수면 무호흡증 관리를 위한 섬유센서 기반의 슬립 모니터링 스마트 웨어 개발 = A Study on the Development of Sleep Monitoring Smart Wear based on Fiber Sensor for the Management of Sleep Apnea

다국어 초록 (Multilingual Abstract)

In this study, we will propose its usefulness by developing an unconstrained wearable monitoring system using stretch fiber sensors and attaching clothing-integrated designs that allow patients to undergo examinations in an environment familiar to overcome the limitations of existing tests and minimize the occurrence of skin allergies, such as discomfort in adhesive tools. sleep apnea causes a variety of complications, and standard sleep polysomnography is expensive and measurement discomfort is considered. Long-sleeved T-shirts for adult men were developed to develop wearable sleep apnea monitoring smart clothes, and real-time measurements of breathing rate which are measured based on fibrous sensors, oxygen saturation, and airflow in sleep apnea diagnosis indicators. According to the results of measuring the gauge factor, the gauge factor 20.3 was verified in the sample No. 4. The breathing rate was measured at three large breaths, with a maximum breathing rate of 2048 ml. After measuring oxygen saturation, it measured the change in oxygen saturation while holding its breath and oxygen saturation was 69.45 percent, showing a minimum measurable oxygen saturation of 70 percent. The results of washing are generally equivalent to gauge factor 18 level, and durability of washing has been demonstrated. Through this study, we developed wearable sleep apnea monitoring smart clothes that are readily available in the home and confirmed that three indicators of respiration rate, breathing flow and oxygen saturation are measurable.

본 연구에서는 수면무호흡증이 다양한 합병증을 유발하는 질병으로서, 이를 위한 표준화된 수면다원검사가 고가이며 측정이 불편함을 고려하여, 환자가 익숙한 환경에서 검사를 받을 수 있도록 스트레치 섬유센서를 이용한 무구속 상태의 웨어러블 모니터링 시스템을 개발하고자 한다. 또한, 의복과 일체화된 디자인으로 제품화하여 그 유용성을 제안하고자 한다. 성인 남성용 롱 슬리브 티셔츠 형태로 착용형 수면무호흡 모니터링 스마트 의류를 개발하여, 수면무호흡 진단 지표 중 섬유형 센서를 기반으로 측정하는 호흡수(breathing rate)측정용 섬유센서, 산소포화도(oxygen saturation), 호흡기류(airflow)를 실시간 측정하였다. 최적의 조합비 샘플 4가지를 통한 gauge factor를 측정한 결과, gauge factor 20.3을 확인하였고, 3회 숨을 크게 내쉴 때 호흡유량이 최대 2048ml 였다. 산소포화도 69.45%로 최소 측정 가능 산소포화도 70% 정도의 결과를 나타내었다. 세탁 후 인장에 따른 센서 성능 평가 결과는 전체적으로 gauge factor 18 수준의 값으로, 세탁에 대한 내구성이 입증되었다. 본 연구를 통하여 수면무호흡증 환자의 수면효율이 떨어지고 여러 합병증을 동반하는 문제에 대해, 가정에서 쉽게 사용할 수 있는 착용형 수면무호흡 모니터링 스마트 의류를 개발하여 호흡수, 호흡유량, 산소포화도의 3가지 지표를 측정 가능함을 확인하였다.
