how can he affect Director Zhang’s casting?”
Liu Miaoer yawned, shrunk into the quilt, and thought secretly…. Suddenly, a string of memories came to her mind!
“Is
it because of virtual reality?!”
Liu Miaoer’s eyes suddenly lit up!
She also remembers when chatting with Lu Yu some time ago, when Lu Yu talked about virtual reality technology, he blurted out a sentence about our institute.
Although, at that time, Lu Yu quickly explained that it was because of his own slip of the tongue and said it wrong.
But this matter was firmly remembered by Liu Miaoer!
If the enhanced virtual reality technology used in “Dragon Kingdom Myth” is really researched by Lu Yu, then everything can make sense in an instant!
As a supplier of technology, if Lu Yu wants to find a relationship, let Director Zhang divide the role to himself.
Presumably, Director Zhang will definitely not refuse!
After all, the county official is better than the current management! The technology is all people’s, people assign a role, what else can you say?
“Is it really him?”
“No, when he comes back, I must ask him well!”
Liu Miao’er glanced at the starlight outside the window, clenched her small fists, and secretly thought in her heart.
The time —
night in
the ancient camel mountain
soon passed.
As the rising sun rose, Lu Yu slowly opened his eyes, got up and walked into the conference room.
Today is the day the landing test begins!
They still have three to five days to complete the new technology they talked about before, and then five days later, the exoskeleton device is officially put into the ancient camel mountain, out of the perfect experimental environment, and officially complete the tasks set before!
There is no doubt that the workload of these two days will be terrifying!
Walked into the conference room….
“You came so early?”
“I’m still thinking about coming in first and arranging some things in advance.”
Lu Yu took some printed materials, and as soon as he entered the conference room, he caught a glimpse of Su Xiaoxiao, who was already sitting inside.
“yes.”
“I just guessed that you would definitely come to the conference room early, so I came here earlier to help you get some work.”
Su Xiaoxiao said.
She naturally stood up, took the documents from Lu Yu’s hand, and then distributed them in batches to each seat on the table.
“Why, why are you looking at me with such strange eyes?”
Su Xiaoxiao glanced at Lu Yu strangely and asked.
“I
just didn’t think that you would..” So intimate?
Lu Yu scratched his head and replied.
“After all, this idea was proposed by me, but you need to complete the practice concretely, and I should help you do more miscellaneous work.”
Su Xiaoxiao said casually.
“Okay.”
“At that moment, I have to trouble you to give them a preliminary introduction.”
“I have to test one of my conjectures first, I don’t know if I can come back in time.”
Lu Yu glanced at Su Xiaoxiao gratefully and said.
“Okay, then leave it to me first, you go and take care of yours.”
Su Xiaoxiao returned an “OK” gesture.
Seeing Su Xiaoxiao’s reaction, Lu Yu’s heart was suddenly much more relieved, and he directly handed over all the materials to Su Xiaoxiao for distribution, and then walked all the way into the laboratory.
Although I couldn’t get in yesterday.
But in his bedroom, he had a lot of interesting ideas, some of which Lu Yu couldn’t wait to start verifying!
Once verified!
When you share it with the group members, the progress can also be accelerated!
“Squeak…” Lu
Yu directly pushed open the door of the laboratory and walked in!
“Now, let’s solve the first and most important problem.”
Lu Yu took a deep breath, his eyes showed a dignified color, and quickly began to operate according to the ideas in his mind yesterday!
You want to connect neuronal transmitters into exoskeleton devices.
The first inescapable problem is how to connect neuronal transmitters with actuators of exoskeleton equipment (hydraulic, motor, pneumatic, etc.) to achieve precise force feedback and coordinated motion control!
If precise force feedback and coordinated motion control cannot be achieved.
Inserting neurons into it may not only not improve the reaction speed of the exoskeleton armor, but also lead to a significant decline in the accuracy of the armor’s control, and the gain is not worth the loss!
So, this problem must be solved!
According to Su Xiaoxiao’s idea, in order to connect neuronal transmitters with actuators of exoskeleton devices, their team can use biomimetic technology to design a flexible material similar to muscles as a power source for exoskeletons.
This material can receive electrical signals from the brain through neuronal transmitters, resulting in contraction and relaxation movements, ensuring the precise operation of the exoskeleton armor…
And Lu Yu came to the laboratory this time to verify whether it is feasible to solve the problem by making flexible materials!
The concept of flexible materials is not complicated, it refers to materials that are highly bendable, stretchable, twistable and can mimic the flexibility and adaptability of biological tissues. For example, polyester fabric, high-chemical silicone, etc…..
In fact, there are precedents for using flexible materials to make exoskeleton devices.
It uses flexible materials as the transmission unit of auxiliary force, and can perform single-joint or multi-joint synergistic assistance on human lower limbs. For example, Soft Exosuit at Harvard University and Myosuit at ETH Zurich.
However, in previous precedents, most exoskeleton robots made of flexible materials were used for recuperation, or purely experimental products. Used in combat-shaped exoskeleton equipment vendors, it has never been done before!
Therefore, Lu Yu’s attempt this time is undoubtedly very bold!
“Let’s give it a try according to my ideas yesterday.”
Lu Yu also has no ink, just do it.
