a Adhesive bandages and double-side tapes made of Electro-Ox hydrogels. b Images of the Non-Ox, Chem-Ox, and Electro-Ox hydrogel tapes on white patches. Scale bar = 10 mm. c Images of the Electro-Ox hydrogel tape stretched to more than seven times the original length. Scale bar = 10 mm. d Typical tensile stress–strain curves of the Non-Ox, Electro-Ox and Chem-Ox hydrogel tapes at an alginate-dopa concentration of 10 w/v%. e Typical stretch–relaxation curves of Non-Ox, Chem-Ox, and Electro-Ox hydrogel tapes. f Typical tensile stress–strain curves of Electro-Ox hydrogel tapes at various mass concentrations of electro-oxidized alginate-dopa (5.0, 7.5, 10.0, and 12.5 w/v%).
