Abstract： PEN films were prepared by vacuum deposition. Their electrical bistable properties were studied under conditions of various circuit parameters.A decrease of time needed for impedance transition with increasing circuit current was observed. The film impedance showed a nonlinear characteristics and then data fitting was done for the nonlinearity. Furthermore, an energy effect was found during the transition, i.e. when the applied voltage exceeds a threshold, the energy consumption keeps invariable.
