A micro-electrode array (A) is described comprising an insulating substrate (SUB) and a plurality of conductive paths (E, T, P) defined therein, each of which includes an electrode area (E) with microscopic dimensions, a connection area (P) with macroscopic dimensions, and a buried interconnection region (T), wherein the insulating substrate (SUB) is made of a first polymeric material, such as PDMS, and the conductive paths (E, T, P) are made of a second polymeric material, such as PEDOT. Furthermore, a method of manufacturing such micro-electrode array is described, based on the configuration of an insulating substrate (SUB) volume by replica molding on the first polymeric material through a prearranged master mould (M), bearing a configuration of microstructures (S) adapted to define a plurality of cavities (C); successively filling the cavities (C) with a second conductive polymeric material so as to constitute the electrode areas (E), the connection areas (P), and the interconnection regions (T); and arranging an insulating material sealing layer (B) for the filled cavities (C). |
