Abstract

L'invention concerne une technologie qui concerne un inhalateur qui permet à un utilisateur de déterminer si un état de stress a été réduit en raison de l'inhalation. L'inhalateur comprend : un boîtier; une unité d'embout qui est disposée sur le boîtier et comporte un embout; une électrode de mesure de taux de transpiration qui est disposée sur le boîtier de façon à être exposée de l'extérieur et sert à mesurer un taux de transpiration émotionnelle d'un utilisateur; et une unité de commande qui analyse un degré de stress de l'utilisateur sur la base du taux de transpiration émotionnelle mesuré à l'aide de l'électrode de mesure de taux de transpiration et notifie à l'utilisateur le résultat d'analyse.
