Title
(EN) PIEZOELECTRIC FLUID DISPENSER
(FR) DISTRIBUTEUR DE FLUIDE PIÉZOÉLECTRIQUE
Abstract
(EN)
Fluid delivery devices and methods are described, where the device may comprise a piezoelectric actuator operatively coupled to an ampoule with fluid, under a preloading force. The ampoule may comprise a thin-walled thermoplastic package which includes one or more apertures positioned on the wall of the ampoule. The piezoelectric actuator may be configured to clamp at least partially around the circumference of the ampoule and apply oscillations to its wall. The oscillations, typically in ultrasonic frequency, produce cycles of acoustic pressure in the fluid, leading to ejection of the fluid droplets or streams from the apertures.
(FR)
L'invention concerne des dispositifs et des procédés de distribution de fluide, le dispositif pouvant comprendre un actionneur piézoélectrique couplé de manière fonctionnelle à une ampoule contenant un fluide, sous une force de préchargement. L'ampoule peut comprendre un emballage thermoplastique à paroi mince qui comprend une ou plusieurs ouvertures positionnées sur la paroi de l'ampoule. L'actionneur piézoélectrique peut être conçu pour serrer au moins partiellement la circonférence de l'ampoule et appliquer des oscillations au niveau de sa paroi. Les oscillations, en règle générale dans la fréquence ultrasonore, produisent des cycles de pression acoustique dans le fluide, conduisant à l'éjection des gouttelettes ou des flux de fluide à partir des ouvertures.
