抄録(英) Multi-Walled CNT (MWCNT) are synthesized on a silicon wafer and sputter coated with a gold film. The planar surfaces are mounted on the tip of a piezo-electric actuator and mated with a gold coated hemispherical surface to form an electrical contact. These switching contacts are tested under conditions typical of MEMS relay applications; 4V, with a static contact force of 1mN, at a low current between 20-50mA. The evolution of contact resistance is considered in a newly developed test procedure. The contact resistance performance is then linked to a study of the contact changes in the surface. The contact surfaces have been shown to exhibit a transfer process over a large number of switching cycles. The continuous monitoring of contact resistance can be used for the identification of surface failure. The results show that for the surfaces presented the contact resistance remains stable for between 80 and 120 million switching cycles. Interestingly the number of bounces is related to the fine transfer failure mechanism.
