1. An electrode array comprising:

  • (a) at least two hydrogel islands, wherein at least two of the hydrogel islands have a corresponding electrode contacting said hydrogel island;

    (b) a flexible insulating substrate comprising an electrode region, a torsion relief region, and a connector region; and

    (c) conductors located on said substrate electrically connecting the electrodes to the connector region,wherein;

    all the electrodes are located in the electrode region;

    the connector region and the electrode region are connected together through the torsion relief region;

    the torsion relief region is narrower than the connector region and is connected to a long side of the electrode region, the long side of the electrode region being defined as the long side of the smallest rectangle that encloses all the electrodes; and

    the connector region comprises a tip region and a stop region, the tip region arranged at an edge of the electrode array and the stop region arranged adjacent to the tip region, the stop region being wider than the tip region.
