  • Device and method for detecting elements in a fluid environment
    Patent number: 8667845
    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.

  • Method for obtaining a layer of AlN having substantially vertical sides
    Patent number: 8460987
    Abstract: A method for producing a layer of AlN having substantially vertical sides relative to the surface of a substrate, including: the formation of an AlN growth layer on a substrate, the deposition of the AlN layer, on at least said growth layer, the formation of a mask layer over the AlN layer, at least one edge of which is aligned with at least one edge or side of the growth layer, in a plane which is substantially perpendicular to a surface of the substrate or a surface of the growth layer, and the etching of the AlN layer.

  • DEVICE AND METHOD FOR DETECTING ELEMENTS IN A FLUID ENVIRONMENT
    Publication number: 20110072901
    Abstract: 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.
