Abstract
Sheet type position sensors might trigger a wealth of applications in flexible electron-ics. Progress in the field is rapidly embracing the demonstration of simple, transparent and flexible large area sensor concepts reacting sensitively to temperature changes caused by incident light. A promising concept for an efficient yet simple and thus low cost, flexible and transparent light spot position sensor is based on ferroelectric and conduc-tive polymers. In this contribution we present a concept for a one dimensional light point localization model system using the position dependent signals generated by pyroelectric films when excited by a laser diode. The sensor consists of a PVDF stripe with PEDOT:PSS (DMSO) electrodes on both sides. For the theoretical description the detector can be treated mathematically analogous to a transmission line. The solutions of the equations and the experi-mental results are in agreement.
