When touched on the tongue, the experts claim that the so called "electronic lollipop" is able to trick taste receptors using an electronic signal.
The procedure for measuring the amount of tongue surface moisture was as follows: filter paper cut into 10 mm squares and a sealing bag were weighed in advance using an electronic scale.
As model problem we designed a procedure to predict levels of ferrocene, TCNQ and Ru bipy 32+ using a voltammetric electronic tongue employing a set of noble electrodes; i.e. Au, Pt, Ir and Rh.
Five cross selective electrodes comprising cyanide, thiocyanate, and iodide coated graphite electrodes CGEs were used as sensing parts of an electronic tongue for simultaneous determination of cyanide, thiocyanate, and iodide ions in the presence and the absence of chloride ion as a coexisting ion.
Changes in another electrochemical property, the surface potential can also be followed using classical potentiometry [57],[58] and using this technique makes the construction of an electronic tongue feasible [59].
In this work, two sets of voltammetric sensors -prepared using different strategies- have been combined in an electronic tongue to evaluate the complete antioxidant profile of red wines.
As far as the classification of water containments are concerned, Martínez-Máñez et al. (2005) developed an electronic tongue for the qualitative analysis of natural waters using Fuzzy ARTMAP neural network with success rate higher than 93%.
An experimental verification of new conception of an electronic tongue on the base of an array of low selective sensors that produce light-induced photovoltaic signals is presented.
A unique modification of simplex design was applied to an electronic tongue (E‐Tongue) analysis in bitterness masking formulation optimization.
