Zusammenfassung:The device for detecting elements in a fluidic medium comprises at least one acoustic resonator having a surface intended for fixing the elements. The resonator includes means for generating and measuring Lamb waves, favouring the generation of symmetrical Lamb waves. The device analyses the resonant frequency of the resonator in order to determine the variation in the resonant frequency of the symmetrical Lamb waves representative of the presence of the elements.
