Abstract:
A device for detecting elements in a fluid environment includes at least one acoustic resonator having a surface designed for fixing of elements. The resonator is configured for generating and measuring Lamb waves fostering generation of symmetrical Lamb waves. The device analyzes the resonance frequency of the resonator to determine the variation of the resonance frequency of the symmetrical Lamb waves representative of the presence of the elements.
