Experimental photoplethysmography (PPG) dataset used for the assessment and validation of the mathematical model of PPG signals reported in A. Lefieux, J. Daraize, F. Vergnet, M. Vidrascu, M. Willemet, A. Bendjoudi, D. Lombardi, M.A. Fernández, "Mathematical modeling of photoplethysmography: model assessment and validation", hal-05134478, 2025. The PPG and pulse pressure measurements of this dataset were collected by Withings SAS during an internal experimental campaign involving 20 volunteers. The data was anonymized before being shared for research purposes, so that this dataset involves only secondary anonymized PPG and pulse pressure data. See the README file for a complete description of the data and files.
