This paper describes a novel configuration of electrodes used to actuate ionic polymer-metal composites (IPMCs). IPMCs are smart materials usually actuated by a pair of electrodes fixed against them. In this study, the anode is fixed to the actuator while the cathode only touches it. It was verified that the IPMC can bend enough to lose connection. This configuration obtains oscillation from a DC input, characterized by quick separations and slow returns. Actuation based on transient contact between IPMCs and electrodes has the potential of simplifying current mechanisms.
