Abstract
Photoplethysmography (PPG) sensing takes advantage of hemoglobins’ absorbent qualities to visible and infrared (IR) light. Consisting of a light source and a photo-detector, light is emitted into the skin and the intensity of light transmitted into the photo-detector is inversely proportional to the volume of blood in the vascular bed of the measurement site [1], [2]
