전도성 및/또는 반전도성인 높은 종횡비의 분자 구조의 네트워크를 포함하는 필름(103)을 포함하는 기구가 제공된다. 기구는 또한, 필름(103)의 독립형 영역(101)이 적어도 2개의 지지 위치 사이에 연장되도록 적어도 2개의 지지 위치에서 필름(103)을 지지하도록 배열된 프레임(102)을 포함한다. 필름(103)에 전기적으로 커플링된 2개 이상의 전기 접촉 영역, 및 이들 전기 접촉 영역은 0.01 암페어 내지 10 암페어의 전류로 필름(103)의 독립형 영역(101)을 가로질러 전기 전하를 통과시키도록 배열된다.

Apparatuses comprising films with free-standing region

An apparatus, comprising a film (103) comprising a network of conductive and/or semi-conductive high aspect ratio molecular structures is presented. The apparatus also comprises a frame (102) arranged to support the film (103) at least at least two support positions so that a free-standing region (101) of the film (103) extends between the at least two support positions. The two or more electrical contact areas electrically coupled to the film (103), and these electrical contact areas are arranged to pass electric charge across the free- standing region (101) of the film (103) at a current between 0.01 and 10 amperes.
