The present invention relates to a sensor for an electronic tongue or nose for analysing a sample or detecting a target. The sensor comprises a support, on one surface of which a plurality of sensitive areas are located, each sensitive area comprising at least one receptor and being capable of transmitting a measurable signal generated by the interaction of at least one constituent of the sample or one target with at least one receptor. The sensor is characterised in that it comprises at least three sensitive areas that differ from one another in terms of their respective receptor compositions, at least one of the sensitive areas comprising a mixture of at least two different receptors, while the two other sensitive areas each comprise at least one of the two receptors.
