Definitions

  • the present invention addresses this, according to one aspect, by introducing electrodes with an inherent charge transfer mechanism which does not depend on the reaction potentials of the liquid to be transported, and for which the liquid is not taking part in electrochemical reactions.
  • the invention provides a textile comprising first and second conductive layers, at least one porous layer positioned between the first and second conductive layers, the first and second conductive layers being arranged to generate an electric field, and means for reversing the electric field.
  • the invention provides a textile pump with improved electrodes to avoid un-desired electrochemistry.
  • the electrode material is made from a hydrogen storing material such as palladium or nanochrystalline nickel.
  • a hydrogen storing material such as palladium or nanochrystalline nickel.
  • the oxidation and reduction of hydrogen occurs at only 0.3 V, hence an electric current causing electroosmotic liquid transport would happen at only 0.3 V, far below the reaction potential for water or sodium chloride solutions.
  • Such electrodes could thus safely transport even salt containing water.
  • the hydrogen is stored in the electrodes as neutral atoms or molecules, and moved through the porous liquid filled structure as ions.
  • An important aspect disclosed herein is the incorporation of a device which counts the number of ions (charge) passing from one electrode to the other. As these ions are the current carriers, this can be done by an automatic measuring of the current (i.e. the current is proportional to the number of hydrogen ions transported). After applying the current for a certain period in one direction, the cathode would become saturated with hydrogen and the process would stop.
  • an electronic control system connected to the charge counting system would reverse the voltage (regeneration step) from time to time in order to avoid the saturation of one electrode or the emptying of the other.
  • the forward pumping could be applied during hard activity with high perspiration rates, and the regeneration could be carried out under dryer conditions or when the jacket is not in use.
  • Electrodes In a new system electrodes (conductive layers) are partially pre-filled with hydrogen, to a known degree.
  • the system would automatically limit itself so as no electrode is saturated or totally emptied of hydrogen (in which case the hydrogen cycling would no longer work).
  • the maximum time of operating the system in one direction would depend on the current, which again depends on voltage and liquid conductivity. For a given cycle it would also depend on the degree of hydrogen saturation in the electrodes from previous cycles. 4. There could also be any number of periods with no voltage applied, during which the hydrogen contents of each electrode would remain constant.
  • ions different from hydrogen would be the charge carriers, e.g. silver-silver chloride electrodes.
  • the charge counting and controlling system would be the same, however.
  • 1 is a porous textile or membrane where the liquid transport is to be induced by an electric field and current
  • 2 is a conductive layer (first electrode)
  • 3 is a conductive layer (second electrode)
  • A is a point where current is measured
  • V is a voltage source.
  • 4 is an electronic control system connected to the current measurer A to reverse the voltage (regeneration step) from time to time in order to avoid the saturation of one electrode or the emptying of the other
  • Nanocrystalline nickel or other hydrogen storing metals could be used for the electrodes.
  • Thin porous metal foils could be prepared by laser cutting a non porous foil, or by electroplating.

Abstract

L'invention porte sur un textile, qui comprend des première (2) et seconde (3) couches conductrices, au moins une couche poreuse (1) positionnée entre les première et seconde couches conductrices, les première et seconde couches conductrices étant agencées de façon à générer un champ électrique, de sorte qu'un courant passe entre les couches conductrices de façon à induire un transport de liquide, et de façon à provoquer la réception d'ions au niveau de la seconde couche conductrice, des moyens de mesure (A) agencés de façon à mesurer la quantité de charge transférée entre les première et seconde couches conductrices durant une opération de transport de liquide, les moyens de mesure étant aptes à tenir compte de toute variation du courant ou de la tension durant l'opération de transport de liquide, et des moyens de commande (4) agencés de façon à commander une opération de régénération afin de régénérer la seconde électrode par transfert, par l'intermédiaire de celle-ci, d'une quantité de charge sensiblement égale à la quantité mesurée, de façon à provoquer l'éviction des ions de la seconde couche conductrice, et de façon à régénérer ainsi la couche conductrice.
