Abstract: A sensorized device for detecting analytes within a fluid comprising a piezoelectric substrate having an outer surface, at least one R-SAW emitting interdigital transducer arranged on the outer surface and arranged to emit a surface acoustic wave of the Rayleigh type, also-called R-SAW, in response to an electrical input signal, said R-SAW being emitted along a first emission direction x, and at least one SH-SAW emitting interdigital transducer arranged on the outer surface and arranged to emit a surface acoustic wave of the shear-horizontal type, also-called SH-SAW, in response to an electrical input signal, said SH-SAW being emitted along a second emission direction y.

Abstract: A method for the detection of analytes within a fluid, said method comprising the steps of prearranging a sensorized device (100) comprising at least one SAW sensor (110), said or each SAW sensor (110) comprising a substrate (115) having an outer surface (IIS?) comprising at least one piezoelectric portion, at least one emitting interdigital transducer (111) arranged on said piezoelectric portion of said outer surface (115?), said emitting interdigital transducer (111) arranged to emit a surface acoustic wave in response to an input electric signal, at least one reflector electrode (112) arranged on said outer surface (115?), said reflector electrode (112) arranged to reflect said acoustic wave towards said emitting interdigital transducer (111).
