E.  aUso de polímeros condutores em língua eletrônica para a análise de vinhos e cafés.  c2003  aAn electronic tongue comprising a polyaniline derivative (POEA) and sulphonated lignin in different supra-molecular architectures was used in the evaluation of coffee and wine samples. Three sensing units were dipped into the liquids, furnishing remarkable results that are in good agreement with the opinion of specialists. The sensor could detect subtle differences in wines from the same grape and vintage, but from distinct wine makers, due to a standard process adopted by one of them. In addition, the device can group coffee samples in distinct clusters, regarding to their quality, as much as in the same way they were previously classified by professionals.  aFilmes ultrafinos  aPolímeros condutores  aSensor  aUnidades sensoriais1 aFIRMINO, A.1 aALMEIDA, T.
