Photoplethysmographic (PPG) signals contain body motion artifacts. In order to use PPG signals for daily basis pulse rate measuring, we must cancel body motion artifacts from PPG signals. In our study, we made a prototype board for PPG measuring. This board also contains 3-axial accelerometer for body motion measuring. This board was affixed to the upper arm to measure signals. After measurement, pulse rate was detected by using offline signal processing to reduce body motion artifacts, where signals from 3-axial accelerometer were used. After processing, we succeed in obtaining more accurate pulse rates.
