Comparing the development history and research status of sensor technology, it can be seen that with the rapid development of science and technology and the maturation of related conditions, sensor technology has gradually received more attention from more people. Research on today's sensor technology and development, especially the development of new sensor technology based on photoelectric communication and biological principles, has become an important symbol and driving force for the progress of the country's and even the world's information industry.
Since the sensor has dynamic characteristics such as frequency response and step response, as well as static characteristics such as drift, repeatability, accuracy, sensitivity, resolution, and linearity, changes and turbulence in external factors will inevitably cause The small stability of the sensor's own characteristics will have a greater impact on its practical application, which requires us to focus on the working principle and structure of the sensor.
Stipulate corresponding basic requirements for sensors in small and medium-sized environments to optimize their performance parameters and indicators to the greatest extent, such as high sensitivity, anti-interference stability, linearity, easy adjustment, high precision, and no hysteresis. , long working life, repeatability, anti-aging, high response rate, resistance to environmental effects, interchangeability, low cost\wide measurement range\small size\light weight and high strength, etc.
At the same time, based on the analysis of the current research status of sensor technology at home and abroad and the ideal requirements for various performance parameters of sensors, the development trend of modern sensor technology can be analyzed and summarized from four aspects:
The first is to develop new materials, new processes and new sensors;
The second is to realize the multi-function, high precision, integration and intelligence of sensors;
The third is to realize the transmission of The miniaturization of sensing technology hardware systems and components;
The fourth is to achieve wireless networking through the cross-integration of sensors and other disciplines.

The development status of sensing technology:
Whether it is domestic or foreign, compared with computer technology and digital control technology, the development status of sensing technology Development lags behind them. Only in the 1980s did we begin to pay attention to and invest in the research and development of sensing technology or list it as a key research project. Many advanced results are still in the research and experimental stage, and the conversion rate is relatively low.
Our country has started research and development of sensor technology in the 1960s. After national research and development from the "Sixth Five-Year Plan" to the "Ninth Five-Year Plan", it has made great achievements in sensor research and development, design, manufacturing, reliability improvement, etc. Great progress.
A system for sensor research, development, production and application has been initially formed, and a number of gratifying invention patents and working condition monitoring systems or instruments have been achieved in the CNC machine tool research that have attracted worldwide attention.
But generally speaking, it cannot adapt to the rapid development of my country's economy and science and technology. Many sensors, signal processing and identification systems in our country still rely on imports.
At the same time, the market competitiveness of my country's sensing technology products has not yet been formed, product improvement and innovation are slow, and there is little innovation and improvement in production and application systems.
