Structural Stability of the Serpentine-Patterned Micro Electrode Under the Influence of External Forces
The flexibility of a micro electrode is a crucial parameter that significantly affects its mechanical performance, and a serpentine-patterned structure is known to increase the flexibility of soft robots. In this study, the structural characteristics of a gold film with a serpentine structure were numerically investigated for the micro electrode to reach a higher degree of flexibility. To evaluate the structural stability of the electrode, torsional moment, compressive and tensile forces were applied in a complex manner to the electrode with various values of curvature for the serpentine shape. The numerical analysis of the von Mises stress of the film was carried out using COMSOL Multiphysics, ver. 5.2a. The results were graphically depicted, and the case of a micro electrode with the highest structural stability was derived.
