Title
(EN) MICROFLUIDIC APPARATUS FOR THE ATOMISATION OF A LIQUID
(FR) APPAREIL MICROFLUIDIQUE POUR L'ATOMISATION D'UN LIQUIDE
Abstract
(EN)
An apparatus (1 ) for the atomisation of a liquid including: a piezoelectric substrate (5) having at least one working surface (7), at least one electrode (9) supported on the piezoelectric substrate (5), a signal generating means (21 ) for applying an ultrasonic signal to said electrode (9) for generating a surface acoustic wave (SAW) in the working surface (7) of the piezoelectric substrate (5); a liquid delivery arrangement (11) including a wick (17) in contact with the working surface (7) for delivering liquid thereof, wherein liquid delivered to the working surface (7) is atomised by SAW irradiation.
(FR)
La présente invention se rapporte à un appareil (1) destiné à l'atomisation d'un liquide et comprenant : un substrat piézoélectrique (5) comportant au moins une surface de travail (7), au moins une électrode (9) soutenue sur le substrat piézoélectrique (5), un moyen de génération de signal (21) destiné à appliquer un signal ultrasonore à ladite électrode (9) pour produire une onde acoustique de surface (SAW) dans la surface de travail (7) du substrat piézoélectrique (5) ; un aménagement de distribution de liquide (11) comprenant une mèche (17) en contact avec la surface de travail (7) pour la distribution de liquide, le liquide distribué sur la surface de travail (7) étant atomisé par exposition à la SAW.
