We report a study about the electrical response from a sliding contact made of a silver-
graphite brush and a brass ring. This study focuses specifically on the voltage variations due …

We present in this work the experimental results of shear stress applied to a rough metallic
interface. This interface was test using a weak DC current, measures of the voltage evolution …

When two surfaces are brought into contact and slide against each other, junctions are
formed at the interface. The dynamics of formation, rupture, and evolution of these junctions …

Lorsque deux surfaces sont mises en contact et glissent l'une contre l'autre, des jonctions
sont formées à l'interface. Les dynamiques de formation, de rupture et d'évolution de ces …

Signal transfer systems are used in some industrial or transport applications. These systems
have to transmit, through a sliding (pantograph/catenary) or a rolling (wheel/rail) multi …
