Abstract

In this paper, we carried out the impedance measurements of the bucky-gel actuators and analyzed the results by means of the porous electrode model. We also measured the displacement of the same actuators by applying sinusoidal voltages of various frequencies. The frequency dependence of the displacement responses is discussed in relation with the impedance properties of the bucky-gel electrodes. The electrochemical equivalent circuit of the bucky-gel actuator is discussed on the basis of the impedance analysis. Accordingly, we are able to develop an electrochemical model allowing to analyze the behavior of these actuators.
