Abstract

A photoplethysmography (PPG) device, which filters the dc signal without distorting the pulse shape, was developed. Measurements were performed on the finger, for hand at heart level, below and above it. The PPG signal was highest above heart level, and lowest below heart level. It seems that the compliance and the resistance of the blood vessels influence the PPG curve.
