Abstract
IPMC (Ionic Polymer Metal Composite) actuators have numerous promising applications in designing electroactive soft motion structures. It was reported that the bending behavior of Selemion CMV-based IPMC in response to the electrical stimulation was quite susceptible to the environmental absolute humidity, and the environmental absolute humidity increase appeared to cause the unstable bending of Selemion CMV-based IPMC. Previously a circuit model for the analysis of Selemion CMV-based IPMC bending behavior was proposed and it actually resulted in quite successful prediction of bending behavior. However, it does not provide us with any information of bending stability. In this study, using Simulink - Matlab, an open loop model was built, based on the circuit model, the stability analysis of Selemion CMV-based IPMC bending was carried out.
