Abstract

Die Erfindung bezieht sich auf eine Sensoranordnung zum Messen einer Gaskonzentration, insbesondere von CO, H2, NOx und/oder Kohlenwasserstoffen. Um mit relativ geringem Aufwand, insbesondere geringem Kostenaufwand, eine genaue Messung zu ermöglichen, ist die Sensoranordnung versehen mit einem auf einem Substrat (2) aufgebrachten, eine oder mehrere Isolationsschichten (4, 6, 8, 10) aufweisenden Isolationsmaterial, mindestens einer in oder auf dem Isolationsmaterial vorgesehenen ersten Elektrodenstruktur (12, 13), mindestens einer in oder auf dem Isolationsmaterial vorgesehenen, von der ersten Elektrodenstruktur in vertikaler Richtung beabstandeten zweiten Elektrodenstruktur (14, 15), einer gassensitiven Schicht (16), die an die erste Elektrodenstruktur (12, 13) und die zweite Elektrodenstruktur (14, 15) angrenzt, und einer in dem Isolationsmaterial (4, 6, 8, 10) vorgesehenen Heizleiterstruktur (7).
