Abstract

In certain embodiments an electrode array for epidural stimulation of the spinal cord is provided where the array comprises a plurality of electrodes disposed on a flexible polymer substrate; said electrodes being electrically connected to one or more lead wires and/or connection points on an electrical connector; where the electrodes of said array are bonded to said polymer so that the electrodes can carry an electrical stimulation signal having a voltage, frequency, and current sufficient to provide epidural stimulation of a spinal cord and/or brain in vivo or in a physiological saline solution, without separation of all or a part of an electrode from the polymer substrate.
