Research on Ag-IPMC force electric model and force output characteristics

In order to investigate the mechanical properties of Ag-IPMC artificial muscles, establishing the mathematical model of Ag-IPMC under non-electrically actuated conditions by superelastic large deformation equation. The mechanical simulation and experimental comparison of Ag-IPMC with different moisture contents were carried out. The piezoelectric coefficient from the bimorph piezoelectric model was equivalently analogized to the calculating of the Ag-IPMC model so that the model was more suitable for the characteristics of nonlinear large deformation of Ag-IPMC. According to the data from the analysis, a conclusion can be drawn: when the moisture content of Ag-IPMC was within a certain range, with the decrease of moisture content of Ag-IPMC, the strain was small under low voltage or low moisture content conditions. Meanwhile, the smaller the strain, the smaller the extrusion of the root where the place was clamped causing by the Ag-IPMC deformation. The mechanical properties of Ag-IPMC were the coupling result of comprehensive factors. Simply improving the performance of any single item would affect the overall mechanical properties.
