Abstract

Selon l'invention, on peut éliminer les effets de l'eau sur un capteur chimique à guide d'ondes optique par application d'un revêtement hydrophile qui créé une pseudo chemise d'eau. Le revêtement hydrophile absorbe l'eau de sorte que le guide d'ondes ait un indice de réfraction constant. Le revêtement hydrophile peut atteindre des conditions d'équilibre dans un environnement à humidité relative élevée, ou bien il peut être prétraité par exposition à l'eau dans un environnement à basse humidité relative. On peut, pour constituer ledit revêtement, utiliser toute une variété de polymères.
