Carbon nanotube (CNT) agglomerates can be aligned along the field lines between adjacent electrodes to form conductive bridges. The present invention is directed to a stepwise process of dielectrophoretic deposition of CNTs to form conducting bridges between adjacent electrodes spanning lengths over 50 microns. The CNT bridges are permanently secured using electrodeposition of the conducting polymer polypyrrole. Morphologies of the CNT bridges formed within a frequency range of 1 kHz and 10 MHz are employed and explained as a consequence of interplay between dielectrophoretic and electroosmotic forces. Postdeposition heat treatment increases conductivity of CNT bridges likely due to solvent evaporation and resulting surface tension inducing better contact between CNTs.
