Magnetic Sensing Technology's "Black Technology" in Daily Life

For most people, "magnetism" seems to be an unpredictable technology. Whether it is semiconductor technology, MEMS technology, non-silicon MEMS technology... These professional physical terms are even more inscrutable to make it difficult for ordinary people to understand.

However, in the Huaming High-tech Zone in Dongli District, Tianjin, there is such a team, and every day, they are concentrating on this “black technology”, in order to make such high-end technology more suitable for the lives of ordinary people. Not long ago, at the just-concluded "The 5th China Innovation and Entrepreneurship Competition for the People's Republic of China", this team from the North University of Science and Technology Intelligent Equipment Industry Technology Research Institute led by Dr. Zhang Chao was based on a The "Magnetic Sensitive" high-tech application project for high-sensitivity magnetic-sensitive amorphous materials device applications won the first prize of the team group project.

Zhang Chao, the uncommon behind this ordinary name, makes this "post-80s" young dean become the main force of technological innovation, especially the "technology + model" innovation, and also injected a new vitality for "Tianjin Zhizao" .

This young "post-80s" dean is not ordinary, he is always "thinking" magnetic sensing technology, in his words, in the high-speed rail, a vehicle that frequently uses magnetic sensing technology, he "has more ideas" . "Maybe the sensor sounds more abstract, but it is indeed the basis of intelligence." Zhang Chao said that the sensor is like a smart brain, making decisions through a series of data, which is the basis of smart life and smart city in the future.

"Like the displacement of the car, the position movement of the high-speed rail aircraft, and the tilt angle monitoring of the new building, it is inseparable from the magnetic sensing technology." Zhang Chao cited an example, the magnetic sensor chip has been widely used in medical testing. . "Like some of the current "orbital navigation" during orthopedic surgery, because of the introduction of magnetic sensing technology, doctors can find the lesions more accurately and quickly, and implement treatment. Now some of the early diseases can be diagnosed by magnetic sensing technology. With higher accuracy, better repeatability and faster detection, it can be used for early and reliable diagnosis of various diseases such as heart disease, acute infectious diseases and malignant tumors."

At present, the magnetic sensing technology has been rapidly transferred from the past high-tech and military fields to the traditional basic industrial transformation, large-scale engineering system supporting, automotive electronic supporting, home appliance control system, medical and health, health care, environmental monitoring and management, etc. each field.

For his own profession, Zhang Chao also shows the uniqueness of the "post-80s" - as long as it is a topic of interest, one mouth can't stop. This is mainly because, for so many years, he has been working in the front line of research and development and technology management. Two years ago, after the selection of the Huaming High-tech Zone by the Institute of Intelligent Equipment Industry and Technology of the North University of Science and Technology, Zhang Chao, the leader of the team and a technical management expert, worked with the team on sensor chip design and sensor development. Core competence building in manufacturing, information system integration, and intelligent equipment will create a “brain” for smart cities in the future. Zhang Chao said that he and his team are very optimistic about the market prospects of magnetic sensing technology and intelligent equipment technology, and also see the future development opportunities of Tianjin city in the high-end intelligent industry, and this is their final choice to settle in Huaming. An important reason for the high-tech zone.
