Dr. Chen-Kuei Chung received his B.E. and Ph.D. in Materials Science and Engineering from National Tsing Hua University, Taiwan, in 1989 and 1994, respectively. From 1994 to 2002, he worked at the Industrial Technology Research Institute for further technology research and development, including the process development and integration of MEMS technologies and key components such as inkjet printheads, IR sensor arrays, and biochips. He joined the Department of Mechanical Engineering, National Cheng Kung University (ME/NCKU), in 2002. He was promoted to Associate Professor in 2005 and then to full Professor in 2009, as well as taking the duty of Associate Head in 2017. He is a life member of several academic societies including the Taiwan Vacuum Society (TVS), Taiwan Association for Coating and Thin Film Technology (TACT), and Chinese Society of Mechanical Engineering, Taiwan (CSME). He was awarded as a 2018 Distinguished Engineering Professor of CSME, Taiwan. Dr. Chung’s research interests are micro-nano material science and engineering; the fabrication, characterization, and process integration of MEMS/NEMS devices for sensor, actuator, and LIGA applications, especially in in the advanced hybrid pulse anodization of AAO, characterization, SERS, and application; laser processing; polymer molding and application; mechanical energy harvesting from unique microneedle-triboelectric nanogenerators (TENGs).
