1. A multibend sensor, comprising:
a reference strip having a first plurality of electrodes, wherein each of the first plurality of electrodes is adapted to receive a signal;
a sliding strip having a second plurality of electrodes, wherein each of the second plurality of electrodes is adapted to transmit at least one signal, wherein the sliding strip moves with respect to the reference strip, wherein an end portion of the reference strip and an end portion of the sliding strip are secured together by a common end portion, wherein the common end portion effects the movement of the sliding strip with respect to the reference strip; and
measurement circuitry adapted to process signals received by the first plurality of electrodes, wherein the processed signals provide information regarding the relative position of the sliding strip to the reference strip.
