Deflection Analysis of Ionic Polymer Metal Composites (IPMC) Actuators for Bionic Joints

Abstract:

Ionic Polymer Composite Material (IPMC) is a flexible material and has concealed many benefits to inspire the scientists and researchers to explore its physiognomies for real-world applications in various fields. Currently, the research area of IPMC can be alienated into two branches. One deals with the upgrading of the material properties to make it further advantageous and dependable while the other encompasses the consideration of new application capacities. In this paper, a new application of IPMC is recommended to stimulate a rigid link that can imitate a bionic knee joint for a grass hopper. Secondly, force-deflection mathematical model has been developed for the proposed design to investigate the amount of deflection that can be achieved by a certain force provided by the IPMC material strips. In this paper, the model is derived for the upward movement of the link; however the same model can be applied to the reverse direction because of the unanimity of the material properties and specifications.
