Abstract

L'invention concerne un système destiné à améliorer les propriétés de cavitation de couches de liquide proches de la surface, ainsi qu'un applicateur d'ultrasons flexible, adaptable et déformable utilisé à des fins de traitement. Les phénomènes de cavitation dans la zone proche de la surface lors du traitement de systèmes biologiques sont difficiles à contrôler et à maintenir constants. Selon l'invention, l'effet d'une cavitation dans des couches de liquide proches de la surface peut être amélioré au moyen d'un agent de cavitation (6) enrichi en gaz et au moyen d'un applicateur d'ultrasons, de préférence un applicateur d'ultrasons à structure en feuilles (10), pour des ultrasons situés dans une plage de fréquence comprise entre 20 et 100 kHz, cet applicateur d'ultrasons pouvant s'adapter de façon particulièrement satisfaisante à des surfaces (11) et étant formé de feuilles PVDF assemblées. Le dispositif et l'applicateur d'ultrasons selon l'invention sont destinés en particulier au traitement de systèmes biologiques dans le domaine des sciences de la vie.
