Exploring Near- and Far-Field Effects in Photoplethysmography Signals Across Different Source–Detector Distances

Exploring Near- and Far-Field Effects in Photoplethysmography Signals Across Different Source–Detector Distances

Photoplethysmography is a widely used optical technique to extract physiological information non-invasively. Despite its large use and adoption, multiple factors influence the signal shape and quality, including the instrumentation used. This work analyzes the variability of the DC component of the...
