Comparison of reflective PPG signals in a porcine skin phantom, a wearable device prototype, and Monte Carlo simulations
Abstract
We obtain and compare reflective Photoplethysmogram (PPG) measurements of a porcine skin phantom and a wearable device prototype with Monte Carlo simulations and analyse the received signal. In particular, we investigate typical PPG wavelengths at 520, 637 and 940nm and sourcedetector distances between 1.5 and 8.0 mm. We detail the phantom’s optical parameters, the wearable device design, and the simulation setup. Monte Carlo simulations were using layer-based and voxel-based structures. Pattern of the detected photon weights per wavelength and source-detector distance d showed comparable trends. PPG signal, differential pathlength factor (DPF), mean maximum penetration depth, and DC level showed dependencies on the source-detector distance d for all wavelengths.
