文摘

We developed an actuator that uses an IrO2·2H2O/VGCF/IL gel electrode. The electrochemical and electromechanical properties of IrO2·2H2O/VGCF/IL actuators were examined. The electrode in this actuator system exhibited behavior similar to that of both an electrostatic double-layer capacitor and a faradaic capacitor. This actuator generated strain values that surpassed those of SWCNT-based actuators. The frequency dependence of the displacement response was successfully simulated using an electrochemical kinetic model similar to that used with SWCNT-based actuators.