Combined with yesterday’s discussion with Su Xiaoxiao and some of his own ideas, in the end, Lu Yu chose to use polyvinyl alcohol as a raw material for flexible material processing!
The reason why it was chosen as a processing forgiveness for flexible materials, Lu Yu naturally has its considerations.
First of all, polyvinyl alcohol is a water-soluble polymer, which can be made into a film by simple solution casting method, or it can be compounded with other materials by in-situ crystallization method to form a flexible polymer film with special properties.
The length and cost of the production process are not high.
Secondly!
Polyvinyl alcohol also has good film-forming, lightfastness, mineral oil and grease resistance, and can be used as a protective or decorative layer for flexible exoskeletons, improving its appearance and durability!
Most importantly, it has a high degree of gas barrier, stretch resistance and moisture absorption, can be used as a functional layer or structural layer of flexible exoskeleton, improve its air tightness and strength, some advantages at the same time, it is also non-toxic, non-irritating to human skin, biodegradable and other environmental protection characteristics, can be used as a safety layer or comfort layer of flexible exoskeleton, improve its affinity and sustainability.
After combining many ideas, Lu Yu judged that polyvinyl alcohol is the most suitable flexible material!
After thinking about it.
“I’ll have to use you.”
“Without your specific processing tools, just thinking about it with your brain, it will still be a little troublesome after all.”
Lu Yu slowly turned his head and set his sights on the laser cutter and ultrasonic welding machine in the laboratory. These two experimental tools are the main processing tools of polyvinyl alcohol flexible materials this time!
It is difficult for a clever woman to cook without rice….
If he couldn’t get into the laboratory, without these tools, he really couldn’t get started.
He first cast the polyvinyl alcohol solution into a film, and then put the film on the workbench of the laser cutting machine, set the power, speed and path of the laser according to the size and shape of the need, and then began to start the laser cutting machine to let the laser cut the polyvinyl alcohol film along the set path.
“Moisturize!”
With the roar of the machine, the first step, cutting the polyvinyl alcohol film is done!
Lu Yu stacked two polyvinyl alcohol films on top of each other, and then placed the stacked films on the workbench of the ultrasonic welding machine.
After roughly judging, he quickly set the frequency, pressure and time of the ultrasonic wave according to the welding position and strength according to the needs! Immediately after, press the start button!
Ultrasonic waves generate heat through pressure and vibration, which quickly fuses two polyvinyl alcohol films together at the point of contact.
“Whew…”
“Done.”
“Then comes the final step.”
Seeing that the polyvinyl alcohol film was smoothly welded together, Lu Yu breathed a sigh of relief and began the final processing operation.
This time, he plans to print polyvinyl alcohol with an inkjet 3D printer!
Lu Yu first loaded the polyvinyl alcohol solution into the ink cartridge of the inkjet printer, and then put the substrate that needed to be printed on the workbench of the inkjet printer!
“Color… Just black. He
set the colors and quickly adjusted the resolution, speed, and orientation of an inkjet printer! Let the data be balanced!
Then, Lu Yu starts the inkjet printer!
“Buzz…” was
accompanied by a noise of the machine starting.
The inkjet printer begins to spray the polyvinyl alcohol solution onto the substrate in tiny droplets through the nozzle, forming the initial prototype of the desired flexible material!
After the prototype is completed.
The next thing to do is to further process!
Lu Yu’s idea is very simple, choose to use the simplest processing method, that is, in situ crystallization method to process polyvinyl alcohol!
He mixes small molecule ferroelectric materials with spontaneous polarization ability with polyvinyl alcohol solution homogeneously.
This time, the small molecule ferroelectric material he chose was polyvinylidene fluoride, and the content was set at about 14%.
Generally speaking, the higher the content, the better the dielectric properties of the composite film, but the easier it is to affect the film-forming properties of polyvinyl alcohol.
Therefore, Lu Yu still chose the “golden mean” to control the content in the range of 14%-15%.
Immediately afterwards, he used the solution salivation method to cast the mixed solution on the glass plate, and in order to make the composite film flexible enough without cracking, he carefully controlled the thickness to 45 microns.
Then put the glass plate into a vacuum drying oven, adjust the temperature to 120 degrees, and catalytic drying and crystallization are carried out through the device, so that the small molecule ferroelectric material is covalently combined with polyvinyl alcohol molecules!
Forming a transparent flexible polymer film with a high dielectric constant!
“Whew, the last step.”
Lu Yu carefully peeled off the composite film from the glass plate and began to polarize under a certain polarization electric field and time.
Generally, between 100kV/cm~300kV/cm, the longer the time, the higher the polarization degree of the composite film, but it is also easier to produce polarization saturation and polarization fatigue. This process is the most critical process, and there can be no sloppiness at all.
Because in this process, the spontaneous polarization direction of small molecule ferroelectric materials will really be fixed in the composite film to form a flexible electrical storage device with high energy storage density!
If you want to make flexible materials without energy storage problems
, polarization processing,
the slightest sloppy point!
“Ding!”
Finally… Smoothly, according to Lu Yu’s plan, a transparent flexible polymer film with a high dielectric constant was smoothly removed!
Next, it’s time to test your conjecture.
A dignified look flashed in Lu Yu’s eyes!
