Use of complex EMD generated noise reference for adaptive reduction of motion artifacts from PPG signals
TL;DR: The physical origins of PPG signals are explored and complex empirical mode decomposition (CEMD) adaptive filter is proposed and the robustness and efficacy of method are proved in accurate and reliable estimation of SpO2.

Extraction of respiratory activity from PPG and BP signals using Principal Component Analysis
TL;DR: In this paper, the respiratory induced variations (RIV) of PPG and BP signals are described by coefficients of computed principal components, and Singular value ratio (SVR) trend is used to find the periodicity, which is one of the crucial parameters in forming the data sets for PCA.

A Multi-Modal Sensor for a Bed-Integrated Unobtrusive Vital Signs Sensing Array
Xinchi Yu,Wilko Neu,Pascal Vetter,Leo Cornelius Bollheimer,Steffen Leonhardt,Daniel Teichmann,Christoph Hoog Antink +6 more
TL;DR: A novel unobtrusive multi-modal sensor for monitoring of physiological parameters featuring capacitive electrocardiogram (cECG), reflective photoplethysmogram (rPPG), and magnetic induction monitoring (MI) in a single sensor is presented.
On photoplethysmography artifact reduction and applications
TL;DR: In-vitro measurements are required to determine the true potential of the use of sensor displacement as a means to reduce motion artifacts in PPG signals, which have been obtained using the in- vitro setup.

Study of the relationship between Pulse Photopletismography amplitude decrease events and sleep apneas in children
TL;DR: An association between apneic events and DAP events is shown, which indicates that D AP events provide useful information in sleep research and PPG signals might be useful in the diagnosis of OSAS.
