Effects of carbon nanotubes on electrical contact resistance of a conductive Velcro system under low frequency vibration

Experimental measurements of electrical contact resistance are presented for a conductive Velcro connector with spayed-on carbon nanotubes under low frequency vibration. Several factors affecting the electrical contact resistance of the Velcro connector, such as the type of carbon nanotube used, the density of the carbon nanotubes, the electrical load, the frequency, and the load amplitude of vibrating load, are analyzed. The role of carbon nanotubes in reducing electrical contact resistance is discussed from the view point of lubrication and damping.
