Abstract

SE TRATA DE UN INVENTO PARA LA FABRICACION DE UN SENSOR DE DISTINTAS FUERZAS DE PRESION POR MEDIO DE LAS CUALES EL SENSOR SE PONE EN FUNCIONAMIENTO. EN ESTE PROCESO LAS RESISTENCIAS DE CAPA DENSA SE APLICAN A UN SUBSTRATO METALICO A TRAVES DE VIAS DE CONDUCCION O, SI SE PREFIERE, A UN A CAPA DE AISLAMIENTO. FINALMENTE LA SUPERFICIE DEL SENSOR ES TRATADA DE TAL MANERA QUE ES SITUADO EN PARALELO CON RESPECTO A LA SUPERFICIE INFERIOR DEL SUBSTRATO
