Abstract
Description
도 2: 종래 기술의 공지된 기기의 측정과 비교한, 본 발명에 따른 센서를 이용한 상이한 포름알데히드 농도의 측정에 대한 시간의 함수로서의 저항의 곡선을 나타낸다. 실선은 순수 In4Sn3O12 상을 가지는 본 발명에 따른 센서의 측정에 해당하고, 점선은 Appliedsensor MLC (2.3 V)에 해당하고 파선(dashed line)은 Figaro TGS 2620 (5.0 V) 센서에 해당한다. 로그적인 플롯 도시로 인해 본 발명에 따른 센서에 대한 센서 신호가 종래 기술의 공지된 센서의 신호에 비해 상당히 더 크다는 시각적인 비교를 즉시 확인할 수 있다. 개별적인 신호 단계와 관련되는 농도는 20, 40, 80, 100, 120, 160 및 180 ppb이고, 이후 순서가 반복된다.
도 3: 습한 공기 (50 % 상대 습도)에서 상이한 포름알데히드 농도에서 시간의 함수로서 센서 신호의 곡선을 나타낸다. 선행 기술에 공지된 Figaro (사각형) 및 Appliedsensor (삼각형)의 기준 센서로 측정한 센서 신호에 비하여, 향상된 In4Sn3O12 상 (원)의 센서신호가 매 농도 영역에서 분명하게 확인가능하다. 종래 기술에 널리-공지된 상기 두가지 기준 센서는 모두 본 발명에 따른 센서와 유사하게, 저항의 변화에 기초하여 작동하나, 이들의 감응성 층이 이산화 주석을 기초로 하고 있다.
도 4: 종래 기술에 공지된 두 가지 기준 센서에 비교한, 본 발명에 따른 센서의 민감도를 나타낸다. 사각형은 Figaro TGS 2620에 해당하고, 삼각형은 Appliedsensor MLC에 해당하고 점 또는 별은 서로 다른 일(day)에서의 본 발명에 따른 In4Sn3O12 센서의 민감도를 표시한다. 민감도의 정의에 따르면, 여기서 분석물 농도의 변화에 비교한 저항의 변화가 분석물 농도에 대해 도시된다. 본 발명에 따른 센서가 종래 기술의 공지의 기준 센서의 민감도보다 100배 더 높은 민감도를 가진다는 것이 분명히 확인가능하다.
