摘要: In this work, we explore a promising electroactive polymer (EAP), called ionic polymer-metal composite (IPMC) as material to use multi degree of freedom actuator. Configuration our interest is cylindrical IPMC with 2-DOF electromechanical actuation capability. The desired functionality was achieved by fabricating unique inter-digitated electrodes. First, 3D finite element (FE) model introduced design tool validate if the concept actuators would work. FE based upon physical transport processes-field induced migration and diffusion ions. Second, modeling fabricated prototype exhibiting output. has diameter 1 mm 20 length. We have successfully demonstrated that bending IPMCs feasible. Furthermore, experimental results given new insight into physics behind phenomenon IPMC.
