Abstract

In this paper, we propose a sleep efficiency measurement algorithm based on IR-UWB radar sensor in distance. Among the vital signs which can be measured by the IR-UWB radar sensor such as breathing rate, heartbeat rate, and movement, we analyzed correlation between the movement and the sleep efficiency, and based on the result, we propose a sleep efficiency measurement algorithm. In order to verify the performance of the proposed algorithm, we applied the algorithm to three polysomnography patients in hospitals and obtained the performance of an average absolute error within 3.9%.

본 논문에서는 원거리에서의 IR-UWB 레이더 센서기반 수면 효율 측정 알고리즘을 제안한다. IR-UWB 레이더로 수면 중 측정 가능한 호흡수, 심박수, 움직임 등의 생체 지표 중 움직임과 수면 효율과의 관련성을 분석하고, 움직임을 기반으로 한 수면 효율 측정 알고리즘을 제안한다. 이에 대한 타당성 및 성능검증을 위해 실제 병원에서의 수면다원검사 환자 3명에 대하여 본 알고리즘을 적용한 결과 평균 3.9% 이내의 절대오차를 갖는 검출성능을 얻었다.
