The main function of the sensor


In the research of basic disciplines, sensors have a prominent position. The development of modern science and technology has entered many new fields: for example, it is necessary to observe the vast universe of thousands of light years at the macro level, the world of particles as small as fm at the micro level, and the evolution of celestial bodies over hundreds of thousands of years in the vertical view. , An instant response as short as s. In addition, various extreme technology researches, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, ultra-weak magnetic field, etc., which play an important role in deepening material understanding, opening up new energy and new materials, have emerged. Obviously, it is impossible to obtain a large amount of information that cannot be directly obtained by the human senses without a suitable sensor. The obstacles to many basic scientific researches are, first of all, the difficulty in obtaining object information. The emergence of some new mechanisms and high-sensitivity detection sensors often leads to breakthroughs in this field. The development of some sensors is often the pioneer of the development of some marginal subjects.


Sensors have already penetrated into a wide range of fields such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relic 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 is inseparable from a variety of sensors.


It can be seen that the important role of sensor technology in economic development and social progress is very obvious. Countries all over the world attach great importance to the development of this field. It is believed that in the near future, sensor technology will take a leap, reaching a new level commensurate with its important status.


The main features of the sensor


The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-functionalization, systemization, and networking. It not only promotes the transformation and upgrading of traditional industries, but also may establish new industries, thus becoming the new industry in the 21st century. Point of economic growth. Miniaturization is based on the micro-electromechanical system (MEMS) technology and has been successfully applied to silicon devices to make silicon pressure sensors.
