合作導(dǎo)師簡介:

Chengkuo Lee received the M.S. degree in materials science andengineering from National TsingHua University, Hsinchu, Taiwan, in 1991, theM.S. degree in industrial and system engineering from Rutgers University, NewBrunswick, NJ, USA, in 1993, and the Ph.D. degree in precision engineering fromThe University of Tokyo, Tokyo, Japan, in 1996. He was a Foreign Researcherwith the Nanometerscale Manufacturing Science Laboratory of the Research Centerfor Advanced Science and Technology, The University of Tokyo, from 1993 to1996. He was with the Mechanical Engineering Laboratory, AIST, MITI of Japan,as a JST Research Fellow, in 1996. Thereafter, he became a Senior ResearchStaff Member of the Microsystems Laboratory, Industrial Technology Research Institute,Hsinchu. In 1997, he joined Metrodyne Microsystem Corporation, Hsinchu, andestablished the MEMS Device Division and the first micromachining fab forcommercial purposes in Taiwan. He was the Manager of the MEMS Device Divisionbetween 1997 and 2000. He was an Adjunct Assistant Professor with theElectro-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 becameVice President of Research and Development, before becoming Vice President ofthe Optical Communication Business Unit and Special Assistant to the ChiefExecutive Officer in charge of international business and technical marketingfor the MEMS foundry service. He was a Senior Member of the Technical Staff atthe Institute of Microelectronics, A*STAR, Singapore, from 2006 to 2009.Currently, he is an Associate Professor with the Department of Electrical andComputer Engineering, National University of Singapore, Singapore. He is thecoauthor of Advanced MEMS Packaging (McGraw-Hill, 2010). He hascontributed to more than 190 international conference papers and extendedabstracts and 130 peer-reviewed international journal articles in the fields ofsensors, actuators, energy harvesting, MEMS, NEMS, nanophotonics, andnanotechnology. He holds nine U.S. patents.

報告簡介：

隨著技術(shù)的進步，微型傳感器和無線收發(fā)器的功耗越來越低，其組成的無線傳感器網(wǎng)絡(luò)將廣泛應(yīng)用于軍事、智能交通、環(huán)境監(jiān)控、醫(yī)療衛(wèi)生等多個重要領(lǐng)域。然而，現(xiàn)有的化學(xué)電池僅有有限的壽命，如何為這些器件提供長時間的供能是一個普遍存在的問題。從環(huán)境中捕獲能量是一個可能的解決方法。

在此報告中，將簡單介紹幾種振動能量收集和流體能量收集的方案，并提出一種利用流致振動的微型壓電能量收集裝置。
