In recent years, developed countries in the world have attached great importance to the development of sensor technology, and the rapid development of sensor technology has made the research on new principles, new materials and new technologies of sensors more in-depth and extensive, and new varieties, new structures and new applications of sensors have continuously emerged and emerged one after another.
At present, sensors have quickly entered many occasions such as automobiles, airplanes, medical products, office machines, personal computers, household appliances, and pollution control. In recent years, the world sensor market has maintained an annual growth rate of about 10% or even higher. The demand for high-tech products is more and more year by year. The demand for sensors and the direction of development are mainly concentrated in the following aspects.
1. Industrial process control and automotive sensors
It is necessary to focus on the development of new types of smart sensors such as pressure, temperature, flow, distance, and sensors with protocol functions, electronic injection systems, exhaust circulation devices, and sensors for automatic driving. Modern luxury cars need sensors to accurately measure temperature, pressure, position, distance, speed, acceleration, attitude, flow, humidity, electromagnetic, photoelectric, gas, vibration, etc., and the quality and quantity of the sensors used determine their electronics The key to the level of the control system.
2. Ecological agriculture sensor
Ecological agriculture is a knowledge-intensive and technology-intensive field. At present, the sensing technology as an "electronic sensor" has been widely used in agricultural production, biological research, and pesticide residue detection.
3. Environmental protection sensor
Focus on the development of water quality monitoring, air pollution and industrial pollution control sensors. People are paying more and more attention to the protection and management of the natural environment in which they live, and sensor technology will play a significant role in the monitoring of key areas, river basins, sea areas and atmospheric environment.
4. Miniature sensors and MEMS (Micro Electro Mechanical System)
Micro-electromechanical systems (MEMS) originated from micro-silicon sensors, and when MEMS technology emerged, it in turn greatly promoted the technological progress of micro-silicon sensors and made various types of sensors to be miniaturized. For example, the miniature pressure sensor is the most mature and the earliest commercialized sensor among MEMS devices. It can be used to monitor parameters such as environment, aviation (speed, air data, altitude), and medical treatment (direct measurement of blood vessel pressure).
Sensors based on MEMS technology have been gradually put into practical use, and have huge application prospects in various fields such as industry, agriculture, national defense, aerospace, navigation, medicine, bioengineering, transportation, and home services.
5. New sensors urgently needed in biological and medical research
At present, medical sensors mainly include sensors in the field of image diagnosis and sensors in the field of clinical testing. The development of life sciences requires a variety of biomass sensors, such as sensors for enzymes, immunity, microorganisms, cells, DNA, RAN, proteins, smell, taste, and body fluid components, as well as physiological sensors such as blood gas, blood pressure, blood flow, and pulse. Practical sensor for volume detection.
6. Medical and food monitoring sensors
Focus on the development of biological and chemical sensors for the diagnosis and treatment of various diseases, food fermentation and enzyme sensors, and the development of related sensors and biosensors suitable for home medical services.
