Abstract
A top layer comprises a flexible support and a plurality of hard elements anchored in a binder over the flexible support, and a method of forming the same is provided. In one embodiment, certain ones of the hard elements have a contact surface adapted to contact the conductive surface, with the binder being disposed below the contact surface of each of the certain ones of the hard elements. In another embodiment, the top layer comprises a flexible support, a plurality of hard elements are anchored in a binder over the flexible support such that certain ones of the hard elements have a top surface and the binder is disposed below the top surface of each of the certain ones of the hard elements, and a hard material coating is disposed over the plurality of hard elements and the binder, thereby creating a contact surface of the hard material coating at locations corresponding to the top surface of the certain ones of the hard elements.
