The element has a substrate (101) comprising movable ions. An electrode (102) is fixed to the substrate. An electrical conducting element (104) is electrically connected to the electrode, and is designed with a distal part (103). The distal part is integrated into the substrate. The electrical conducting element comprises a tip and/or a groove in the substrate, where the shape of the groove corresponds to that of the distal part so as to obtain a tip effect. The conducting element forms a blind hole. |
