CORRELATION ANALYSIS OF PHOTOPLETHYSMOGRAM SIGNALS OF PULSATION

摘要

This paper characterizes the important features of photoplethysmogram (PPG) signals to advance the development of sensor units that can monitor vital data and/or prevent drunk drivers from driving. This paper discusses the correlation of various PPG signal spectra with a time lag. We demonstrate how these analyses, based on Lissajous curves and chaotic analysis, are applicable to detection of alcohol intake.
