In the exhibition hall of the Hanwei Technology Group, Wu Chuanwei took a disc look back and forth, and more than 10,000 sensors were hidden on the wafer size of the rearview mirror. After four years of MEMS semiconductor sensor samples. On the way, in addition to the hope of the industry, Wu Chuanwei has the feelings that cannot be let go.

Various gases that exist all the time are a treasure in the eyes of Wu Chuanwei. He regards the "gas" as the target, practiced "detection" internal skills, and continuously sought breakthrough in the wave of sensor industry. He gave all things for all things. Sales."

From 2,000 yuan to two to thirty yuan

Domestic sensors fall to civilian prices

On August 23, the 2022 World Sensor Conference ended successfully in Zhengzhou. As the host of the conference, Hanwei Technology Group, four consecutive consecutive sessions presenting high -quality and efficient sensors and their testing schemes, Internet of Things solutions and its industry vertical applications, attracting many big coffees in the industry to stop.

Product introduction, application exchanges, Hanwei became the popular "star" at the scene.

"Through the gas sensor, the concentration of conventional gases is converted into a monitoring signal through physical or chemical methods." The dean Wu Chuanwei explained that the sensor and the chip can be used in mobile phones and headphones. It is widely used in life. "If natural gas is leaked, the gas sensor is like a human nose, which can be detected at the initial stage."

Wu Chuanwei is 40 years old. He studies electrochemistry in college. After graduation, his first job is in the battery industry. 11 years ago, he joined the Hanwei Technology Group and turned to the innovative research and development of gas sensing technology.

Behind the change, Wu Chuanwei has such feelings.

"Before 2005, there were no manufacturers in China to make electrochemical sensors. The electrochemical sensors we used were bought from abroad. A sensor may be one or two thousand yuan, or even thousands of people." After the company was put into production, the price of the entire industry chain was pulled down.

"When we do gas detection, we can reflect the changes in the current and voltage of the sensor by measuring the gas." Wu Chuanwei and the R & D team made many types of sensors according to different technical categories.

With the design of new technology and original circuit, Wu Chuanwei has a number of technologies through provincial appraisal and awards. Multiple products have obtained fire product type recognition and metering equipment manufacturing licenses. Successfully entered the international market.

18㎜ reduced to 1㎜

Four years of "grind" the world's leading third -generation sensor sample

In the exhibition hall of the Hanwei Technology Group, various detection "artifacts" are displayed, and the home gas alarm connected to the mobile phone can be perceived in real time. The car can detect the micro -amount of gas leakage below 60 kilometers per hour, which is a weapon for the pipeline inspection of the gas company.

The core of these devices is sensors.

Hanwei Technology Group started from tube semiconductor gas sensors and gradually developed plane semiconductor sensors. To expand the application scenario, the sensor must be miniaturized and must break through technically.

This is a "hard bone".

You know, in 2011, when the Hanwei technical team developed MEMS semiconductor sensors, there was no such technology in the country. It is difficult to find a qualified laboratory. Four years later, the sample was officially made.

"At that time, the miniaturization design was very high in the requirements of scientific researchers and experimental conditions. It gave me very great pressure. We also had to expose some strange technologies. While learning, we introduced talents and everyone came together. "In the end, the Hanwei technical team made the diameter of the sensor from 18 ㎜ to 1㎜, and made MEMS semiconductor sensors to achieve miniaturization and small power consumption, and the scope of applications was wider.

"Our third -generation MEMS semiconductor sensor has been upgraded to a wafer -type micro -hot plate. There are more than 10,000 sensors on this piece." Wu Chuanwei said with a large rear -view mirror -sized disc After three iterations of sensors, the products have their own advantages, so the "Third Life Tongtang" is sold. "

75% of the domestic market share

Small sensors are made into industry leaders

There are more than 200 types of mainstream gas sensors in the world, and Hanwei Technology Group can produce more than 100 types; the annual production capacity of gas sensors is more than 30 million, and the domestic market share is as high as 75%;

As of 2021, the company has obtained 671 national patents, and 42 products have been appraised through scientific and technological achievements;

Native

In 2014, Wu Chuanwei introduced the battery technology and use into sensor detection, and made a water -based environmentally friendly gas sensor. Even the electrolyte was pure water, and it also won the second prize of the scientific and technological progress of Zhengzhou City. New products have achieved a total sales income of more than 2 million yuan in the company.

"Make a sensor and two sensors. The laboratory test is fine, but hundreds of thousands of mass production, it is difficult to ensure that the qualification rate is high. This is difficult." In the past, the electrochemical sensor was Tibetan Tibetan In the "treasure" of the laboratory of universities and research institutes, the Hanwei Technology Group was the earliest product to productize it in the country. "Our team is a gas sensor, and now we are also one of the best in the country. It belongs to the leading enterprise. Our core and strengths are the control of crafts during mass production to ensure the qualification rate, stability, and consistency of the product."

In Hanwei Technology's laboratory, the sensors produced 10 years ago were like "baby" and were observed by Wu Chuanwei's studio research and development team every day.

"The test is normal and can judge and monitor gas leakage. In the end, the sensor can use 10, 8 years or 5 years. We have actual data support to judge its performance and life." Wu Chuanwei bluntly comes from innovation capabilities, the product advantage comes from innovation capabilities, At present, there are more than 700 company R & D personnel. In recent years, R & D investment accounted for about 7%of the operating income ratio.

Host or undertake national key projects, major special projects in Henan Province, the second prize of Henan Province Science and Technology Progress, 35 national authorized patents, and two national standards ... Many honors have made Wu Chuanwei a significant responsibility, based on the industry, based on the industry Judging that he was leading the team to start the development of a new generation of sensors.

In the era of interconnection of all things, the gas sensor industry welcomed the wind. Wu Chuanwei practiced the internal skills of "gas testing", and continued to seek breakthroughs in the tide of the sensor, so that the cold equipment of the cold was "wisdom" to give spirituality for all things.
