The well-known Prof. Omar Elmazria from Nancy University paid a visit to the Institute of Acoustics, Chinese Academy of Sciences at the invitation of Prof. WANG Wen during Aug 19-20, 2011. He delivered a report titled "Wireless and batteryless SAW sensors, a promising solution for harsh environments"on Aug 19.

Prof. Elmazria started his report with the history of surface acoustic wave devices, then he depicted that it performs well at the frequency space and low-cost mass production. He further introduced the research progress about surface acoustic wave devices being used in the sensor field around the world as well as recently hot research topics.

Prof. Elmazria got his doctor degree from the University of Metz in 1996. In 2003 he became professor in the school of Electronic and communication systems in Nancy University I in France. Now he is in charge of the Microsystems and Nanosystems Research Group in Institute Jean Lamour. His main field includes MEMS thin film, diamond, AlN and ZnO materials layered study of high-frequency resonator filter; SAW sensor applications, micro-fluidic systems and wireless sensor. He has published over 100 papers on international conferences and journals as a senior expert of many international academic organizations. He has been honored the title of "Institut Universitair de France" by French Ministry of Higher Education.
