[ Focus on Chemical Machinery and Equipment Network ] Nowadays, with the continuous deepening of environmental governance and the rising upsurge of environmental protection, domestic and foreign sensor companies have entered the field of environmental protection one after another, and the environmental monitoring sensor market is just around the corner
.

Chemical machinery equipment network hotspots focus on chemical machinery equipment sensors

With the increase of society’s awareness of environmental protection, sensors are indispensable key components in the process of environmental protection, and the status of their related industries in China has been increasing year by year
.

1.
Sensor materials and device technology and its characteristics

From a technical point of view, sensors refer to basic functional devices with information collection functions, including photoelectric, infrared, force sensitive, biological and other sensors
.
The sensor material refers to small changes in sound, light, electric, magnetic, thermal and other sensitive signal response reflects the functional material, the structure and materials required for producing a sensor, including: a semiconductor, metal, composite materials and the like
.

Sensor technology and its industry have the characteristics of technology-intensive, multi-technology collaboration, strong industry penetration, high cross-border integration, and low industry concentration; sensor products have many varieties, small batches, complex structures, scattered technical indicators, and large parameter spans.
, High precision requirements, wide range of applications, etc.
; sensor materials and devices have consistency and stability, as well as technical fundamentals and high synergy requirements
.

In the field of sensor technology, due to factors such as the overall development level, technical strength, and talent accumulation, China has formed a "generation gap" with countries such as Europe and the United States.
China's sensor technology is particularly urgent to catch up
.

Second, the future development direction of sensor technology

With the development of a new generation of information technology, the field of environmental monitoring has put forward new requirements and challenges for sensor equipment
.
Specifically, the new generation of environmental monitoring equipment needs to develop in the following directions:

1.
Zero power consumption

　　In a huge IoT sensor node, it is unrealistic to replace the battery every few months
.
The "zero power consumption" sensor can completely shut down the matching circuit, communication and other systems at ordinary times, and it does not need to consume power to maintain sensitivity to external stimuli
.
When receiving the external change "event" (such as vehicle passing, harmful gas leakage, specific spectrum, etc.
), the back-end circuit etc.
are connected to realize true "zero power consumption" environmental monitoring
.

　　2.
Wireless on-demand connection

　　Another major energy consumption of IoT wireless sensor nodes comes from wireless communication
.
Therefore, the use of new materials and devices to achieve wireless on-demand connection, usually the entire communication system is completely shut down, and successfully awakened when needed, is an important direction for the development of wireless sensors in the future
.

　　3.
Multidimensional information integration

　　That is, the development can measure multiple parameters of a single application scenario at the same time, and process the collected multi-dimensional data through edge computing and other methods, and output results that are strongly related to the application scenario.
It has the characteristics of multi-sensor fusion and system integration.
The new type of sensor in order to realize the ability of a single sensor to perceive multi-dimensional information, realize the integration of calculation, storage and transmission at the edge of the sensing end, improve the adaptability to application scenarios and environments, and improve reliability
.

　　4.
Network protocol and integration

　　In the future, sensors need to be built on a unified material technology platform to form a collaborative design of the sensor, which will be processed at one time through a unified material platform
.
It can also be compatible with the existing CMOS process to form a single-chip integration of multiple sensors and multiple signal reading circuits with network protocol, which greatly improves the integration of sensors
.

　　5.
Sensors for special applications

　　Including physiological signal acquisition sensors for special environments, and sensors that need to be transparent, flexible, stretchable, bendable, and wearable for special applications
.

　　6.
Multi-sensing function sensor

　　Sensors have been perceived from single-dimensional physical quantities such as force, heat, sound, electricity, and magnetism, and expanded to new types of sensing functions for gas, liquid, infrared and other information.
In the future, there will be heat, pain, humidity, touch, etc.
that can affect human skin.
Perceptual sensors
.

　　7.
Intelligent

　　Integrate a variety of sensor functions with data processing, storage, two-way communication and other functions to fully or partially realize automatic sensor control, automatic detection, automatic analysis, automatic diagnosis and other functions
.
Another direction of intelligence is soft sensing technology, that is, the combination of smart sensors and artificial intelligence
.
