Abstract
A device includes a substrate, a top touch panel, and an electrode supported by the substrate including a conductive compressible material extending from the substrate to the top touch panel. Another electrode is supported by the substrate and arranged to form an electric field coupling with the electrode including the compressible material. A touch sensitive region is transferred from the substrate to the top touch panel by the compressible material.
