In an information-based society, almost no development or application of science and technology can be supported by remote sensor and signal detection technologies. People living in the information age are most closely related to the development, collection, transmission, and processing of information resources. With the development of science and technology, sensors are constantly updated and developed.

With regard to the development direction in the current state of technology, sensors are moving toward the direction of integration, intelligence, multi-function, and networking. Sensor integration refers to the parallelization or multi-function integration of multiple components of the same function; the multifunctionality of the sensor is also one of its development directions. Not only can the production cost be reduced, the volume can be reduced, and the stability of the sensor can be effectively improved. Reliability and other performance indicators. As far as the current state of the art technology is concerned, microsensors have had a profound impact on signal detection systems in a large number of different applications, such as aerospace, long-range detection, medical and industrial automation. Currently, microsensors that have been developed and put into practical use are now available. Used to measure various physical quantities, chemical quantities, and biomass, such as displacement, velocity/acceleration, pressure, stress, strain, acoustic, optical, electrical, magnetic, thermal, pH, ion concentration, and biomolecule concentration.

Gongkong boldly predicts that the sensor market will start to rise in the next five years. First, the sensor has become the bottleneck in the development of China's Internet of Things, and localization requirements are urgent. The development of China's sensor industry is lagging behind. Domestic sensor demand, especially high-end demand, is heavily dependent on imports. Localization gap is huge. At present, sensor imports account for 80%, and sensor chip imports account for 90%.

The second is that the sensor is the foundation for information gathering in the Internet of Things. It is in the upper reaches of the industrial chain and benefits greatly at the beginning of the development of the Internet of Things. At the same time, the sensor is in the tower of the Internet of Things pyramid, which will be the largest and most basic in the entire Internet of Things industry. The link. According to the “12th Five-Year Plan” of the Internet of Things that was written in the early days, it is expected that by 2015 there will be an industry with core technologies of 200 billion yuan, of which the sensor will be 10 billion yuan and the system and testing will be 70 billion yuan.

In the future, the sensor industry will achieve high growth from point to point and the domestic market will grow by 30% annually. The Internet of Things (IoT) industry has entered the market introduction period. With the intensive introduction of relevant supporting policies, the compound annual growth of the domestic sensor market will reach 31% in the next five years.
