UWB Radar Sensors for Elderly Health Monitoring

Professor Hanyang University South Korea


ABSTRACT: Health monitoring technologies for elderly people based on ultra-wideband (UWB) radar sensors have attracted a great amount of attention lately. Unlike conventional pressure and motion sensors or wearable sensors, the radar sensor enables health monitoring in a wireless and noncontact fashion so that it can provide great convenience to elderly people for daily use at home.

This talk is intended to introduce basic concepts and potential applications of the UWB radar sensors for elderly health monitoring. Specifically, the radar techniques related to fall detection, vital sign monitoring, arrhythmia detection, and sleep monitoring will be addressed. The signal processing and radar computing algorithms involved in each of the cases will also be discussed. Clinical experiments conducted at Hanyang University Medical Center will be presented in order to demonstrate the usefulness of the UWB radar sensors by comparing the radar performances with those of medical equipments.


SHORT BIOGRAPHY: Sung Ho Cho received the Ph.D. degree in Electrical and Computer Engineering from the University of Utah, Salt Lake City, USA, in 1989. From 1989 to 1992, he was with Electronics and Telecommunications Research Institute (ETRI) of South Korea as a senior member of technical staff for three years. He then joined the Department of Electronic Engineering in Hanyang University, Seoul, South Korea, in 1992, where he is currently a full professor. He served as an Associate Dean and later Dean of the College of Engineering in Hanyang University from 2013 to 2017.

Professor Cho has been actively engaged in numerous government and industry research projects related to applied signal processing, context-aware computing, radar applications, and wireless communications. In 2008, he founded Samsung-Hanyang Joint Research Center in Hanyang University and served as a Director for 5 years. During 2011-2013, he served National Science and Technology Commission of Korea as a member of Board of Intellectual Properties. Since 2017, He has been a member of Expert Group in Technology Level Evaluation appointed by Ministry of Science and ICT in Korea.

Based on his knowledge and experiences on IR-UWB radar sensors, he founded a start-up company, Xandar Kardian Inc. (Http://xandarkardian.com) in USA in 2018 in order to deliver smart radar sensor solutions in various applications of non-contact health monitoring, people counting, safety/security, automotive, gesture recognition, and so on. He has been with the company as CTO ever since.
