| چکیده | ||
| This paper aims to discuss the electromechanical behavior of an ionic polymer metal composite (IPMC) with electrodes made of platinum and polymeric membrane made of Nafion-117 in the structure of a gripper. Two methods are used in this research; the experimental method and the finite element method. After producing an IPMC with the mentioned properties and setting the gripper structure, the generated blocking force was measured and its ability to lift and move two external specimens made of aluminum and fish egg with a radius of "8.23"×"1" "0" ^(-4) m m was evaluated. The Same analysis was done by the finite element method. The magnitude of the distributed load is approximately equal to 590 N/m^2 . The surface area of the sample is equal to 115 〖mm〗^2. After conducting the statistical calculations, the concentrated force on the tip of the beam is 52.95×〖10〗^(-3) N and the results of the two methods are consistent with each other with an error of "0.092 % " . When a concentrated force is applied to the spherical sample, both pure aluminum and fish egg materials experience an identical maximum stress of 9.97 MPa. The maximum displacement for the aluminum sample is 0.613 µm, and for the fish egg sample, it is 2.62 µm. It has been concluded that this gripper is able to lift and move the mentioned samples and IPMC is a biocompatible material since it is compatible with the bio-sample (fish egg) considered in this research. | ||
