Chapter 113 Ultra-Micro Optically Pumped Magnetometer Sensor

This hollow helmet looks very similar to the 'first generation deep sleep aid' on the surface, and still has a clear black and white design.

It’s just that compared to the ‘first generation deep sleep aid’, the back of the head seems to have been partially flattened, making it more suitable for sleeping on your back.

"This is our second-generation deep sleep aid. In addition to the huge improvement in chip performance compared to the previous generation, the biggest change is the use of a brand new sensor.

Of course, the improvement in software control is also very great, but these things cannot be simply described in words, and can only be experienced when you use it. "

When Lin Feng finished speaking, the relevant hardware parameters were also displayed on it.

Among them, the processor of this second-generation deep sleep aid device uses the Huawei Kirin 920 mobile phone processor that was just released this year.

Although this processor is a mobile phone processor and not a dedicated processor, it is sufficient to assist the artificial intelligence Jarvis.

After all, the performance of the Kirin 920 mobile phone processor can compete with the Qualcomm Snapdragon 801 mobile phone processor of the same generation.

After that, people's eyes continued to move downwards, and the pupils of many people who knew about sensors and instruments suddenly shrank.

Because they actually saw the special term "ultra-micro optically pumped magnetometer sensor". How could people's faces not change when they learned what "optically pumped magnetometer" is?
Because the 'optically pumped magnetometer' is also a well-known thing, it is widely used in aeromagnetic survey, ocean monitoring, geological exploration, mineral resource development, archaeology, earthquake prediction, medical treatment, health...

It can be said that since this thing was invented, it has fully demonstrated its application value and prospects.

During this period, many researchers have tried to miniaturize and micro-scale it to expand its market use, but no major breakthrough has been made so far.

Look at the appearance of the helmet at this time, especially the thickness which is no more than the width of a thumb nail.

This means that the size of the 'ultra-micro optically pumped magnetometer sensor' should be very small, and the total volume must not exceed the width of a little finger nail!
If this is true, it means that this thing has a great future and can be applied in many fields that require magnetic detection.

It is estimated that it is possible to earn tens of millions of dollars a year just by selling this "ultra-micro optically pumped magnetometer sensor".

I just don't know what the magnetic detection accuracy of this so-called 'ultra-micro optical pumping magnetometer sensor' is, and whether it can achieve the ultra-high magnetic detection accuracy of a standard optical pumping magnetometer.

Following people's curiosity, Lin Feng quickly introduced the 'ultra-micro optically pumped magnetometer sensor'.

"...The next thing I'm going to introduce is the 'ultra-micro optical pump magnetometer sensor'. To be honest, this thing is the most valuable thing in the entire deep sleep aid device.

Because it can not only accurately measure the current brain wave state, but also measure the brain condition to check whether the brain has abnormal proliferation, tumors, epilepsy, dementia or other mental illnesses.

In some ways, this thing is a magnetoencephalogram (MEG) instrument, but our main purpose is not to use it to detect brain disease.

Instead, it is used to detect the state of the brain and brain wave data, and provide it to the artificial intelligence Jarvis for analysis.

Finally, the artificial intelligence Jarvis uses special sound waves and light signals to help people fall asleep quickly and develop a deep sleep aid.

So this 'ultra-micro optically pumped magnetometer sensor' is the most important thing in the entire deep sleep device.

After all, if you want to catch an eagle, you must first be able to see where the eagle is. The detection accuracy of the first-generation deep sleep aid cannot do this, so naturally there is no way to achieve a higher level of deep sleep aid effect. "

After hearing Lin Feng's words, the netizens in the live broadcast room and the reporters on the scene were confused, but they instinctively felt that it was amazing. And what Lin Feng said seemed to be correct. If you want to better control the brain to reach the specified brain wave state, you should indeed use more accurate detection equipment.

Moreover, the function that Lin Feng just mentioned, which is to detect whether the brain has abnormal proliferation, tumors, epilepsy, dementia or other mental illnesses, seems to be very powerful.

By using this second-generation deep sleep aid, if the brain develops a disease in the future, wouldn’t it be possible to detect and treat it in advance?
Thinking of this, their gazes towards the second-generation deep sleep aid became even more enthusiastic.

But amidst the eager eyes, a hand suddenly raised among the experts. People turned their heads and found that the person who raised the hand was Professor Jacobs.

"Does Professor Jacobs have anything to say?"

Lin Feng asked Professor Jacobs, and Professor Jacobs's mouth curled slightly, and then he smiled in front of everyone and the live broadcast room:

"Mr. Lin Feng, as far as I know, the optically pumped magnetometer has a very high magnetic detection accuracy, even comparable to the SQUID superconducting magnetometer.

But the problem is that the optically pumped magnetometer has a fatal problem, which is that it is easily disturbed by external magnetic forces.

For example, our earth is a super large magnetic field, our mobile phones are also a magnetic field, our televisions are also a magnetic field, and even electrical wires are a magnetic field.

In this case, finding the magnetic force of brain waves among these countless magnetic fields is no less difficult than hearing the sound of a needle falling in a noisy street.

It is true that you can add more ears to improve your hearing, but no matter how much you improve, there is a limit.

So I think this so-called 'ultra-miniature optically pumped magnetometer sensor' is a joke, and I'm not optimistic about how well it can perform under the huge 'environmental background noise'.

Of course, if you want to build a special low-magnetic interference environment, then just ignore what I said, but as far as I know, this second-generation deep sleep aid will be sold publicly.

You can't ask every consumer to spend time and money to build a special low-magnetic interference indoor room, right? "

When Professor Jacobs' words were heard, there was an uproar at the scene, and the live broadcast room was instantly in chaos.

Because after hearing Professor Jacobs' words, their perception that the 'ultra-micro optically pumped magnetometer sensor' was mysterious and powerful suddenly collapsed.

Only then did they realize from Professor Jacobs' words that the 'ultra-micro optically pumped magnetometer sensor' could be so easily interfered with by the outside world.

But if you think about it carefully, although there are electrical signals when brain neurons communicate, these electrical signals are ultimately too weak, and the magnetic field generated is naturally weak, which is indeed too weak compared to the ambient magnetic field.

In this case, the 'ultra-miniature optically pumped magnetometer sensor' does face huge environmental magnetic interference problems, which ultimately leads to poor brain wave detection results.

"Professor Jacobs is worthy of being a professor at Harvard Medical School. He is also very knowledgeable about optically pumped magnetometers.

Yes, the 'ultra-miniature optically pumped magnetometer sensor' is indeed easily disturbed by external magnetic forces.

But Professor Jacobs, can we as the R&D party not think of the problem you can think of? We dare to launch the second generation of deep sleep aid and prepare to sell it, which naturally solves this problem. "

When Lin Feng finished speaking, two technical terms appeared on the projection screen behind him.
