ABSTRACT An electrographic touch sensor having Z-axis capability. In one embodiment, a uniform resistive coating (30) is applied to one surface of a substrate (12) and within this coating (30) orthogonal electrical fields are produced. Overlying the resistive coating is a flexible sheet (40) having a conductive layer, and interposed between the resistive coating and the conductive layer is an array of a material (32) having a substantially greater resistivity than that of the resistive coating (30). A Z-axis coordinate of a touched point on the sensor, related to the pressure force applied, can be obtained. This Z-axis coordinate is related to the change in the effective contact resistance between the resistive coating and the pick-off sheet caused by the pressure/force, and that change is "enhanced" by the high resistance array and thereby enables different values of pressure/force to be determined.
