Abstract: The device includes an electrolysis cell (C) comprising: a closed variable volume first chamber (2) containing an electrolyte that gives off gas under the effect of an electrolysis voltage applied to electrodes (3, 4) in contact with the electrolyte, the gas given off causing the first chamber to expand; and a variable volume second chamber (7) containing the active principle, said second chamber opening out to the outside via an orifice (11) enabling the active principle to be delivered; the total volume of the two chambers (2, 7) being constant, such that expansion of the first chamber causes the volume of the second chamber to be reduced and gives rise to a corresponding controlled expulsion of the active principle contained therein. According to the invention, the two chambers (2, 7) are separated from each other by a flexible wall (6) uniformly subjected to the pressure resulting from gas being given off in such a manner as to reduce the volume of the second chamber (7) and expel the active principle; and the first chamber (2) contains a liquid electrolyte in which the electrodes (3, 4) that extend over the major portion of the length of said first chamber are immersed so that the electrodes are always at least in part in contact with the electrolyte regardless of the position of the device.
