Abstract: A textile includes first and second conductive layers and at least one porous layer positioned between the conductive layers. The first and second conductive layers are arranged to generate an electric field whereby a current passes between the conductive layers inducing liquid transport and causing ions to be received at the second conductive layer. A measurement device is arranged to measure the amount of charge transferred between the first and second conductive layers during a liquid transport operation, the device taking account of any variation in current or voltage during the liquid transport operation. A control device is arranged to control a regenerating operation to regenerate the second electrode by transferring via it an amount of charge substantially equal to the measured amount so as to cause ions to be removed from the second conductive layer and thereby regenerate the conductive layer.
