Abstract

L'invention concerne un dispositif de détection d'un gaz à analyser. Ce dispositif peut inclure un amplificateur de signal avec par exemple un transistor à film mince, film éventuellement semi-conducteur pouvant inclure un oxyde de métal qui peut interagir chimiquement avec le gaz à analyser, tel du monoxyde de carbone. Pour la détection du gaz à analyser, on fait varier la tension de grille du transistor dans le dispositif.
