Abstract

La présente invention vise un capteur de pression capacitif (10) composé de deux disques (11, 12) d'alumine qui se joignent en périphérie dans une position prédéterminée, parallèles l'un à l'autre, définissant ainsi un logement (14). Au moins un des deux disques (11) joue, de par sa conception, le rôle d'une membrane élastique. Un enduit de nickel pur (16, 18) est appliqué à la surface de chaque disque par dépôt autocatalytique en solution aqueuse; à la surface de ces deux disques montés en vis-à-vis, des armatures (17, 20, 21) sont réalisées en donnant une texture précise à l'enduit de nickel. Les armatures de capacitance sont reliées à un circuit électronique à l'extérieur du logement (14) par le biais de couches additionnelles de nickel appliquées dans des trous métallisés (30, 31, 32) en même temps que l'enduit de nickel pur.
