In order to obtain information from the outside world, people must rely on the sensory organs. And by relying on people's own sensory organs, their functions in studying natural phenomena and laws and producing flows are far from enough. To accommodate this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of the human five senses, also known as electric five senses.
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 be solved is to obtain correct and reliable information, and the sensor is the main way and means to obtain information in the natural and production fields.
In the production of modern industries, especially in the automated production process, various sensors are used to supervise and control the various parameters in the production process, so that the equipment works in a normal state or in an optimal state, and the products are of the best quality. Therefore, it can be said that without many excellent sensors, modern production will lose its foundation.
In basic research, sensors have a more prominent position. The development of modern science and technology has entered many new fields: for example, to observe the universe of thousands of light years on a macroscopic level, to observe the particle world as small as cm on the microscopic level, and to observe the evolution of celestial bodies for hundreds of thousands of years in the vertical direction. , an instant response as short as s. In addition, various extreme technologies such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, super-strong magnetic field, ultra-weak magnetic enthalpy, etc., which are important for deepening material familiarity, developing new energy, and new materials, have also emerged. Wait. Obviously, it is impossible to obtain information that is not directly accessible to human senses, and that there is no suitable sensor. The obstacles of many basic scientific research are firstly that there are problems in the acquisition of object information, and some new mechanisms and the emergence of highly agile detection sensors often lead to breakthroughs in this field. The development of some sensors is often the forerunner of some edge discipline development.
Sensors have long penetrated into areas such as industrial production, space development, ocean exploration, environmental protection, resource surveys, medical diagnostics, bioengineering, and even cultural relics protection. It is no exaggeration to say that from the vast space, to the vast ocean, to all kinds 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 improvement is very significant. All countries in the world are facing the development of this field. It is believed that in the near future, sensor technology will have a rush to reach a new level that is equivalent to its important position.
