Title: An Artificial Olfaction System – A Portable Electronic Nose and Applications
Speaker: Prof. Kea-Tiong Tang, National Tsing Hua University
Host: Prof. Guoxing Wang
Place: School of Microelectronics, Room 401
Time: June 25th, 10:15-11:00 am
ABSTRACT
Electronic nose (E-Nose) systems are still bulky in size, limiting its feasibility for portable applications. A portable E-Nose system has been designed, fabricated, and tested. Based on conducting polymer and surface acoustic wave (SAW) sensor arrays, this artificial olfaction system detects and classifies odors by recognizing their patterns. In this talk, biologic olfaction background will be given first, following by the background of the E-Nose. The portable E-Nose system will be introduced, and its applications for fish freshness detection and environmental monitoring sensor node will be discussed.
BIOGRAPHY
Kea-Tiong Tang received the B.S. degree in electrical engineering from National Taiwan University, Taipei, Taiwan in 1996, and received the M.S. and Ph.D. degrees in electrical engineering from California Institute of Technology, Pasadena, CA, USA, in 1998 and 2001, respectively.
During 2001–2006, he was a Senior Electrical Engineer with Second Sight Medical Products, Inc., Sylmar, CA, USA. He designed mixed signal ASIC for retina prosthetic device. In 2006, he joined the Electrical Engineering Faculty at National Tsing Hua University, Hsinchu, Taiwan, and is currently an Assistant Professor. His research interests include bio/chemical sensing system, analog and mixed signal IC design, neuromorphic SoC design, and biomedical SoC design.
Dr. Tang is a member of IEEE solid state circuit society (SSCS), circuits and systems society (CAS), and Engineering in medicine and biology society (EMBS). He is also TPC member of IEEE Life Science Systems and Applications (LiSSA).
