Abstract

본 발명은 동잡음 제거를 위한 광전용적맥파(photo-plethysmogram : 이하 PPG) 검출용 센서모듈의 형태 및 방법에 관한 것으로 PPG 검출기로 측정되는 광혈류량 신호에서 움직임에 의한 동잡음을 제거시켜, 최종 데이터의 신뢰도를 높이는 것을 주 목적으로 한다. 본 발명은 한 지점에서 계측된 PPG 동잡음을 제거하기 위하여 2개의 센서가 서로 등지게 배치된 PPG 센서모듈 하나를 이용하여 한 지점의 PPG 측정을 하는데 사용하며, 이와 같은 한 단위의 센서 모듈 2개 이상을 어레이 형태와 매트릭스 형태로 배열하여 신체 표면의 여러 영역에서 PPG 측정시 동잡음을 제거하게 된다. 본 발명으로 PPG 측정시 동잡음을 효과적으로 제거하여 신뢰성있고 지속적인 PPG 신호 측정이 가능하고, 궁극적으로 심박수나 심박변동에 의한 스트레스 등 2차적인 생체정보를 해석해 낼 수 있게 된다.
