Nonuniformly Charged Ionic Polymer-Metal Composite Actuators: Electromechanical Modeling and Experimental Validation
— 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 gravit...
متن کاملNonlinear Parametric Identification of an IPMC Actuator Model
Ionic polymer metal composite is a class of electro-active polymers which are very attractive smart actuators due to its large bending deflection, high mechanical flexibility, low excitation voltage, low density, and ease of fabrication. These properties make IPMC a proper candidate for many applications in various fields such as robotics, aerospace, biomedicine, etc. Although the actuation beh...
متن کاملChallenges to the application of IPMC as actuators of planetary mechanisms
Ion-exchange polymer membrane metallic composites (IPMC) are one of the electroactive polymers (EAP) that were shown to have potential application as actuators. The recent introduction of perfluorocarboxylategold composite with tetra-n-butylammonium and lithium cations instead of sodium made the most significant improvement of the material's electroactivity. Under less than 3 volts, such IPMC m...
متن کاملModeling and open-loop control of IPMC actuators under changing ambient temperature
Because of the cost and complexity associated with sensory feedback, open-loop control of ionic polymer–metal composite (IPMC) actuators is of interest in many biomedical and robotic applications. However, the performance of an open-loop controller is sensitive to the change in IPMC dynamics, which is influenced heavily by ambient environmental conditions including the temperature. In this pape...
متن کاملAnion Effects on the Ion Exchange Process and the Deformation Property of Ionic Polymer Metal Composite Actuators
An ionic polymer-metal composite (IPMC) actuator composed of a thin perfluorinated ionomer membrane with electrodes plated on both surfaces undergoes a large bending motion when a low electric field is applied across its thickness. Such actuators are soft, lightweight, and able to operate in solutions and thus show promise with regard to a wide range of applications, including MEMS sensors, art...
