Title

(FR) SYSTÈMES DE MICROFLUIDIQUE UTILISANT L'ÉNERGIE ACOUSTIQUE SUPERFICIELLE ET LEUR PROCÉDÉ D'UTILISATION
Abstract
(EN)
A microfluidic system including a piezoelectric substrate (1), a wave generation means (5) for generating a wave in the piezoelectric substrate, and a rigid secondary substrate (11) coupled to said piezoelectric substrate (1) and providing a working surface (12) for the system, the secondary substrate (11) being formed of a relatively chemically inert material, and the coupling of the piezoelectric substrate (1) with the secondary substrate (12) being provided by a fluid coupling layer (13) located between the piezoelectric substrate (1) and the secondary substrate (12) overlaying the piezoelectric substrate (1). In one application, the system may be used to synthesize zeolite nanocrystals via atomization of a liquid droplet (15).
(FR)
L'invention porte sur un système de microfluidique comprenant: Un substrat piézoélectrique (1), un générateur d'ondes (5) produisant des ondes à l'intérieur du substrat piézoélectrique, un substrat rigide (11) relié au substrat piézoélectrique (1) et servant de surface de travail (12) au système. Le substrat rigide (11) peut être fait d'un matériau relativement inerte chimiquement. Le couplage du substrat piézoélectrique (1) et du substrat rigide (11) étant assuré par une couche fluide située entre eux et recouvrant le substrat piézoélectrique (1). Dans une application, le système peut servir à synthétiser des nanocristaux de zéolite par atomisation de gouttelettes liquides (15).
