Claim 7:
8. A wearable biopotential measuring device comprising:
a support scaffold configured for wearing by a subject; and
a plurality of electrodes coupled to the scaffold so that when the support scaffold is worn by the subject, each of the plurality of electrodes are positioned proximate to a corresponding specified bodily structure of the subject, wherein each of the plurality of electrodes is configured to generate an electrical signal corresponding to a biopotential change of the corresponding specified bodily structure,
wherein at least one of the electrodes comprises 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 that is configured to generate the electrical signal corresponding to the biopotential change of the corresponding bodily structure.
