Prospects for the Application and Development Trends of Sensor Technology

Looking back at China after the reform and opening up, foreign industries and businesses have seized the market on a large scale, and the superiority of their technology and research level is self-evident. Although domestic research on sensor technology is gradually following suit and achieving remarkable results, the majority of the domestic sensor market still relies on imports. Therefore, the optimization of our sensor technology needs to be gradually refined, grasp future technological trends, and seek a breakthrough innovation to develop higher and more advanced sensor technology.
1. Aspects of sensor technology applications that can be encountered in daily life
1.1 The extensive application and safety of sensors in intelligent vehicles
In our daily life, we often hear the news about autonomous vehicle, which is the obvious application of sensors in the automotive field. Of course, the automatic driving here is not * automatic driving. Its intelligence can automatically drive in some areas with good road conditions, and can not replace people in busy and congested cities. This sensor is mainly used to detect the distance around the car to avoid accidents and other situations, and will start the vehicle after detecting the safe distance. The intelligent sensor that many cars still use now is an intelligent collision avoidance system. When the car is reversing, the rear sensor will measure the distance between the rear of the car and the obstacle, and then provide collision avoidance prompts. The safety, comfort, low pollution, and high fuel efficiency of automobiles are increasingly valued by society, and sensors in automobiles are equivalent to senses and antennae. Only they can accurately collect information on the working status of automobiles and improve the degree of automation. Automotive sensors are mainly distributed in engine control systems, chassis control systems, and body control systems.
1.2 Application in medical and personal health monitoring
With the gradual improvement of people's quality of life, those who have experienced the vicissitudes of the times are paying more and more attention to the level of medical care. They want to hold their health in their hands and always know their physical condition. This smart watch that can detect heart rate has emerged. By using a bracelet and watch to detect personal heart rate and pulse, this sensor can obtain heart rate and body fat by detecting the pulse and sweat on the wrist. Of course, to obtain more detailed body parameters, one still needs to go to the hospital for a comprehensive and systematic examination. However, this smart watch still has a huge market. Medical sensors, as the five senses that pick up vital sign information, are becoming increasingly important and widely used. For example, sensors are widely used in image processing, clinical chemistry testing, monitoring of vital sign parameters, diagnosis and treatment of respiratory, neurological, and cardiovascular diseases. Nowadays, sensors are widely used in modern medical instruments and equipment.
1.3 Applying sensors to industrial production and control processes
At any time, in order to develop a country's economic strength, it is necessary to revitalize the industry, improve industrial production processes and industrial production capacity. China's industrial production base is mainly in the north, and the application of sensors in industry also focuses more on the northern industry as a starting point. It is well known that manual operation in industrial production processes can easily generate errors. However, there is great potential in controlling the degree of machine operation through certain sensors. Distance sensors can enable each component to be operated at the same position, which can easily reduce the occurrence of errors; This is just one aspect of sensor applications in industry, and sensor technology is also used in CNC machine tools and intelligent installation systems. In the industrial production process, it is necessary to detect parameters such as temperature, pressure, flow rate, liquid level, and gas composition, diagnose various conditions of production equipment, and keep the production system in good condition to ensure product quality and improve efficiency. At present, the integration and penetration of sensors with microcomputers, communications, etc. make industrial monitoring automation more accurate and efficient.
In the future, prospects for the development direction of sensor technology
2.1 Development of integrated and efficient sensor core components
In the era of informatization, the speed of technological development and innovation is very fast. The intelligent systems of sensors that we feel now are very technological. However, after a period of time, current sensor technology may be eliminated. Therefore, we need to develop sensor technology in a more advanced direction. To develop sensor control, we need to invest in the development of integrated technology, such as integrating and controlling smart sensors in the home, optimizing the original control methods, installing integrated controllers at the door, automatically starting the smart sensors in the home after the owner returns, and providing certain services for the owner; Forming a comprehensive control port, which can be activated through a mobile phone or remote control to start the intelligent sweeping robot and use sensors to search for areas that need to be cleaned. The diversified parallel of the same function can achieve multidimensional and three-dimensional sensor parameters, and then integrate multiple single parameters in the sensor through software compilation, thereby completing centralized monitoring of multiple points or surfaces. The integration of sensor functions mainly aims to change the defect of single sensor function, and instead move towards the integration of multiple functions into a single sensor, realizing that one sensor can simultaneously monitor multiple signal changes, simplifying the monitoring system, and improving work efficiency.
2.2 Investment in research and development of new materials, development of new sensing materials
In industry, a new and more advanced material can often disrupt the entire market environment, and sensor technology, as the name suggests, its top priority is the core sensing material. The properties of the sensing material can ensure the accuracy of information, and in some high-precision fields, the transmission efficiency of the sensor has a great impact on the actual work results. Therefore, many companies choose to have sensors that transmit more materials. The choices of these enterprises also point out the direction for the further development of sensor technology. After experiencing silicon-based materials and superconducting materials, research and development of new conductive materials are also needed, not only to improve efficiency, but also to consider the cost of sensors and the practicality of materials. Intelligent materials refer to materials that already possess the functions of traditional sensors, capable of identifying and judging changes in external and self performance, and then taking corresponding actions to adapt to external changes and avoid damage to their own performance through certain functional transformations. Artificial intelligence materials have brought us a new world, with three characteristics: the ability to perceive changes in environmental conditions; Identification and judgment functions; The function of issuing commands and taking autonomous actions.
2.3 Developing towards intelligence and seizing the high intelligence sensing market
70% of China's sensor market is occupied by foreign sensor suppliers, mainly due to the late start of domestic sensor technology research and the insufficient depth of high-precision sensor research, which cannot fit the market well. Therefore, it has gradually been squeezed out of the market. However, now is the era of technological explosion, and the replacement rate has greatly increased. In the future, more intelligent sensor technology will definitely help Chinese local sensor companies regain the market. However, we need to make efforts to invest in research on intelligent sensor systems, and the products produced cannot be semi-automatic intelligent sensor technology like today's autonomous driving technology. They must be able to break away from manual operation in industrial production lines, and only be managed by manual labor. Sensor technology should be combined with computer control, A device that integrates sensors and computers on a single chip, combining sensitive technology and information processing technology. In addition to innate perception, it also has cognitive abilities. Gradually integrating artificial intelligence technology into sensor technology, creating various highly intelligent sensors based on fuzzy reasoning and artificial neural networks, and improving the sensitivity and control effectiveness of sensors.
3 Conclusion
*As we all know, the world is changing, and the development of sensor technology has a history of several decades. At first, it was based on sensing changes in simple physical characteristics such as weight, temperature, humidity, etc. This type of sensor was also widely used. Later, with the popularity of microcomputers, microprocessing systems, and sensor technology, early intelligent sensors were formed. The development of sensor technology has been carried out gradually through practice, optimizing and improving some details, making this technology widely applied, not only in daily life, but also in the military field. It is necessary to seek more optimized sensing technology in the future development to improve its efficiency and quality of work.
