Electrical properties of brush contacts made of bulk carbon nanotube forest are significantly better than the presently used commercial products due to the unique and intimate surface interaction of the former on the nanoscale. The image displays the nanotube block used, the measurement setup, and the resistance fluctuations for the carbon nanotube and the conventional brush setups.
