Abstract

La présente invention concerne un dispositif permettant de déterminer la quantité de liquide, notamment d'eau ou de transpiration, échangée entre un système, notamment un organisme vivant, et son environnement. De manière caractéristique, ledit dispositif comporte un élément plat constitué d'un matériau apte à absorber ledit liquide, ledit élément plat comportant : - des moyens de fixation étanche audit système ; - une zone d'absorption apte à venir en contact avec ledit liquide ; et - une zone réactive qui comprend des microcapsules/microsphères, ladite zone réactive étant apte à absorber ledit liquide provenant de ladite zone d'absorption, lesdites microcapsules/microsphères comportent une coque soluble ou dispersible dans ledit liquide, ladite coque et ledit colorant présentent des couleurs différentes, ladite coque étant creuse et entoure un colorant soluble ou dispersible dans ledit liquide et éventuellement apte à changer de couleur au contact dudit liquide et/ou ladite coque est pleine ou éventuellement creuse et contient un colorant soluble ou dispersible dans ledit liquide et apte à changer de couleur au contact dudit liquide et ladite zone réactive est recouverte d'un film protecteur étanche audit liquide et transparent à la lumière.The present invention relates to a device making it possible to determine the quantity of liquid, in particular water or perspiration, exchanged between a system, in particular a living organism, and its environment. Characteristically, said device comprises a flat element made of a material capable of absorbing said liquid, said flat element comprising: - means for tight fixing to said system; - an absorption zone capable of coming into contact with said liquid; and - a reactive zone which comprises microcapsules / microspheres, said reactive zone being capable of absorbing said liquid coming from said absorption zone, said microcapsules / microspheres comprise a shell which is soluble or dispersible in said liquid, said shell and said dye have different colors, said shell being hollow and surrounds a dye soluble or dispersible in said liquid and possibly capable of changing color on contact with said liquid and / or said shell is solid or optionally hollow and contains a dye soluble or dispersible in said liquid and suitable in changing color on contact with said liquid and said reactive zone is covered with a protective film impervious to said liquid and transparent to light.
