A device having a polymeric support with a surface for contact with skin, an array of solid polymeric microneedles integral with the support and projecting outward from the surface of the support provided for contact with the skin, and an electrode. The microneedles and the surface of contact of the support with the skin are formed of a crosslinked hydrogel, non-electron-conductive in the dry state and electrolyte-conductive upon contact with an aqueous fluid. The electrode is arranged in contact with the hydrogel provided to swell upon contact with an aqueous fluid and is free of direct contact with the skin. A method for preparing the device and uses thereof are also described.
