Abstract

L'invention concerne des systèmes, des procédés et des dispositifs pour produire des gouttelettes sensiblement uniformes. Le système comprend un récipient de stockage de fluide délimitant un réservoir de fluide, une membrane de séparation sur une extrémité du réservoir de fluide, au moins un canal capillaire sur une extrémité opposée du réservoir de fluide, un distributeur de solution et un actionneur piézoélectrique en contact avec une membrane de séparation. La membrane de séparation présente une épaisseur supérieure à environ 0,2 mm, et le distributeur de solution maintient le réservoir de fluide rempli de fluide de sorte que le fluide entre simultanément en contact avec la membrane de séparation et le canal capillaire. Le distributeur de solution maintient le réservoir de fluide sous pression pour créer un flux de fluide sortant du capillaire. L'actionneur piézoélectrique est en contact avec la membrane de séparation sur un côté opposé qui est en contact avec le fluide, et l'actionneur piézoélectrique transfère une onde de pression à travers le fluide dans le réservoir de fluide pour rompre le flux de fluide en gouttelettes uniformes.
