Electroresponsive Hydrogel-Based Switching Components for Soft, Bioelectrical, and Fluidic Circuits

The development of various soft components for fluid circuits is conducive to the further development of soft robots. The electroresponsive hydrogel is applied to build a functional oscillator in the study conducted. Based on the multiphasic mixture model, the deformation of the hydrogel under external electric fields is analyzed through COMSOL Multiphysics simulator. Owing to the characteristics of the hydrogel that it will deform in response to electric field, the hydrogel is employed to control fluidic circuits, resulting in a novel controllable functional soft oscillator.
