As thin as a cicada wing, business card size... This is the University of Electronic Science and Technology "core electronic materials and devices" collaborative innovation center developed a called "high permeability magnetic substrate" ceramic material. This material has been used in Huawei, Meizu, ZTE, OPPO and other domestic mobile phones in batches to ensure the near field communication (NFC) antenna signal transmission of mobile phones.

Because of the research and development and industrial application of the material, Deng Longjiang, professor of the University of Electronic Science and Technology of China and director of the National Engineering Technology Research Center for Electromagnetic Radiation Control Materials, presided over the project "Key Technologies and Industrialization of High Permeability Magnetic Substrates" recently won the second prize for national scientific and technological progress in 2018.

"High permeability magnetic substrate is a new type of electronic information functional material that has developed rapidly in the world in recent years." According to Deng Longjiang, the material is widely used in military and civilian fields such as near-field communication, wireless charging, and anti-electromagnetic interference. The information industry, especially the development of wearable flexible electronic technology, has an important role in promoting.

It is reported that through more than ten years of efforts, the National Electromagnetic Radiation Control Materials Engineering Technology Research Center of the University of Electronic Science and Technology of China has invented a magnetic substrate material formula system with high permeability and low loss; it has established a fully soluble water system tape casting process, which is safe and environmentally friendly. It also reduces production costs; it has mastered the integrated design technology of magnetic substrate materials, formed independent intellectual property rights, and broke the monopoly of foreign technology.

Deng Longjiang revealed that the results of the project have been industrialized, and the current one-day output can meet the needs of 600000 mobile phones. Relevant results have been adopted by well-known domestic and foreign companies such as Meizu, Huawei, Amfino, and the 14th Research Institute of CLP. The products involved cover hundreds of electronic devices in 6 categories such as smartphones and wearable devices, and are sold to the United States and Europe., Japan and other dozens of countries and regions.

"The application prospect of high permeability magnetic substrate is very broad, which can be widely used in wireless charging, access control, UnionPay payment, bus payment and other fields, bringing more convenience to people's life." Deng Longjiang said that as the basic material of a new type of sensing system, the material is expected to be widely used in the Internet of things, artificial intelligence and other fields in the future.

It is understood that the National Electromagnetic Radiation Control Materials Engineering Technology Research Center of the University of Electronic Science and Technology of China has in-depth cooperation with domestic aerospace, aviation, electronics, ships and other advantageous units to promote and establish a "collaborative innovation center" with electronic information as the core and multi-advantageous units. ", forming a one-stop scientific and technological innovation model of" production, education, research and application. In recent years, the University of Electronic Science and Technology has radiated new technologies to the civilian field, which not only creates significant economic benefits, but also provides important support for leading the transformation and upgrading of the regional economy.
