RESUME

Associate Professor Bao Haifei received his BS degree in Semiconductor Physics and device from Liaoning University in 1991, MS degree in National lab of Integrated Optics from Jilin University in 1994, and his PhD in Physics and Electronics from Harbin Institute of Technology in 2000. In 2001 to 2002, He was a visiting scholar in the department of Mechanics in Hongkong University of Science and Technology. From 2000, he has been with the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences.

For many years, he mainly focuses on the characterization and measurement of MEMS surfaces and devices. For example, research of micro/nano friction was performed on Si surface and polymer surface based on Atomic force microscopy(AFM). Information storage on the PMMA film was finished with a heated cantilever/tip in AFM. A micro/nano mechanical measurement system and prototype with hardware and software was developed in AFM. Much research work was given to the design and shock and vibration measurement of accelerometer, and several measurement methods related to the characterization of accelerometer were proposed. He published more than 30 papers, and applies more than 5 patents. In 2007, He presented his oral reports on the conference of  Transducers’07 in France.
