Abstract

EL ELECTRODO (19) DE LA INVENCION ACTUAL TIENE UNA SUPERFICIE METALICA COMPRENDIDA DENTRO DE UNA ABERTURA PRODUCIDA POR UN LASER (18) DONDE LA SUPERFICIE METALICA SE EXTIENDE DENTRO DE UNA TRAYECTORIA METALICA DE CONDUCCION ELECTRONICA (12B) Y ESTA CUBIERTO DE UNA CAPA DE ENCAPSULACION (16) PARA AISLARLO ELECTRICAMENTE. LA CAPA DE ENCAPSULACION ALREDEDOR DE LA SUPERFICIE METALICA, TIENE UNA ABERTURA QUE PERMITE LA EXPOSICION DE DICHA SUPERFICIE METALICA DESDE LA CAPA DE ENCAPSULACION. LA TRAYECTORIA METALICA Y LA CAPA DE ENCAPSULACION RESIDEN EN UN SUSTRATO (10), Y SE PRODUCEN DESDE LOS CIRCUITOS DE CAPAS. LA CELULA ELECTROQUIMICA TIENE EL ELECTRODO ANTES MENCIONADO YUXTAPUESTO SOBRE OTRO ELECTRODO (14). ESTE ELECTRODO ES PARTE DE LA CAPA METALICA DE MODELO QUE SE PRODUCE POR MEDIO DE CIRCUITOS DE CAPAS. EL ELECTRODO SE EXTIENDE HACIA DENTRO DE UNA TRAYECTORIA METALICA CONDUCTORA ELECTRICA (12A) ESPACIADA Y AISLADA ELECTRONICAMENTE DE LA OTRA TRAYECTORIA. EL AISLAMIENTO PODRA SUMINISTRARSEMEDIANTE EL RECUBRIMIENTO DE UN MATERIAL DE ENCAPSULACION QUE CUBRE LA TRAYECTORIA CON EXCEPCION DEL SEGUNDO ELECTRODO. EL MATERIAL DE ENCAPSULACION NO CUBRE EL SEGUNDO ELECTRODO DEBIDO A SU RETIRADA POR LASER Y/O ENMASCARAMIENTO DURANTE LA PRODUCCION DE LOS CIRCUITOS DE CAPAS. AMBOS ELECTRODOS ESTAN CUBIERTOS CON UN ELECTROLITO LIQUIDO PERMEABLE AL OXIGENO (32) QUE PROPORCIONA CONTACTO IONICO ENTRE LOS DOS ELECTRODOS. LOS ELECTRODOS Y EL ELECTROLITO ESTAN CUBIERTOS CON UNA O MAS MEMBRANAS PERMEABLES AL OXIGENO (30, 34), Y ESTAS, JUNTO CON LAS TRAYECTORIAS METALICAS CONDUCTORAS RESIDEN EN UN SUSTRATO. LA CELULA SE UTILIZA PARA DETECTAR OXIGENO EN LOS LIQUIDOS CUANDO SE APLICA UNA POTENCIA NEGATIVA AL ELECTROLITO PRODUCIDO POR LASER RELACIONADO CON EL OTRO ELECTRODO A TRAVES DE LAS TRAYECTORIAS QUE ESTAN EN CONTACTO CON LOS CONDUCTORES (24, 26) PARA CONTACTO ELECTRICO EXTERNO DESDE EL SUSTRATO
