摘要： Dry electrodes are electrodes for attachment to human skin without skin preparation or the use of electrolyte gels. The electrode includes a substrate, electrically conductive particles with at least one point, in contact with the substrate, a supporting layer that envelopes the electrically conductive particles with points that protrude from the supporting layer, and an electrical connector. Some electrodes have an electrically conductive substrate, other electrodes have an electrically conductive supporting layer.

摘要： The disclosed thermally bondable adhesive tape backing has a pressure-sensitive adhesive at a surface and a thermoplastic polyurethane adhesive at an opposite surface for thermal bonding to a device. The thermoplastic polyurethane adhesive softens and melts at a relatively low temperature. Therefore, melting of thermoplastic polyurethane adhesive is achieved while the pressure-sensitive adhesive remains in place and is not pressed away at the region of the thermal bonding.

摘要： Crosslinked (meth)acrylate-based pressure sensitive adhesives are capable of attachment to mammalian skin for at least 10 days. The crosslinked adhesive composition includes a crosslinked (meth)acrylate-based copolymer free from polar groups, and a hydrogenated hydrocarbon tackifier resin. The crosslinked adhesive composition is prepared by photocrosslinking a hot melt processable blend of a (meth)acrylate copolymer and a hydrogenated hydrocarbon tackifier resin. The (meth)acrylate copolymer is the reaction product of an alkyl (meth)acrylate monomer with alkyl groups of 4-22 carbon atoms and are free of polar groups, and a co-polymerizable photocrosslinker.

摘要： Transfer tape articles are suitable for preparing dry electrodes. The transfer tape articles include a release liner and a conductive transfer tape layer adjacent to the release liner. The conductive transfer tape layer includes a layer of adhesive and a discontinuous layer of electrically conductive shaped particles, where the shaped particles have at least one point. The adhesive envelopes the conductive particles, and at least one point of the electrically conductive particles protrudes from the conductive transfer tape layer. The conductive transfer tape layer can be a single layer of adhesive or a multi-layer construction including a first adhesive layer, a support layer, and a second adhesive layer.
