Driver's health management system using nanosecond pulse near-field sensing technology

Abstract

Long-term and continuous non-invasive driver's health monitoring has shown that it is the most important to measure driver's fatigue level and personal health status. Currently, there are many preferable methods, including ECG, EEG and EOG, to get the physiological parameters of driver. However, the size of the machine is large and the operation of monitors is difficult. The measurement procedure is limited by long-term, continuous measurement and also easy to cause discomfort. To improve these issues, the noncontact and non-pressurized measuring method will become an important innovation improvement. This paper presents a driver's health management system using noncontact physical sensor technology. The system contains three portions: (a) nanosecond pulse near-field sensing (NPNS) radar system, (b) physiological signal processing, and (c) controller area network (CAN) system. The experimental results show that the NPNS radar sensor can be applied to detect driver's health status and combined with car system for driving safety and health management.
