Sensor technology development

The current development of sensors tends to be a kind of convergent development, and the overall technology is an integrated multi-functional development trend.

Sensor technology is the cutting-edge technology of modern science and an important technological foundation for the new technology revolution and the information society. In modern life and scientific research, a wide range of reliable and accurate information provided by various types of sensors can not only replace the five functions of human beings, but also detect information that cannot be felt by human facial features, thus enabling human beings to A good understanding of the world and the transformation of the world.

At the same time, the market outlook is very promising given the large increase in the current sensor market. However, in order to better adapt to the needs of future social development, the sensor technology is also in continuous progress. Here is a prediction of the direction of sensor technology development:

1. Discover new phenomena, develop new materials, new phenomena, new principles, and new materials are important foundations for developing sensor technology and researching new sensors. The discovery of each new principle and new material will be accompanied by the birth of new sensor types. .

2. Integration and multi-functionalization: The development of sensor integration for sensitive functional devices, and the recent active application of semiconductor integrated circuit technology and its development ideas for sensor manufacturing. For example, micro-sensors are fabricated using micro-electro-mechanical systems (MEMS); sensors are made using thick-film and thin-film technologies.

3. Challenges to untapped areas - biosensors have so far been studied vigorously. Most of the sensors developed are physical sensors, and chemical sensors and biosensors should be actively developed in the future. In particular, the development of intelligent robot technology requires the development of various sensors that simulate the human sense organs, such as existing robot force sensors, tactile sensors, and taste sensors.

4, Smart Sensor (Smartsensor) - with judgment ability, learning ability sensor. In fact is a sensor with a microprocessor, it has detection, judgment and information processing capabilities.

Wireless sensing is the most important new technology emerging in process measurement for decades. Although wireless measurement has proven to be faster than most in industrial applications, wireless continues to grow far faster than the overall automation market. In the past year, the most impressive thing was the changes in wireless sensor networks (WSNs) and the more mature new technologies.

At the same time, the multi-sensor data fusion technology is increasingly attracting everyone's attention. It is based on the measurement results of multiple sensors, to achieve a higher level of comprehensive decision-making. In view of the increase in the miniaturization, intelligence and multi-functionality of sensors, the information obtained will be greatly increased. Further integration of multiple functions will result in an inevitable trend of development. This will also promote the development of sensor technology from the side. .
