Chapter 122 Qualitative and Quantitative
"Let me change it, what can I change it to? We don't mention real micron tweezers, what are we talking about?" the female assistant asked.

"Change to."

The bald middle-aged man thought for a while, "Use a one-micron photolithography machine to reproduce thermally retractable tweezers."

"How can such a thesis topic be attractive?"

The female assistant was very dissatisfied.
-
Just like when the enlarged micro-motor came out in 88, there was a wave of motor fever in the world. There are more than one tweezers-related projects participating in this conference.Many people are making similar changes.

Chen Quan's four tweezers are equivalent to a summary, which has reached another level.If someone attacks with equipment precision, it will arouse everyone's disgust.

In addition, many companies have published papers under the banner of True Micron, which is equivalent to sharing the attention.If there are too many things, they are worthless.

The wave of micron tweezers, in fact, is just a while, it has passed, that is to say, it has passed.As for whether the tweezers are real microns or false microns, does anyone really care?
This group of true micron tweezers, apart from falling into homogeneous competition, also lacks an attractive main photo.

Chen Quan's thesis was a shocking success, and the photo of cells being grabbed by tweezers accounted for at least 4% of the success.

No need for a text, the photo itself is an excellent piece of news and hot spots, with its own traffic.

Before this picture came out, the popularity of MEMS technology had a lot to do with another widely circulated picture.

That's a photo of a mite crawling on a Micron gear set.

Mites, which are invisible to the naked eye, are like giants compared with micron-level MEMS components.The strong contrast contained in it is impressive.

But similar photos can't be taken just because you want to.

After adopting a 1-micron photolithography machine, the size of the tweezers has been reduced by 20 times. Correspondingly, the difficulty of grasping cells has increased by more than [-] times.
The size of the cells ranges from large to small, the large ones are over 100 microns, and the small ones are as small as 0.1 microns. It is not difficult to find matching small cells, but it is difficult to catch them.

Can't design a system that automatically captures cells to take this picture.

Even if it can be done, it is not a matter of a month or two months.

If Chen Quan hadn't used a 20-micron lithography machine, used plant cells with a diameter of nearly [-] microns, and used traditional optical microscopes and manual operations to grasp the cells at the level of Feng Yan's group of novices, it would not be possible at all. possible.

How can we know that it is not a blessing if it is a blessing in disguise? ——
In the corridor, at the entrance of the venue.

"Here is Emilia from Hanseatic TV [-], reporting on the spot for you. You can clearly see that behind me, there are explosive scientific research results just after the start of the MEMS conference."

A professional woman in her 20s, holding a microphone. "We were honored to invite an expert in the field of MEMS, Professor Fisher. Professor Fisher, can you explain what happened in the venue?"

A tall, thin white man in his early forties, who looked like a scholar, took the microphone. "The genius Mr. Chen Quan showed two sets of extremely complex actuator structures. These two structures have never been seen before, so they caused a sensation."

"Professor Fisher, can you explain in more detail why these two structures caused a sensation? I believe audience friends will be more interested in this."

"That's right. Electromagnetic drive is very common in our daily life because it has the highest power and efficiency. But it is the first time it has appeared in MEMS.

How to manufacture micro-coils in such a small space is a world-class problem.But for this problem, Mr. Chen Quan showed his solution ideas through examples. "

"You just said two kinds?"

"Yes, the other is inverse piezoelectricity. The principle of inverse piezoelectricity is to apply electricity to the material, and corresponding mechanical stress will be generated inside it. As long as the voltage is large enough, displacement can be generated. Then through a series of lever principles , amplifying this displacement can also achieve the effect of the actuator.”

The white professor explained patiently. "The biggest difficulty of the inverse piezoelectric structure is how to deal with the problem of voltage insulation at the micron level. The second difficulty lies in the design of the lever mechanism"

"Professor Fisher, Professor Fisher!"

At the prompt of the photographer, the female reporter had to interrupt forcibly. "Can you use some qualitative, quantitative words."

"Qualitative, quantitative?"

"Yes. For example, what was created, what was ahead, what era was opened and so on."

The female reporter kept hinting and inducing.

"Then I can only say that Mr. Chen Quan's paper has created the electromagnetic era and inverse piezoelectric era of MEMS."

"Uh……"

The female reporter scratched her head. "But I still don't understand. Can you use more colloquial language?"

"A more colloquial language?"

"For example, Mr. Chen Quan's last paper, the photo of micron tweezers grabbing cells, is recognized as having equipped hands and feet for micro-robots. This time, the three tweezers are for robots. what?"

"Hmm. Let me think about it."

The lanky Professor Fisher was lost in thought.

"If you have to be anthropomorphic, then we can say that the electromagnetic force MEMS actuator adds a heart to the robot. And inverse piezoelectricity?"

　Today, I released two chapters in one breath.Although it is two small chapters, it is a heart.
