1. A method of manufacturing a textile-based hydrogel electrode, the method comprising the steps of:
coupling a conductive structure to a textile-based backing layer;
depositing a hydrogel material onto the conductive structure to form a hydrogel body that is in contact with a specified portion of the conductive structure; and
applying a stabilizing coating to at least a portion of the hydrogel body;
wherein the specified portion of the conductive structure comprises a first material that ionically interacts with the hydrogel material to form an ionic interface between the hydrogel body and the conductive structure, and wherein the ionic interface is configured to generate an electrical signal through the conductive structure corresponding to a biopotential change proximate to the ionic interface.
