We present a study on an organic resistive switching device based on the heterojunction of a thin conducting polyaniline (PANI) layer and a ions containing gel (or solution). We have studied the device, characterized by a non-linear and rectifying response to the applied voltage, as a function of some chemical and geometrical parameters such as solution pH, ions concentration and junction contact area, finding out their influence on the device electrical parameters such as the saturation current, the activation voltage, and the response time. The study leads us to develop a physical model of the device and control its response through the fabrication process predicting also interesting properties obtainable with a device miniaturization.
