Modeling of actuation and ion migration behavior in electro-active paper actuator

Actuation mechanism of chitosan-blended cellulose (CBC) electro-active paper (EAPap) bending actuator was studied using a theoretical model and experimental data. The model of bending displacement of EAPap is combined ion traveling model with multi-layer cantilever beam model. Also, the result of the model is compared with experimental data. From this model, we can predict actuation behavior as well as redistribution of ions inside of CBC EAPap under different humidity levels and electric fields. Therefore, the actuation model of EAPap can be applied to investigate the electro-mechanical actuation behavior of EAPap devices such like artificial muscles, micro robots and other various actuators.
