1. A nerve interface device comprising:
at least one cuff portion having an assembled position in which the at least one cuff portion forms at least part of a passageway for receiving a nerve along a longitudinal axis passing through the passageway; and
a first ring of electrodes and a second ring of electrodes mounted on the at least one cuff portion, each of the first ring of electrodes and the second ring of electrodes comprising a plurality of electrodes, and wherein each electrode in the first ring of electrodes has a corresponding longitudinally-aligned electrode in the second ring of electrodes so as to form a plurality of pairs of electrodes spaced apart from each other along the longitudinal axis;
and wherein the at least one cuff portion comprises a spatially asymmetric configuration about a central axis perpendicular to the longitudinal axis to provide a passive imbalance and impedance mismatch along the longitudinal axis of the nerve interface device.
