In order to obtain information from outside, people must rely on sensory organs. The function of people's own sense organs is far from enough to study natural phenomena and laws and production activities. In order to adapt to this situation, a sensor is needed. Therefore, it can be said that sensors are the extension of human facial features, also known as electrical facial features.
With the advent of the new technological revolution, the world has entered the information age. In the process of using information, the first thing to solve is to obtain accurate and reliable information, and the sensor is the main way and means to obtain information in the field of nature and production.
In modern industrial production, especially in the process of automatic production, various sensors should be used to monitor and control the various parameters in the production process to make the equipment work in the normal state or the best state, and make the product achieve the best quality. It can be said that without many excellent sensors, modern production will lose its foundation.
In basic research, sensors are more prominent. The development of modern science and technology has entered a number of new fields: for example, the vast universe of thousands of light years should be observed on the macro level. On the microcosmic point of view, the particle world, which is small to FM, should be observed, and the evolution of the celestial bodies for hundreds of thousands of years is to be observed in the longitudinal direction, short to the instant reaction of the S. In addition, a variety of extreme technical research, such as ultra high temperature, ultra-low temperature, ultra high pressure, ultra high vacuum, super high magnetic field, ultra weak magnetic field, etc., have been developed to deepen the understanding of material, develop new energy and new materials. Obviously, it is impossible to obtain a large amount of information that human senses can not directly acquire. Many obstacles in basic scientific research are that the acquisition of object information is difficult, and some new mechanisms and the emergence of high sensitivity detection sensors often lead to breakthroughs in this field. The development of some sensors is often a pioneer in the development of some marginal disciplines.
Sensors have long been permeated to such extensive fields as industrial production, cosmic development, ocean exploration, environmental protection, resource investigation, medical diagnosis, biological engineering, and even the protection of cultural relics. It is no exaggeration to say, from the vast space, to the vast ocean, and to a variety of complex engineering systems, almost every modern project can not be separated from a variety of sensors.
It can be seen that the important role of sensor technology in developing the economy and promoting social progress is very obvious. All countries in the world attach great importance to the development of this field. I believe that in the near future, sensor technology will take a leap to reach a new level commensurate with its important status.
