1. A device arranged for carrying-out a bioelectrical interaction with an individual through electrodes and detecting undesired contact of an electrode with the individual, said device comprising:

  • a plurality of electrodes arranged to receive a physiological electrical signal when brought into contact with an individual'"'"'s skin;

    testing means arranged to deliver a second electrical signal to an input of the electrodes, said electrodes being further arranged to generate a response signal upon receipt of the second electrical signal;

    control unit arranged to analyze the first electrical signal and to actuate the testing means upon an occurrence of a predetermined event in the first electrical signal; and

    lead-off detection means arranged to verify an integrity of the contact of said electrodes by analyzing the response signal and detecting a parameter related to said integrity.
