Non-Uniformly Charged Ionic Polymer-Metal Composite (IPMC) Actuators: Electromechanical Modeling and Experimental Validation (Journal Impact Factor: 3.481)

Fevereiro 2012

An IPMC composite is an electroactive material that behaves in an electric field similarly to biological muscles. This intelligent material is leading to a new emerging technology called non-uniformly charged IPMC actuators. This paper introduces first an IPMC analytical modeling approach for its electromechanical characterization. The model considers, for the first time, the action of gravitation force in its electric and mechanic characteristics, which is important for large IPMC actuators. To demonstrate the efficacy of the model, two non-uniformly charged IPMC actuators were fabricated and tested. Experimental results are presented to validate the model and verify its effectiveness in the design of nonuniformly charged IPMC actuators.
