• weighed sample of the substance mixture was taken and heated up to 60 °C for a few hours in order to evaporate the residual moisture. The remaining dry residue was weighed and proportioned, yielding the dry substance content of the mixture. See Supporting Information File 1 for details. Electronic tongue

Electronic tongue mechanism Figure 4a shows the behavior of a liquid as a function of the time as it gets in contact with the transducer. Initially, the composite is dry, at a constant temperature, and traversed by a constant current (red part
