1. A system comprising:
at least one contact electrode;
at least one collector electrode;
at least one voltage source for applying a voltage between the at least one contact electrode and the at least one collector electrode; and
means for moving the system in a direction of movement;
wherein the at least one contact electrode is fitted in a suspended fashion, wherein the at least one contact electrode has a length L, and wherein the at least one contact electrode is wound on a coil and the length L of the at least one contact electrode can be increased by unwinding from the coil and decreased by winding onto the coil; and
wherein a bending stiffness of the at least one contact electrode with respect to an external force that acts on the at least one contact electrode counter to the direction of movement is lower than a bending stiffness of the at least one contact electrode with respect to an external force that acts on the at least one contact electrode transversely relative to the direction of movement.
