Device and method for studying a study area by means of an acoustic wave

摘要

A device includes a substrate 5, an emission source 1 emitting an acoustic beam from the first surface 7 of the substrate 5 towards the second surface 6 of the substrate 5, first reflection element 11 arranged so that, after reflection, the beam has a propagation direction substantially parallel to the second surface 6 and through a study area 3, and second reflection element 12 for reflecting the beam after crossing the study area 3 in the direction of the first surface, towards a receiver 10. The device is useful in the field of bioMEMS and labs-on-a-chip, and in particular makes it possible to leave one of the surfaces of the substrate free, for example for observation of the study area in parallel by element of an optical microscope. Moreover, the device facilitates the production of elements for the focussing or divergence (lenses) or reflection (mirror) of the acoustic beam.
