A non-enzymatic sensor element with selectivity is used to sense a concentration of a target analyte and includes a substrate and an electrode assembly. The electrode assembly is connected to the substrate and includes a working electrode, a reference electrode and an auxiliary electrode. The working electrode includes a conductive layer, a catalyst layer and a selective layer. The conductive layer is connected to the substrate. The catalyst layer is connected to the conductive layer and includes a catalyst for oxidizing the target analyte. The selective layer is connected to the catalyst layer and includes an ionic liquid having a high affinity with the target analyte. The target analyte passes through the selective layer and contacts with the catalyst layer, and the target analyte is oxidized by the catalyst.

Non-enzymatic sensor element with selectivity and non-enzymatic sensor

A fabricating method of a non-enzyme sensor element includes a printing step, a coating step and an electroplating step. In the printing step, a conductive material is printed on a surface of a substrate to form a working electrode, a reference electrode and an auxiliary electrode, and a porous carbon material is printed on the working electrode to form a porous carbon layer. In the coating step, a graphene film material is coated on the porous carbon layer of the working electrode to form a graphene layer. In the electroplating step, a metal is electroplated on the graphene layer by a pulse constant current to form a catalyst layer including a metal oxide.
