Abstract (en)

[origin: WO2012172253A1] The present invention relates to a piezoelectric sensor for the detection and characterization of at least one biochemical element in a fluid, consisting of a piezoelectric substrate (1) exhibiting at each of its opposite faces at least one conducting surface forming electrodes (2, 3), said electrodes (2, 3) being linked to an electrical generator, one at least of said surfaces being wrapped in a functionalized film (4), characterized in that said electrodes (2, 3) form transmission lines exhibiting a zone constituting an induction loop for the excitation of said piezoelectric substrate (1), the link between said electrodes (2, 3) and said generator being ensured by inductive coupling. It also relates to a system implementing such a sensor, as well as to applications of such a sensor.
