  Noncontact Detection of Vital Signs and Vibrations Using Micro - Radar



Time: 1:20pm, April 30 (Thursday)

Title: Noncontact Detection of Vital Signs and Vibrations Using Micro - Radar

Speaker: Prof. Jenshan Lin
     (Department of Electrical & Computer Engineering, University of Florida)

Place:Science Building III B1 SC001

This talk will introduce a portable micro-radar system that can detect human heartbeat and respiration or
mechanical vibrations from a distance away. This noncontact detection method has many potential
applications such as healthcare, veterinary medicine, biology, and industrial manufacturing. Through
understandings of its detection mechanism and advances in hardware and software, the once bulky Doppler
radar systems can be miniaturized while achieving the same or even better performance. I will describe
several micro-radar sensors demonstrated by my research group. These sensors are integrated in PCB
modules, CMOS chips, or System-in-Package. I will also introduce RF vibrometer using continuous-wave radar to
determine the displacement of vibration, based on nonlinear Doppler phase demodulation. Not only the vibration
frequency, but also the vibration displacement can be determined with reasonable accuracy without the need of
calibration (as long as the radar frequency is accurately set).

Jenshan Lin received the BS degree in Electrophysics from National Chiao Tung University in 1987, and MS
and PhD degree in Electrical Engineering from the University of California at Los Angeles (UCLA) in 1991 and
1994. From 1994 to 2003, he worked for the AT&T/Lucent Bell Labs and its spin-off Agere Systems in New
Jersey. In July 2003, he joined University of Florida, where he is now a Professor. His research interests
include sensors and biomedical applications of microwave and millimeter-wave technologies, wireless energy
transfer, RF system-on-chip integration, and integrated antennas. Dr. Lin has authored or co-authored more
than 240 technical publications in refereed journals and conference proceedings, and holds 14 US patents. He
has graduated 19 PhD students since 2006.

Dr. Lin is a Fellow of IEEE. He served as an elected IEEE Microwave Theory and Techniques Society (MTT-S)
Administrative Committee member from 2006 to 2011, with the last two years serving as the Chair of
Technical Coordinating Committee, overseeing the 26 technical committees of the society. He was an
Associate Editor for the IEEE Transactions on Microwave Theory and Techniques 2006-2010, and is now the
Transactions' Editor-in-Chief. He has been serving on several conference steering committees and technical
program committees. He was the General Chair of 2008 IEEE RFIC Symposium and the Technical Program Co-
Chair of the same conference in 2006 and 2007. He was the General Co-Chair of 2012 Asia-Pacific Microwave
Conference (APMC). He received 1994 UCLA Outstanding Ph.D. Award, 1997 ETA KAPPA NU Outstanding
Young Electrical Engineer Honorable Mention Award, and 2007 IEEE MTT-S N. Walter Cox Award.
