ABSTRACT:
A position touch sensor having a substrate and a resistive layer disposed on the substrate. At least one pair of electrodes is positioned on the resistive layer. A portion of one electrode is spaced from a portion of another electrode to produce an overlapped resistive region between the spaced portions of the electrodes. An insulating region extends into and terminates in the overlapped resistive region from a resistive region of the resistive layer outside the overlapped resistive region. A method for controlling the flow of current through a resistive layer for converting physical position information on the resistive layer into electrical signals. The method includes determining a dimension of a length of a generally continuous resistive section which is to be located in the resistive layer. The dimension of the length is determined through the use of electrical excitation in the resistive layer. A first insulating region is disposed in the resistive layer to form a first boundary of the generally continuous resistive section. Subsequently and at a distance from the first insulating region essentially equaling the dimension of the length, a second insulating region is disposed in the resistive layer to form a second boundary of the generally continuous resistive section such that current may be conducted through the generally continuous resistive section between the first and second insulating regions.
