The development of new sensors in China is a long way to go

In recent years, the rapid development of sensors is in the stage of transition from traditional to new sensors. The development of new sensors also depends on new sensitive materials, sensitive components and nanotechnology, such as a new generation of fiber optic sensors, superconducting sensors, focal plane display infrared detectors, biosensors, nanosensors, new quantum sensors, microgyroscopes, networked sensors , smart sensors, fuzzy sensors, multi-sensors, etc.

What are the characteristics of the new sensor? What is the difference between the traditional type and the new type sensor? The new sensors are characterized by miniaturization, digitization, intelligence, multi-functionalization, systematization, and networking. They not only promote the transformation of traditional industries, but also lead to the establishment of new industries. They are the new economic growth points in the 21st century. Miniaturization is based on micro-electro-mechanical system (MEMS) technology and has been successfully applied to form silicon pressure sensors on silicon devices.

The development of MEMS has raised the level of miniaturization, intelligence, multi-functionality and reliability of sensors to a new level. Sensor detection instrument, based on microelectronic technology, built-in microprocessor, or micro-sensor and microprocessor and related integrated circuits (operational amplifier, A/D or D/A, memory, network communication interface circuit) Such as packaged together to complete the digital, intelligent, networked, systematic.

Multi-sensor data fusion technology is forming hotspots. It was formed in the 1980s. It differs from general signal processing and also differs from single or multiple sensor monitoring and measurement. It is based on measurement results based on multiple sensors. High-level integrated decision-making process.

At present, there is still much room for development in China's sensor industry, and the integration of multiple functions further leads to convergence. This is an inevitable trend. Multi-sensor data fusion technology also promotes the development of sensor technology. The informatization of sensors and detectors will be an opportunity and a challenge. If seizing the information of sensors and detectors will be a key, and how to develop in the direction of internationalization, this will be a top priority.
