Claim:
1. A device comprising: an electric field applying assembly adapted to generate an electric field having a discrete electric field profile, wherein the electric field applying assembly comprises a plurality of electrodes in electrical contact with the electrical interface region; a conducting volume; and an electrical interface region, provided between the conducting volume and the electric field applying assembly, the electrical interface region arranged such that the discrete electric field is applied to the electrical interface region by the electric field applying assembly at a location spaced from the conducting volume; wherein the electrical interface region comprises at least an ionically conductive material arranged adjacent to and in contact with the conducting volume; such that the discrete electric field applied by the electric field applying assembly is smoothed by the electrical interface region so that the electric field profile established within the conducting volume is substantially continuous.
