The official account of "brother sensor" for the Internet of things, "sensors for national purposes," was sent to chat about sensors in the leisure time of business trip (81), because the number of 10 o'clock at night was forgotten. At the same time, there is also an error. A friend pointed out that the temperature range of the pressure sensor is "higher than 150 degrees". Instead of 1150 degrees, I wrote an extra 1. Thank you for your correction.

       I came to Nanjing in a hurry to attend the sensor Summit Forum and annual meeting organized by the sensitive components and sensors branch of China Electronic Components Association. At the same time, the general meeting of the sensitivity branch was held, and Xi'an Zhongxing measurement and control company was re elected as the vice chairman of the sensitivity and sensor branch of the 9th China Electronic Components Association.

        Because of the epidemic, the summit also had twists and turns. It was postponed three times and finally took place. Old friends I haven't seen for more than two years are very happy to meet and communicate again. The content of the summit is very rich. There are not only the farsighted and eloquent views of academicians, professors and experts, but also the grounding thinking and analysis of actual sensor workers, puzzles and problems. I believe participants from all over the world will have their own gains.

       This article is about official account. I want to talk about the present and future of sensors and medical health.

       COVID-19 has been spreading around the world for two years, and China has a very strict administration. From once a week to only 48 hours or even 24 hours now, the first thing to do after a business trip is to ask where there is a nucleic acid test point. Nucleic acid, is it cost-effective? No, isn't it cost-effective?

       Can we make sensors invent a sensor? Preferably portable, wireless transmission is better. Can we judge whether the person is negative or positive by personal exhalation or saliva in time or within half an hour. In this way, our people, especially those who travel on business, will save much trouble and time, and social efficiency will be greatly improved. Unfortunately, I don't engage in gas sensors or biosensors. I'm really worried.

       Yesterday, academician Du of Nanjing University gave a speech on magnetic sensors, which inspired us.

       With the improvement of the resolution and accuracy of magnetic sensors and people's understanding of the magnetic field intensity of various parts of the human body, we can make a lot of cardiac magnetic detectors, brain magnetic detectors, bone magnetic detectors based on the magnetic principle, and even detect the change of the whole body magnetic field distribution to understand the condition of the disease in the future. The change of the magnetic field is easier to detect than the change of the current, And it's non-contact. In some specific circumstances, people can be tested without perception.

        President Guo Yuansheng and President Guo mentioned in different places that there is a bucket in the toilet in Japan, with a variety of sensors built in. Through your daily excretion of feces, you can detect more than a dozen different diseases and find them early. Whether it's the latest scientific research or something that has been applied, why doesn't anyone do it in our country? Is it a cost issue? Or a technical problem? Or our people's concept, the traditional concept of Chinese people is to pay attention to treatment? Light prevention, would rather spend ten thousand yuan for treatment than one hundred yuan for prevention. I hope relevant researchers can do these things. Even if there are fewer diseases diagnosed in Japan, it is worth trying.

       Sun Xuhui, chairman of Suzhou Huiwen Technology Co., Ltd., who is engaged in gas sensors, gave a speech on "artificial olfactory platform based on MEMS nanotechnology gas sensors", which can sense the "freshness" of vegetables in the refrigerator and the "aroma" in the process of tea frying. In the future, there will be more achievements in the field of medical and health care. Study the molecular content of exhaled gas of cancer patients, or gastric cancer or lung cancer. Medical scientists and sensor experts work together. I believe such instruments and equipment will appear in the future. It is expected that Chinese gas sensor experts can develop a composite gas sensor with the same sensitivity as "dog nose", and such a problem will be solved. It is expected that "electronic nose" will appear soon.

       In this regard, I hope we can pay more attention. Maybe we can catch up with the world's leading level.

Health is the biggest thing in life. Sensor is a promising industrial technology in the future. The combination of the two is just like other industries. Our high-end medical workers and our high-end sensor scientists and engineers should work together.
