1. A textile-based hydrogel electrode comprising:
a textile-based backing layer;
a conductive structure coupled to the textile-based backing layer;
a hydrogel body comprising a hydrogel material in contact with at least a first portion of the conductive structure; and
a stabilizing coating covering the hydrogel material of at least a portion of the hydrogel body,
wherein the first portion of the conductive structure and the hydrogel material form an ionic interface configured to generate an electrical signal through the conductive structure corresponding to a biopotential change proximate to the textile-based hydrogel electrode.
