The two main goals of this Thesis are: (1) developing lightweight, flexible, and all- organic sensing materials that use electrical detection principles and (2) engineering simple prototypes that may use such sensing materials for pressure, temperature and relative humidity monitoring. When this Thesis was started, the preparation and properties of highly piezoresistive BL films composed of a polycarbonate (PC) matrix "self-metallized" with a polycrystalline layer of the organic molecular metal β-(BEDT-TTF)2I3 (were BEDT- TTF = bis(ethylenedithio)tetrathiafulvalene) had been re ported (Figure 1-3). 38 This BL film shows ability to sense tiny uniaxial deformations down to a minimum relative strain value of 10-4 %. This value was well below those of many conventional metal foil strain gauges. 39 In this context, covering polymeric films with organic molecular conductors different from β-(BEDT-TTF)2I3 was used as one of the key approach to achieve the first goal of this research project: the development of lightweight, flexible, and all- organic sensing materials with an electrical detection principle. The development of various sensor architectures allowing the use of different operated principles as a holistic approach to achieve the second main objective of the Thesis: the engineering of simple prototypes using the BL films for sensing pressure, temperature and relative humidity. |
