In order to obtain information from the outside world, people must rely on their sense organs. And relying solely on people’s own sensory organs, their success in studying natural phenomena and laws and production activities is far from enough. In order to adapt to this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of human features, so it is also called an electrical feature. The arrival of the new technological revolution has gradually entered the information age. In the process of using information, the first thing to solve is to obtain accurate and reliable information, and sensors are an important way to acquire information in the nature and production fields. In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters of the production process so that the equipment can work in a normal state and the product can achieve top quality. Therefore, it can be said that without a large number of excellent sensors, modern production also lost its foundation. In basic scientific research, sensors have a more prominent position. The development of modern science and technology has entered many new fields: for example, macroscopic observation of the vast universe of thousands of light years, microscopic observation of particle worlds as small as nm, and vertical observation of the evolution of celestial bodies for hundreds of thousands of years Short response to s. In addition, there have also emerged various kinds of extreme technological researches that have an important role in deepening the understanding of materials, exploiting new energy, and new materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, super magnetic field, and ultra-weak magnetic field. Obviously, to get a lot of information that human senses cannot directly obtain, there is no suitable sensor. Obstacles to many basic scientific researches are the difficulty in obtaining object information. The emergence of new and highly sensitive detection sensors often leads to breakthroughs in this field. The development of some sensors is often a pioneer in the development of marginal disciplines. Sensors have already penetrated into an extremely wide range of fields such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, and biological engineering. It is no exaggeration to say that from the vastness of space, to the vastness of the oceans, and to a variety of complex engineering systems, almost every modern project cannot be separated from a variety of sensors. Such as: load cell. From this we can see that the important role of sensor technology in economic development and social progress is very clear. All countries in the world attach great importance to the development of this field. It is believed that in the near future, the sensor will undergo a qualitative leap, reaching a level commensurate with its important position.
