Lehigh CPN Seminar Series - Summer 2014

Non-Contact Cardiac Activity Monitoring using Pulsed Laser Vibrometer

Monday, August 11th  |  4:00-5:30 p.m.  |  101 STEPS Building

Dr. Venkataraman Swaminathan
Chief, Acoustics and Networked Sensors Division
U.S. Army Armament Research, Development and Engineering Center

Abstract:
In his talk, Dr. Swaminathan will describe a highly sensitive pulsed laser vibrometer and its applications. In particular, he will demonstrate its application in the detection of detailed human cardiac mechanical activity in a remote, non-contacting, and non-ionizing manner. The highly sensitive pulsed laser vibrometer allows the detection of the temporally-phased mechanical events occurring in individual cardiac cycles even from the surface of clothing-covered extremities of the subjects. Fine structures of the detected cardiac traces are identified with their meanings assigned and corroborated using accelerometer and electrocardiogram measurements obtained concurrently with the pulsed laser vibrometer studies.

Bio:
Dr. V. ("Swami") Swaminathan is currently Chief of the Acoustics and Networked Sensors Division of the U.S. Army Armament Research, Development and Engineering Center in Picatinny, NJ. In this role, he sets the vision and the direction in advanced technology development in the areas of acoustic and other passive sensors for hostile fire defeat, IED and explosives detection.

Dr. Swaminathan obtained his doctorate in Materials Science from the University of Southern California in 1975. He worked at Bell Laboratories for 21 years and later at Agere and TriQuint Semiconductors for 3 years. During his tenure at Bell Labs, he worked on semiconductor lasers and systems for fiber optic communication and held senior management positions at Lucent, Agere and TriQuint. From 2004-2006, he was chief of the IR Materials and Devices Branch at the U.S. Army Research Laboratory, where his team was responsible for conducting research in current and future needs of the U.S. Army in infrared emitters and detectors.

Swaminathan is a Fellow of IEEE and of the American Electrochemical Society. He has authored/co-authored 148 publications in peer-reviewed journals and has received 7 patents. He is the co-author of the book Materials Aspects of GaAs and InP Based Structures, and has served as editor of four other books. Dr. Swaminathan has served on the editorial board of Review of Scientific Instruments from 2007-2010 and as a guest editor for the Special Issue on the IEEE Transactions on Nanotechnology, September 2010. He also served as an Associate Editor of IEEE Transactions on Nanotechnology.
