There is a necessity to include sensors (resistors) in the design of organic electronic devices in order to extend the range ofpossible applications, mentioned in the last iNEMI roadmap. It is essential to identify potential organic resistive materials, the processes and methods to structure them and to characterize their resistive properties on flexible substrates. A material widely used in organic electronics is the intrinsically conductive polymer (ICP) poly (3, 4-ethylendioxythiophene) doped with polystyrene sulfonate acid (PEDOT:PSS). In this paper wefocus on the pulsed stress behavior ofthis conductive polymer, normally used as a conductive layer and the resulting changes of the resistive properties.
