合作导师简介:

Chengkuo Lee received the M.S. degree in materials science and engineering from National TsingHua University, Hsinchu, Taiwan, in 1991, the M.S. degree in industrial and system engineering from Rutgers University, New Brunswick, NJ, USA, in 1993, and the Ph.D. degree in precision engineering from The University of Tokyo, Tokyo, Japan, in 1996. He was a Foreign Researcher with the Nanometerscale Manufacturing Science Laboratory of the Research Center for Advanced Science and Technology, The University of Tokyo, from 1993 to 1996. He was with the Mechanical Engineering Laboratory, AIST, MITI of Japan, as a JST Research Fellow, in 1996. Thereafter, he became a Senior Research Staff Member of the Microsystems Laboratory, Industrial Technology Research Institute, Hsinchu. In 1997, he joined Metrodyne Microsystem Corporation, Hsinchu, and established the MEMS Device Division and the first micromachining fab for commercial purposes in Taiwan. He was the Manager of the MEMS Device Division between 1997 and 2000. He was an Adjunct Assistant Professor with the Electro-Physics Department, National Chiao Tung University, Hsinchu, in 1998, and an Adjunct Assistant Professor with the Institute of Precision Engineering, National Chung Hsing University, Taichung, Taiwan, from 2001 to 2005. In 2001, he cofounded Asia Pacific Microsystems, Inc., Hsinchu, where he first became Vice President of Research and Development, before becoming Vice President of the Optical Communication Business Unit and Special Assistant to the Chief Executive Officer in charge of international business and technical marketing for the MEMS foundry service. He was a Senior Member of the Technical Staff at the Institute of Microelectronics, A*STAR, Singapore, from 2006 to 2009. Currently, he is an Associate Professor with the Department of Electrical and Computer Engineering, National University of Singapore, Singapore. He is the coauthor of Advanced MEMS Packaging (McGraw-Hill, 2010). He has contributed to more than 190 international conference papers and extended abstracts and 130 peer-reviewed international journal articles in the fields of sensors, actuators, energy harvesting, MEMS, NEMS, nanophotonics, and nanotechnology. He holds nine U.S. patents.

   随着技术的进步，微型传感器和无线收发器的功耗越来越低，其组成的无线传感器网络将广泛应用于军事、智能交通、环境监控、医疗卫生等多个重要领域。然而，现有的化学电池仅有有限的寿命，如何为这些器件提供长时间的供能是一个普遍存在的问题。从环境中捕获能量是一个可能的解决方法。

    在此报告中，将简单介绍几种振动能量收集和流体能量收集的方案，并提出一种利用流致振动的微型压电能量收集装置。
