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.
