The topic includes the largest gap in the prospective materials of the World Artificial Intelligence Conference, and the process is also a big problem.  Sheng Changlin New Finance Observer reporter pays attention to Internet financial innovation Dong Yonggui, a professor at the Department of Precision Instruments of Tsinghua University, introduced that China has roughly started since 1980 Pay attention to the research of sensor technology. After years of efforts, the level of development in loadcell research is still relatively good. However, the technological progress in productization is not very satisfactory. In fact, the domestic laboratory research level of many loadcell technologies is not very poor, but unfortunately they have not been fully utilized and have not been transformed into mature products entering the market. He said that the research on loadcell technology requires a relatively long investment. The research and development of a loadcell takes 6 to 8 years to mature. Generally, Chinese companies cannot afford such a long period. Chinese companies are more vulnerable to failure, and the risk of failure in loadcell research is high. According to what Dong Yonggui learned during his visit to Japan, many of the research and development supported by Japanese companies cannot be formed into products, but the companies can afford it. Only 2-3 of the 10 items can be turned into products. "In contrast, many of our companies are preparing to take what others have." Dong Yonggui said that this kind of thinking is problematic, including that we always hope to introduce foreign talents who have their own projects. "I don't plan to raise fish, but to fish for a fish." Compared with relatively large instruments and equipment, the investment required for loadcells in the process of commercialization is generally not large, so it is more suitable for small enterprises to invest. In this regard, China should have an advantage. However, this is also a disadvantage if you consider it another way. A feature of the loadcell industry is that the loadcell itself has a high technical content, but the price of a single loadcell is generally not high. One result of this feature is that, although the technical added value of the loadcell is high, it is difficult to form a considerable output value simply by relying on the sensor. According to Professor Dong Yonggui's analogy, the sensor is a bit like the "medicine lead" in traditional Chinese medicine. Its function is very important, but the real scale needs to rely on the whole medicine. Once many foreign sensor companies have a breakthrough in a certain sensor, related measuring instruments will be developed soon. Moreover, under China's patent protection mechanism, the key technologies that have been painstakingly developed in sensors often show a "know-how" nature. After being plagiarized, it is difficult to explain clearly, and companies cannot afford to file lawsuits. Although there are also MEMS sensor companies in China, they are all commissioned to process them. If they are not good, they will be used by the processing companies themselves. The current corporate innovation system has great problems. In 2012, a senior in the domestic sensor field said at a meeting that the reason why China's sensor industry is not developing well is that there is a lack of leaders who can give lectures to the State Council. The research and development in this field is long and the degree of significance is not enough. Small things are based on physical phenomena that were discovered decades or hundreds of years ago. The scholar pointed out that this kind of research is actually very laborious. For example, there is an acceleration sensor used in the oil industry for seismic wave measurement. It is based on the principle proposed by the Soviet Union decades ago, but it was not until the collapse of the Soviet Union. Only after arriving in the United States was the product formed and applied. "The more we need to accumulate more and grow more, and grow more and earn less, the greater the gap between us." Dong Yonggui believes that the gap is now on the trend of further widening.
