Abstract:
1. A device comprising: a substrate; a top touch panel; a first conductive compressible electrode supported by the substrate and extending from the substrate to the top touch panel; a second conductive compressible electrode supported by the substrate and extending from the substrate to the top touch panel; a third electrode connected to the first and second conductive compressible electrodes; a fourth electrode supported by the substrate and arranged to form an electric field coupling with the first conductive compressible electrode, wherein the first conductive compressible electrode and the fourth electrode are physically separated from each other such that an object touching the top touch panel proximate to the first conductive compressible electrode causes a change in capacitance between the first conductive compressible electrode and the fourth electrode; and a fifth electrode supported by the substrate and arranged to form an electric field coupling with the second conductive compressible electrode, wherein the second conductive compressible electrode and the fifth electrode are physically separated from each other such that an object touching the top touch panel proximate to the second conductive compressible electrode causes a change in capacitance between the second conductive compressible electrode and the fifth electrode.
