Advanced Materials & Sensing Technology Lab

Advanced   Materials & Sensing Technology Lab was established on October 2015 in   Room 105 and 107, Information Building, China University of Geosciences,   Wuhan. It is affiliated to Hubei key Laboratory of Advanced Control and   Intelligent Automation for Complex Systems, School of Automation, China   University of Geosciences, Wuhan. At present, there are five teachers in the   laboratory, including 1 professor and 4 associate professors. Among them,   Professor Dong Kaifeng was selected as the Hubei Provincial Hundred Young   People (2018), Hubei Province Chutian Scholars (2016), and Cradle Program   Winners of China University of Geosciences, Wuhan. Till now, the laboratory   has graduated 13 students and 27 graduate students are studying in it now,   which includes 1 doctoral student, 10 academic masters, 15 professional   masters, and 1 international student. The laboratory focuses on the   collection, processing, transmission and visualization of weak signals. The   main research directions are magnetic materials and sensors, single crystal   piezoelectric materials for ferroelectric relaxation, acceleration sensors,   and functional devices for new nano-electronic optoelectronics. Research on   the sensitive mechanism and preparation technology of geomagnetic, optical   waveguide and piezoelectric sensing technologies have been carried out. It   intends to sensing technology with high-precision, high-sensitivity,   miniaturization for geological environment monitoring, and make a foundation   for the geological environment monitoring improvement.

Research   Activities

The   research currently carried out by the laboratory is mainly divided into two   categories: Pioneering scientific research and engineering projects. The   groundbreaking scientific research includes a project founded by the National   Natural Science Foundation of China which named as Noise’s Generative   Mechanism and Optimization Design of the thin-film Geomagnetic Sensor Based   on Giant Magneto-impedance Effect, hosted by Jin Fang. Besides, the two   Natural Science Foundation Youth Projects of Preparation, characterization   and mechanism of crystalline oxide doping induced columnar FePt fims with large   perpendicular anisotropy on new TiN-X intermediate layer, Theoretical and   experimental research of integrated optical geophone based on   silicon-on-Insulator microring resonator, hosted by Dong Kaifeng and Mo   Wenqin, respectively.

The   engineering research projects mainly include: "weak geomagnetic signal   detection based on GMI magnetic sensor" completed by Jin Fang;   "system design for residential home based on ZigBee and WIFI"   completed by Dong Kaifeng; "Equipment Development foe Leak Detection   " and "Device and APP Development for Small XRF Analysis "   completed by Song Junlei; and "Fiber Grating Sensing and Photoelectric   Inspection" realized by Mo Wenqin.

In   addition, active and extensive academic exchange activities at home and   abroad have carried out in the laboratory. All teachers have more than one   year experience of foreign study and research. Recent years, the laboratory   has repeatedly invited internationally renowned experts to conduct exchange   visits, send teachers to participate in international academic conferences   3-4 times a year. And one exchange student is abroad now.

Major   Achievements

The   laboratory currently has a total of 10 scientific research projects,   including 2 national projects, 1 provincial and ministerial projects, 1   provincial talent project, 5 school projects, and 1 horizontal project. 30   papers have been published on academic journals at home and abroad, including   21 papers and above at T4 level, 9 papers at T2 level and 8 papers at T3   level. Moreover, 17 national invention patents has been declared, more than   30 software copyrights were obtained. 13 items for trained graduate students   has been obtained.
