Abstract

A device for transferring electrical charge between a first element and a second element is provided. The elements have relative rotational motion therebetween. The device has a body including a multiplicity of electrically conductive fibers. A substantial portion of the fibers extend in a substantially parallel direction, parallel to a first axis. The body includes a first contact area. The body defines an aperture therein. The body further includes a second contact area on the periphery of the aperture spaced from the first contact area. The first contact area is for contact with the first element and the second contact area is for contact with the second element.
