The electro-mechanical model of ionic polymer-metal composite (IPMC) is presented in this paper. Applied electric field moves mobile ions inside the polymeric membrane. As a result, the electroosmotic flow inside the material appears and the subsequent motion of actuator occurs. These physical effects are modelled with the help of the finite element analysis software.
An ionic polymer-metal composites (IPMC) actuator is widely used for converting the external and stored induced energy in mechanical displacement. In general, the work of IPMC actuator described by a system of nonlinear equations: Nernst-Planck equation, Poisson equation and the equation of solid mechanics, which is possible to solved in a complex only by using specialized software. The method of...
The actual problem of microrobotic is creating of low cost energy-efficient actuator for mobile microsystems, which are able to simulate the movement of biological objects. In this article, designed and fabricated experimental samples of ionic polymer-metal composite (IPMC) actuators are presented. Highresolution SEM was used to control the electrode thickness and structure. Method of focused ion...
