  • Biomedical electrode comprising discontinuous primer layer
    Patent number: 10695553
    Abstract: Articles and methods of making articles are described. In one embodiment, an electrode is described, comprising an ionically-conductive hydrogel layer comprising a first major surface and opposing major surface. The electrode further comprises a discontinuous primer layer disposed on the first major surface ionically-conducting hydrogel layer and an electrically conductive member or a connector component thereof, in contact with the first major surface of the ionically-conducting hydrogel layer. In another embodiment, an article is described comprising a hydrogel layer comprising a first major surface and opposing major surface; a discontinuous hydrophobic primer layer disposed on the first hydrogel layer; and a hydrophobic adhesive or hydrophobic backing bonded to the primer and discontinuous hydrophobic primer layer of the hydrogel.
