Abstract:

The ubiquity of smart wristwatches and advancements in optical sensing technologies have enabled noninvasive and continuous monitoring of vital signs such as pulse and blood oxygen saturation (SpO2) for sports and health monitoring. Pulse measurement from photoplethysmogram (PPG) signals is the most common application in this domain. However, during movement (e.g., walking and running), the PPG signal is altered, and pulse rate cannot be measured by conventional detection methods since the pulse frequency is highly suppressed. Although successful methods such as SPECMAR, TROIKA and JOSS have been proposed by others, which convert the PPG signal into a discrete spectral domain to distinguish between pulse and motioninduced frequencies, since the behavior of the methods vary according to the nature of the motion artifacts, significant errors may occur in measured heart rate. In this study, in order to increase the accuracy and robustness of pulse measurement, a combination of domain conversion techniques used by SPECMAR, TROIKA and JOSS methods is proposed along with pre and post processing operations. In order to validate the proposed method experimentally, 8 sessions of PPG data synchronized with accelerometer were collected by using the reference design wristwatch of Maxim Integrated. Polar ECG chest band was used as a reference. The method we recommend has 4.19 average absolute bpm error and is more robust than the previous methods.
