Abstract
Description
도 2a는 본 개시의 예에 따른 MRF의 평면도를 도시한다.
도 2b는 본 개시의 예에 따른, MRF 및 별도의 보정(calibration) 스트립의 평면도를 도시한다.
도 2c는 본 개시의 예에 따른 MRF의 평면도를 도시한다.
도 3a는 전형적인 비-다한증 땀 수준의 손바닥 피부와 20 초간 접촉 후의 본 발명의 예에 따른 MRF를 도시하며, 이는 일부 모공에서의 활동적 땀 생성에 상응하는 반점형의 진한 스팟을 보여준다.
도 3b는 더 활동적인 땀 생성을 갖는 손바닥 피부와 20 초간 접촉한 후의 본 개시의 예에 따른 MRF 장치를 도시하며, 이는 약한 다한증을 나타내는 것일 수 있다.
도 3c는 정량적 측정을 위한 활성 분비샘의 임계값 검출의 예를 도시한다.
도 3d는 도 3a 비-다한증 (오른쪽) 및 도 3b 잠재적 다한증 (왼쪽)(이들은 도 3d의 부분의 확대도임)에서 샘플링된 손을 기록하기 위해 사용된 본 발명의 예에 따른 MRF 장치, 및 도 3c (왼쪽 위 영역)를 생성하는데 사용된 다양한 수분 수준의 1 μL 보정 용량의 세트를 도시한다.
도 4a는 단일 조작으로 넓은 영역 (예를 들어, 전체 발바닥)에 걸친 땀 생성을 기록하는 이 접근법의 능력을 나타내는 발자국을 도시한다. 중첩된 사각형은 도 4b를 위해 확대된 영역을 ¾”의 스케일 바(scale bar)와 함께 도시한다.
도 4b는 필름에 기록된 상세 부분 확대도를 나타내며, 개별 모공은 발바닥 표면의 피부 융기부 내에서 쉽게 식별 가능하다. 이 건강한 자원자에서 모든 모공이 활동적인 것은 아니며, 밝은 부분은 PVA 필름과 건조한 땀 분비관 개구부의 접촉 부족에 해당한다. 융기부는 수분 함량으로 인해 가시적이지만, 모공의 더 진한 착색과 비교할 때 쉽게 식별된다. 스케일 바 = 500μm.
도 5는 수분 노출 전에 부착된 하부 접착성 필름 스트립과 함께 결합된 2 개의 스타치-함유 필름을 도시한다. 접착성 필름 위에 놓인 필름 영역은, 피부 표면과의 접촉에 의해 침착된 수분 함량을 검출함에 있어서 증가된 감도를 나타낸다.
