Nonlinear Modeling of Voltammetric Sensor Signals: Application to the E-Tongue Measurement
IEEE Sensors Journal, 2020The phenomena associated with electrochemical processes contribute to considerable nonlinearity on the response of the voltammetric sensor system. Motivated by the lack of nonlinear models of voltammetric systems, this paper reports an improved model that incorporates the system nonlinearity.

E-Nose and e-Tongue combination for improved recognition of fruit juice samples
Food Chemistry, 2014There are many important challenges related to food security analysis by application of chemical and electrochemical sensors. One critical parameter is the development of reliable tools, capable of performing an overall sensory analysis. In these systems, as much information as possible is required in relation to smell, taste and colour.

Voltammetric e-tongue for the quantification of total polyphenol content in olive oils
Food Research International, 2013Abstract This work presents the application of a voltammetric electronic tongue made from an array of polypyrrole modified screen printed electrodes in the qualitative and quantitative analysis of phenolic compounds found in virgin olive oils. Virgin olive oil samples in the form of emulsions were analyzed by sensors using cyclic voltammetry.

ARMAX Modeling and Impedance Analysis of Voltammetric E-Tongue for Evaluation of Infused Tea
IEEE Sensors Journal, 2019This paper presents a modeling technique to analyze the performance of the electrodes of a custom made voltammetric e-tongue. In this methodology, autoregressive moving average models are estimated for five working electrodes of the e-tongue made of different noble metals in classifying three different classes of infused tea.
