The present invention relates to a wettability switch that comprises an electrochemically active element having a wetting surface with switchable wetting properties. The electrochemically active element comprises an electrochemically active polymer, and surface active molecules each having a lyophobic portion and a lyophilic portion. In the wettability switch, each of said surface active molecules exposes one of said lyophobic portion and said lyophilic portion towards said wetting surface, and the identity of said portion depends on an electrochemical state of said polymer.

A device is disclosed for electrically controlled transport of ions between a source and a target electrolyte, including a source electrode and a target electrode. The electrodes are each capable of conducting ions, and the source electrode is arranged to receive ions from the source electrolyte and the target electrode is arranged to release ions to the target electrolyte. The device further includes an ion-conductive channel, arranged to receive ions from the source electrode and to release ions to the target electrode. Moreover, the ion-conductive channel is arranged to provide an ionic connection between the source and the target electrodes. The electrodes and the ion-conductive channel are formed of solid or semi-solid materials which are directly or indirectly attached to a support. In at least one embodiment, the device also includes a device for limiting an electronic current between the source and the target electrodes, such that at least after a voltage is applied across the channel a potential difference between the source and target electrodes is maintained, which potential difference effects ion transport from said source to the target electrode. An apparatus for transporting ions to or from a cell, use of the device for transporting ions to or from a cell, and methods of operating the device are also disclosed.
