New sensitive materials are the technological foundation of sensors, and material technology research and development is an important means to improve performance, reduce costs, and upgrade technology. In addition to traditional semiconductor materials and Optical fiber, organic sensitive materials, ceramic materials, superconductors, nanomaterials and biomaterials have become research and development hotspots, and new sensors such as biosensors, optical fiber sensors, Gas detector and digital sensors have accelerated to emerge. Fiber optic sensors are sensors that utilize the sensitive functions of optical fibers themselves or transmit light waves using optical fibers. They have high sensitivity, strong resistance to electromagnetic interference, corrosion resistance, good insulation, small size, and low power consumption. Currently, the applied fiber optic sensors can measure more than 70 physical quantities, with broad development prospects; The Gas detector can convert the measured gas concentration into electricity output that has a certain relationship with it. It has the characteristics of good stability, good repeatability, good dynamic characteristics, rapid response, convenient use and maintenance, and is widely used.
In recent years, flow sensors, pressure sensors, and temperature sensors have the largest market size in China, accounting for 21%, 19%, and 14% of the entire sensor market, respectively; Pressure sensors, temperature sensors, flow sensors, and level sensors have shown the characteristics of mature markets. It is expected that the main growth in the future sensor market will come from emerging sensors such as wireless sensors, microsystem sensors, and biosensors. Sensors have entered people’s daily work and family life, and have been widely applied in various sectors of the national economy and national defense construction, making due contributions to China’s modernization construction.
An intelligent sensor is a product that combines one or more sensitive components, microprocessors, peripheral control and communication circuits, and intelligent software systems. It has functions such as monitoring, judgment, and information processing. Compared with traditional sensors, it has many characteristics. For example, it can determine the working status of sensors and correct measurement data to reduce errors caused by environmental factors such as temperature and humidity; It can solve hardware difficult problems with software; It can complete data calculation and processing work, etc. Moreover, the accuracy, range coverage, signal-to-noise ratio, intelligence level, remote maintainability, accuracy, stability, reliability, and interchangeability of intelligent sensors are far higher than those of ordinary sensors.
