NOVELTY – Producing polyurethane-acrylate membrane coated with a nickel (Ni) magnetic film involves producing a diaphragm and producing a microcoil, where diaphragm is produced by preparing polyurethane acrylate membrane (PA), performing acid pretreatment, nucleating, performing contact deposition and magnetic deposition. USE – Method for producing polyurethane-acrylate membrane coated with a nickel magnetic film used in micro pumps, sensors and / or microvalves (all claimed). DETAILED DESCRIPTION – An INDEPENDENT CLAIM is included for a method for producing electromagnetic actuated diaphragm micro pump, which involves activating with stannous chloride and palladium (II) chloride and depositing inner layer or contact layer.
