1. A method of making a microchannel neural interface device comprising:
placing a plurality of metal wires in a curable composition, wherein the curable composition comprises a polymerizable compound and wherein the metal wires have a diameter approximately equal to the diameter of a nerve axon;
curing the curable composition to form a polymeric object having a plurality of metal wires embedded in the polymeric object;
removing the metal wires from the polymeric object to form a plurality of microchannels within the polymeric object; and
placing one or more hollow cylindrical electrodes into one or more of the microchannels, wherein each of the one or more hollow cylindrical electrodes is an elongated electrode with a hollow part of the electrode oriented coaxially with the longitudinal axis of the microchannels.
