Abstract
(DE)
Die Erfindung betrifft eine Gassensorvorrichtung. Diese weist eine Multi-Transducer-Matrix (10a) mit Transducerpixein (20) auf, welche Rezeptorpartikel (30) von unterschiedlichen Rezeptorsorten (1 - 5) aufweist, wobei erste Transducerpixel (20) jeweils einen oder mehrere Rezeptorpartikel (30) aufweisen und zweite Transducerpixel (20) jeweils keine Rezeptorpartikel (30) aufweisen. Die Multi-Transducer-Matrix (10a) weist mehrere Rezeptorpartikel (30) von jeder Rezeptorsorte auf. Ein Verfahren zum Herstellen der Gassensorvorrichtung umfasst ein Bereitstellen einer Multi-Transducer-Matrix (10a) mit Transducerpixein (20) und ein Aufbringen eines Gemisches auf die Multi-Transducer-Matrix (10a) welches Rezeptorpartikel (30) von unterschiedlichen Rezeptorsorten (1 - 5) und/oder deren Prekursoren enthält. Ein Verfahren zum Betreiben der Gassensorvorrichtung umfasst einen Kalibrierschritt in dem die Gassensorvorrichtung einer Referenzatmosphäre ausgesetzt wird und darauf geschlossen wird, dass Transducerpixel (20), die sich gleich verhalten mit Rezeptorpartikeln (30) der gleichen Rezeptorsorte (1 - 5) belegt sind.
(EN)
The invention relates to a gas sensor device. The device has a multi-transducer matrix (10a) comprising transducer pixels (20), which has receptor particles (30) of different receptor types (1-5), wherein first transducer pixels (20) each have one or more receptor particles (30) and second transducer pixels (20) do not have any receptor particles (30). The multi-transducer matrix (10a) has multiple receptor particles (30) of each receptor type. A method for producing the gas sensor device comprises providing a multi-transducer matrix (10a) with transducer pixels (20) and applying a mixture to the multi-transducer matrix (10a), which mixture contains receptor particles (30) of different receptor types (1-5) and/or their precursors. A method for operating the gas sensor device comprises a calibration step in which the gas sensor device is exposed to a reference atmosphere, and conclusions are drawn that transducer pixels (20) which behave the same are coated with receptor particles (30) of the same receptor type (1-5).

L'invention concerne un dispositif de détection de gaz. Celui-ci comporte une matrice à multiples transducteurs (10a) comprenant des pixels transducteurs (20), lesquels comportent des particules (30) de récepteur de différents types de récepteurs (1 - 5). Des premiers pixels transducteurs (20) comportent respectivement une ou plusieurs particules (30) de récepteur et des deuxièmes pixels transducteurs (20) ne comportent respectivement aucune particule (30) de récepteur. La matrice à multiples transducteurs (10a) comporte plusieurs particules (30) de récepteur de chaque type de récepteur. L'invention concerne également un procédé de fabrication du dispositif de détection de gaz, qui comprend les étapes consistant à fournir une matrice (10a) à multiples transducteurs comprenant des pixels transducteurs (20) et à appliquer un mélange sur la matrice (10a) à multiples transducteurs, lequel contient des particules (30) de récepteur de différents types de récepteurs (1 - 5) et/ou leurs précurseurs. L'invention concerne un procédé servant à faire fonctionner le dispositif de détection de gaz, qui comprend une étape d'étalonnage, dans laquelle le dispositif de détection de gaz est exposé à une atmosphère de référence et il est conclu que des pixels transducteurs (20) présentant un comportement identique sont dotés de particules (30) de récepteur des types de récepteurs (1 - 5) identiques.
