Using Optical IoT Sensing for Detrended Fluctuation Analysis of Skin Blood Pulsation during Visual Stimulation Task

This paper considers optical IoT sensing for the analysis of cardiovascular state. It is used for skin blood pulsation, i.e. photoplethysmography (PPG) signals acquisition and analysis using DFA (detrended fluctuation analysis) approach. Visual stimulus has been performed during the acquisition process. The results showed that DFA based spectra can be useful in further monitoring of the PPG signals. Analysis was performed using signals recorded from eight young volunteers.
