Abstract

La présente invention concerne un inhalateur (1) pour l'inhalation d'un aérosol, comprenant un évaporateur (2) pour l'évaporation d'un liquide. L'évaporateur (4) comporte une céramique électriquement conductrice (6) pour recevoir et évaporer la substance à évaporer, et un dispositif de commande (10) de l'inhalateur (1) alimente la céramique (6) en énergie en fonction de la température de la céramique (6) mesurée au moyen d'une unité de mesure de température (9), permettant ainsi une commande améliorée de l'aérosol produit.
