Gold coated carbon-nanotube surfaces as low force electrical contacts for MEMS devices: Part II, fine transfer mechanisms
Gold coated carbon-nanotube surfaces as low force electrical contacts for MEMS devices: Part II, fine transfer mechanisms
Material transfer in switching contacts is considered at very low currents, (below 20mA). The transfer process is critical to a wide range of electronic switching technologies and is a limiting factor for MEMs relays. A test system is described and characterized for bench-marking surfaces. This is followed by a study of Multi-walled CNT’s (MWCNT’s), synthesized on a silicon planar and sputter coated with a gold film. The planar surfaces are mounted on the tip of a piezo-electric actuator and mated with a Au coated hemispherical surface. The switching contacts are tested under conditions typical of MEMS relay applications; 4V, 1mA; with a static contact force of 1mN, results are presented on the bounce process and on the opening characteristic with respect to the melting and boiling voltages for the materials tested.

Abstract
Material transfer in switching contacts is considered at very low currents, (below 20mA). The transfer process is critical to a wide range of electronic switching technologies and is a limiting factor for MEMs relays. A test system is described and characterized for bench-marking surfaces. This is followed by a study of Multi-walled CNT’s (MWCNT’s), synthesized on a silicon planar and sputter coated with a gold film. The planar surfaces are mounted on the tip of a piezo-electric actuator and mated with a Au coated hemispherical surface. The switching contacts are tested under conditions typical of MEMS relay applications; 4V, 1mA; with a static contact force of 1mN, results are presented on the bounce process and on the opening characteristic with respect to the melting and boiling voltages for the materials tested.
