Abstract

A conductive mesh (2) is a mesh comprising first members (21) and second members (22), spaced so as to form a grid. The conductive mesh (2) is provided as a single conductive layer, having the requisite strength to support itself without need of a plastic support or a non-conductive layer. The conductive mesh (2) may comprise polyethylene, though it will be understood that other plastics may be employed. The conductive mesh (2) also comprises carbon in order to provide conductive properties.
