  • Patent number: 11249577
    Abstract: A touchpad and a sending unit for the same are provided. The sensing unit has two electrode layers and a separation assembly. The separation assembly has multiple deformation rooms and multiple gap assemblies. The deformation rooms communicate with the gap assemblies. The gap assemblies communicate with the exterior environment. When the upper electrode layer is pressed and deforms in the deformation rooms, the air in the deformation rooms is discharged through the gap assemblies so that the air does not accumulate in the remaining unstressed spaces to avoid resistance and to maintain the normal operation of the force sensing function.

  • Publication number: 20120013571
    Abstract: A three-dimensional touch sensor is constructed from a two-dimensional capacitive touch sensor in association with a conductive layer and an elastic insulator or with an insulation layer and an elastic conductor. When the three-dimensional touch sensor is touched, the two-dimensional capacitive touch sensor positions the touch point in a sensing plane, and the elastic insulator or the elastic conductor deforms responsive to the pressure and thus generates a capacitance variation, from which a sensing value in the perpendicular direction is derived related to the magnitude of the pressure.
