Connecting all things, sensing the future!

 

A sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, Records and controls,
etc.

 

Sensors can be roughly divided into temperature and humidity sensors, pressure sensors , image sensors, light sensors, position sensors, gravity sensors, and the like
.
Pressure, temperature, concentration, you can think of data, almost all can be measured with sensors
.

 

The role of sensors in the era of intelligent networking cannot be ignored
.
It is widely used in industry, communication electronics industry, automotive electronics, communication electronics, consumer electronics and other fields
.

 

Since its birth, sensors have roughly gone through three stages of development: structural sensors, solid (integrated) sensors, and smart sensors
.

 

　　The so-called intelligent sensor means that it has certain detection, self-diagnosis, data processing and adaptive capabilities for external information, and is the product of the combination of microcomputer technology and detection technology
.

 

　　Application scenarios of smart sensors

 

　　1.
Smartphone

 

　　The more common smart sensors in smartphones now include distance sensors, light sensors, gravity sensors, fingerprint recognition sensors, image sensors, three-axis gyroscopes, and electronic compasses
.

 

　　2.
Autopilot

 

　　Autonomous driving is the current pursuit of many car companies.
At present, there are still many obstacles to achieve L5-level autonomous driving, and the realization of "unmanned driving" in the true sense must rely on continuous breakthroughs in intelligent sensor technology
.

 

　　3.
Artificial Intelligence

 

　　Sensors are an important way for people to obtain information, and artificial intelligence needs to obtain surrounding information through many sensors
.
Smart sensors can enable artificial intelligence to collect a large amount of information from the outside world, thereby providing information reference for artificial intelligence to make judgments
.

 

　　4.
Smart wearables

 

　　Wearables are making great strides in both personal and medical use today, and it's not possible without smart sensors
.
The information collected by the smart sensor provides data support for individuals or institutions to grasp the wearer's body information and make scientific and effective medical guidance
.

 

　　In the era of Industry 4.
0, the role of smart sensors has become increasingly prominent.
As an important foundation for the era of intelligent networking, sensors themselves are in a state of rapid development
.
The industries and industries related to sensors are also developing in an orderly manner
.

 

　　Raw materials and basic components are in high demand
.
The upstream of the sensor is chips, circuits, power supplies, and sensitive components; under the influence of the demand for smart sensors, the market for chips and circuits has also been expanded
.
According to the statistics of China Nonferrous Metals Industry Association, in 2021, China's industrial silicon output will be 2.
61 million tons, a year-on-year increase of 24.
3%; driven by the demand from the photovoltaic industry, domestic consumption will be 1.
86 million tons, a year-on-year increase of 12.
7%
.
The market demand for chips is strong
.
According to the Semiconductor Industry Association (SIA), global chip sales in 2021 will reach $555.
9 billion, a year-on-year increase of 26.
2% and a record high
.
The association expects chip sales to grow 8.
8% in 2022 as chip manufacturing continues to expand capacity to meet demand
.

 

　　my country's policy support

 

　　It is precisely because of the prominent role of sensors in the era of intelligent networking that the state and local governments have also introduced a series of policy measures to encourage and support the development of intelligent sensors
.

 

　　On March 4, 2022, the Ministry of Science and Technology issued the "Notice on soliciting opinions on the 2022 annual project application guidelines for 24 key special projects including the "14th Five-Year Plan" National Key R&D Plan "Coal Clean and Efficient Utilization Technology", with the "14th Five-Year Plan" as the "14th Five-Year Plan".
"National key research and development plan "Smart Sensor" key special project application guide in 2022 (draft for comments) as an example, for intelligent sensing basic and cutting-edge technologies (13), sensor sensitive components key technology (15), industry-oriented Intelligent sensors and systems (6), sensor research and development support platforms (2), and the "smart sensor" key project in 2022 "Revealing the Leaders" list task (1) five aspects, a total of 37 scientific research projects, for each The research content and assessment indicators of the research topic have made clear requirements
.

 

　　On March 11, the Shenzhen Municipal Bureau of Industry and Information Technology issued a notice on the public solicitation of opinions on "Several Measures for the Acceleration of the Development of the Smart Sensor Industry in Shenzhen" (Draft for Comments).
Production) production line construction, support measures for the stable operation of MEMS (pilot, mass production) production lines
.

 

　　There are many companies in China's sensor market, including Huagong Technology, Dali Technology, Weiltai, Goertek, AVIC, Hanwei Technology, AutoNavi Infrared and Senba Sensing
.
The state promotes the development of smart sensors and, to a certain extent, also gives these enterprises policy support, which effectively promotes the agglomeration of the sensor industry, promotes local employment, and drives economic growth
.

 

　　In the future, advances in various basic sciences will further promote the rapid evolution of sensor technology
.
Miniaturization will be the trend of sensor development
.
With the continuous development of the Internet of Things, AI, and big data, the human-computer interaction experience is expected to be further improved
