	The frequency dependence of the generated strain shown in this figure is attributed to the electrochemical kinetics (a double-layer charging kinetic model). At low frequencies of the applied rectangle voltage, the carbon nanotube dispersed in the electrode layer is fully charged and actuator exhits maximal strain. On the contrary, at higher frequencies, there is not enough time for the dispersed SWNTto be fully charged and strain generated by the actuator is reduced remarkably. Hence, the amplitude of the accumulated charge decreases with the increase in the frequency and its phase is delayed to the applied voltage.
