REFLECTANCE METHOD FOR A WEARABLE PHOTOPLETHYSMOGRAPHIC SENSOR – EXPERIMENTAL EVALUATION
Journal Title: The Polish Journal of Aviation Medicine, Bioengineering and Psychology - Year 2016, Vol 22, Issue 1
Abstract
Introduction: The article presents the design and testing results of a photoplethysmographic signal sensor intended for use in everyday activities. Methods: The design of the sensor involved a commercial DCM03 sensor based on the reflectance method and a fully integrated analog, front-end AFE4490. Determination of the photoplethysmographic signal and calculation of heart rate was based on appropriate data processing algorithms including digital filters, signal segmentation, moving average and variable baseline. Results: Measurements were carried out in different sensor placement locations as well as during specific body motions. Detailed analysis of the recorded signal was performed using the proposed processing methods and the fast Fourier transform technique. Discussion and Conclusion: Based on our results, it is possible to measure HR values and determine the photoplethysmographic curve under dynamic conditions. On the other hand measurement of blood oxygen saturation is subject to significant limitations.
