Paper Abstract

We study ionomeric polymer-metal composite (IPMC) actuators in situations where the strip of actuator acts either on maximum mechanical power or maximum amplitude of actuation. We apply a modified equivalent circuit of IPMC muscle which takes into account the surface resistance change while material bends. In case of series of bending acts, the first actuation of IPMC actuator is performed by a relaxed actuator, it bends over it's full length. During the next movements the most of the energy is caught by fore-part of actuator. The explanation of that effect is given.
