In the last several years we have developed a novel class of micro electrodes for neuronal recording and stimulation. The electrodes are fabricated by synthesizing high density carbon nanotube islands on lithographically defined, passivated titanium nitride conductors on a silicon dioxide substrate.
Recently, we have also developed a flexible version of these electrodes. The enhanced electrochemical properties of the electrodes, their flexible and simple micro-fabrication preparation procedure as well as their bio-compatibility and durability suggest that carbon nanotube electrodes are a promising platform for high resolution neuronal coupling. These electrodes are currently explored primarily for surface EMG and EEG applications.
