Abstract[EN] Method for manufacturing at least one flexible, biocompatible and implantable neuronal microprobe, which comprises the steps of: providing a rigid substrate layer (100); providing a soluble polymer layer (110) on said rigid substrate layer; providing a first polymer layer (130); etching at least one opening (151; 152) in said first polymer layer; providing a two-dimensional conductive layer (160) on said first polymer layer; etching at least one microelectrode having at least one contact area in said two-dimensional conductive layer; providing a finishing assembly (195) on the microelectrode; and dissolving said soluble polymer in a solution (120). The resulting microelectrode (160) is sandwiched between two polymer layers (190, 195), one of which comprises an opening (151; 152) for accessing said contact area.
[ES] Procedimiento de fabricación de al menos una micro-sonda neuronal flexible, biocompatible e implantable, que comprender las etapas de: proporcionar una capa de un sustrato rígido (100); proporcionar una capa de un polímero soluble (110) sobre dicha capa de sustrato rígido; proporcionar una capa de un primer polímero (130); grabar en dicha capa de primer polímero al menos una abertura (151; 152); proporcionar una capa de un material conductor bidimensional (160) sobre dicha capa de primer polímero; grabar en dicha capa de material conductor bidimensional al menos un microelectrodo provisto de al menos un área de contacto; proporcionar un ensamblaje de acabado (195) sobre microelectrodo; y disolver dicho polímero soluble en una solución (120). El microelectrodo resultante (160) queda intercalado entre dos capas de material polimérico (190, 195), una de las cuales comprende una abertura (151; 152) para acceder a dicha área de contacto.
