1. A skin electrode for stimulation comprising; a superporous hydrophilic material having a first state and a second expanded state, in the second state the superporous hydrophilic material is breakable to at least partly enclose at least one hair, andan electrode surface for electrically stimulating the skin by driving current from the electrode surface through the hydrophilic material to the skin comprising the at least one hair,
wherein the superporous hydrophilic material comprises:
45.1% polymerized acrylamide,1.5% polymerized acrylic acid,32.6% polymerized sulfopropylacrylate potassium salt,0.8% polymerized methylene bisacrylamide, and20.0% inter-penetrating network former crosscarmelose sodium salt; or the superporous hydrophilic material comprises:50.1% polymerized acrylamide,1.7% polymerized acrylic acid,36.2% polymerized sulfopropylacrylate potassium salt,0.9% polymerized methylene bisacrylamide, and11.1% inter-penetrating network former crosscarmelose sodium salt; or the superporous hydrophilic material comprises:53.1% polymerized acrylamide,1.8% polymerized acrylic acid,38.3% polymerized sulfopropylacrylate potassium salt,0.9% polymerized methylene bisacrylamide, and5.9% inter-penetrating network former crosscarmelose sodium salt. |
