Riassunto analitico
The growing interest into multi-sensor systems able to determine general attributes of a process under monitoring, has recently involved the qualitative analysis of liquids; various methodologies to develop taste sensors, often referred to as “e-tongues” have been presented in the literature. The common concept in the different approaches, lies in the combination of signals originated by poorly specific sensors for the characterization of liquids.<br>The fundamental idea of this PhD work is to investigate how an adequate signal processing approach, applied to a mature and affordable sensor technique (voltammetry), can address the issue of extracting an aggregate chemical information, useful to characterize the liquid under measurement. <br>In this Thesis, a general description of electronic taste sensor systems is given, followed by a description of the working principles of e-tongues based on voltammetry. Then, the methodology that represents the core of this PhD Thesis work is introduced: the sensor device, the control software and the data processing approach are described in this sequence. Finally, a few case studies are shown, selected according to their relevancy with respect to the peculiarities of the approach described in this Thesis.<br>
