CPCs have been widely used for different sensors, due to its light weight, portability, flexibility, and low cost [90, 119]. The sensing mechanism of CPC sensors is based on the resistance variation of CPCs when experiencing external stimulus like mechanical deformation [120, 121], temperature variation [122, 123], and adsorption of vapors or organic solvent [124, 125]. The resistance of CPCs is affected by the evolution of conductive network under external stimulus [5]. These transient resistance change can be detected as a signal for sensing purpose.
