Abstract

Organic thin-film sensors based on the thermal evaporation and dip-coating of polyaniline, and on the Langmuir-Blodgett deposition of a vanadium porphyrin, have been fabricated. The d.c. electrical resistances of the individual elements are found to exhibit different changes on exposure to simple vapours (water, propanol, ethyl acetate and acetone). These data have been used successfully to train an artificial neural network, based on a back-propagation technique, to recognize two of the vapours.
