Distributed Impedance Model of Ionic Polymer-Metal Composite Actuators
This paper discusses a distributed system modeling of the electrical impedance of ionic polymer-metal composites from the point of view of the electrode roughness. A diffusion-like equation is derived from the distributed circuit model which represents the fractal-like distribution of the polymer-electrode interface. The port-Hamiltonian representation of the system is also shown. In the experiment, the frequency response of the impedance is measured under various conditions.
