Bottom Line: The protocol involved 16 healthy subjects and was designed to test the features of OEPS, with emphasis on the effective reduction of motion artefacts through the utilization of a 3MA as a movement reference.The results show significant agreement between the heart rates from the reference measurements and the recovered signals.The outcome of the present work incites the prospects of OEPS on physiological monitoring during physical activities.

ABSTRACT
This paper presents a comparative study in physiological monitoring between a wearable opto-electronic patch sensor (OEPS) comprising a three-axis Microelectromechanical systems (MEMs) accelerometer (3MA) and commercial devices. The study aims to effectively capture critical physiological parameters, for instance, oxygen saturation, heart rate, respiration rate and heart rate variability, as extracted from the pulsatile waveforms captured by OEPS against motion artefacts when using the commercial probe. The protocol involved 16 healthy subjects and was designed to test the features of OEPS, with emphasis on the effective reduction of motion artefacts through the utilization of a 3MA as a movement reference. The results show significant agreement between the heart rates from the reference measurements and the recovered signals. Significance of standard deviation and error of mean yield values of 2.27 and 0.65 beats per minute, respectively; and a high correlation (0.97) between the results of the commercial sensor and OEPS. T, Wilcoxon and Bland-Altman with 95% limit of agreement tests were also applied in the comparison of heart rates extracted from these sensors, yielding a mean difference (MD: 0.08). The outcome of the present work incites the prospects of OEPS on physiological monitoring during physical activities.

biosensors-05-00288-f014: (a) Correlation; and (b) difference analysis of the HR data.

Mentions: Additionally, the correlation and difference disruption were performed by using Wilcoxon test and it was found that the data is highly correlated, with a correlation coefficient r = 0.97 between the data, as shown in Figure 14a. In addition, the mean of differences was found to be 0.08, indicating that there is no significant difference between the data from OEPS and from the commercial monitor.
