[ China Instrument Network Instrument R&D ] With the in-depth implementation of China's energy conservation and emission reduction work and the increasing attention of the people to environmental issues, environmental monitoring sensors are playing an increasingly important role in our daily production and life.
After nearly 9 years of research, the Institute of Semiconductors of the Chinese Academy of Sciences and the joint laboratory of Beijing Hangxing Network Technology Co., Ltd. have successfully developed a new generation of semiconductor laser gas sensor domestic chips, and have large-scale mass production conditions, which have been fabricated into lasers. .
In the future, the laser gas sensor designed and developed by Hangxing can be applied to low-range and full-range measurement. Its temperature adaptability can reach the industrial grade (-40°C～70°C) standard, and it is widely used in coal gas monitoring and underground pipe gallery gas. Perception, urban gas safety and fire protection, etc., to help the safety monitoring, early warning, and response measures of high-risk industries to be taken in a timely manner.
At present, the countries that master the production technology of laser methane gas detection chips are mainly Canada, the United States, Japan, Norway, etc. The large-scale mass production of methane laser gas sensor chips by Hangxing shares also means that domestically replaced imported chips will be realized.
With the increasing awareness of environmental protection and the importance of governments in the prevention and control of atmospheric pollution, it has created huge market opportunities for the application of gas sensors. In addition, with the rapid development of the Internet of Things, the application of gas sensors in the emerging smart home, wearable devices, intelligent mobile terminals and other fields has advanced by leaps and bounds, greatly expanding the application space, and the demand has also changed by orders of magnitude.
According to market research firm Yole Développement, the global gas sensor market will reach 920 million US dollars in 2021, with a compound annual growth rate of 7.3% in the next five years, of which environmental monitoring ranks third in all application areas.
As a leading company in the domestic gas sensor segment, Hanwei Technology has conducted trial production of laser gas sensors. Guangli Technology is a leading enterprise in the field of coal mine safety monitoring. Its laser methane sensor has been produced in small batches.
It is believed that with the successful development of the new generation of semiconductor laser gas sensor domestic chips, China will realize more in-depth independent innovation and development potential in many fields in the future, and will also strengthen the security warning aspect in the face of some unexpected situations. ability. This has an irreplaceable role for China's foothold in the international advanced science and technology field.
