1. A cuff-electrode which is placed around a biological tissue as an extraneural, sleeve-shaped electrode, comprising:

  • layers of non-conductive material having provided thereon raised electrodes, individual ones of said raised electrodes being contacted via strip conductors disposed between the layers of non-conductive material;

    wherein at least one of the layers of non-conductive material is ensured a cuff-shaped form via one of mechanical pretensioning and use of a shaped memory material; and

    wherein said layers of non-conductive material having said raised electrodes thereon are designed in a finger-shape such that fingers thereof lie snugly next to one another in a nerve embracing state of the cuff electrode, said raised electrodes being rod-shaped electrodes provided in an arrayed arrangement on said fingers such that a load pressure on the biological tissue is minimal.
