Abstract
<p>Photoplethysmography is a simple measurement method using only a light source and a photodetector. Therefore, it is widely used in many wearable devices such as smartwatch. However, this method has the problem of being strongly influenced by motion artifacts, and this influence needs to be removed for daily measurements. We focused on the distance between the light source (LED) and the photodetector (PD). In this study, we developed a sensor that can simultaneously measure four pulse waves with different PD-LED distances. Using this sensor, we measured the pulse wave with added motion artifacts by having the subject shake the measurement site. The obtained signal was divided into the pulse wave component (1-2 Hz) and the noise component (5- Hz), and the SN ratio was calculated. This result demonstrated the effect of motion artifacts due to PD-LED distance in the photoplethysmography.</p>
