ABSTRACT:
An electrical brush having at least one conductive element and at least one conditioning material coated on the at least one conductive element wherein the conditioning material has a composition and thickness on the conductive element such that, as deposited on a moving contact surface in the course of brush operation, the conditioning material can have an average film thickness S<˜1 μm so that current can be conducted by means of electron tunneling through a film thickness of the deposited conditioning material of Si≦12 nm thickness over a fractional area fC, greater than 0.01 of a foot print of the conductive element in a current conductive area.
