CONTACT RESISTANCE TYPE SENSOR FOR MEASURING INTENSITY OF FORCE, CONTACT RESISTANCE TYPE SENSOR FOR MEASURING INTENSITY OF FORCE AND POSITION, AND METHOD FOR MANUFACTURING AND USING THE SAME

摘要

PURPOSE: A contact resistance sensor for measuring contact force, contact resistance sensor for measuring contact force and contact position, a manufacturing method thereof and a method of using the sensor are provided to sense a wide area by decreasing the number of wires to be applied to a touch input instrument. CONSTITUTION: A contact resistance sensor for measuring contact force comprises a first substrate(100), a second substrate(110), a voltage-down resistance layer(130), a third signal line electrode(160), a first signal line electrode(140), a second signal line electrode(150), a dot spacer(170) and a gap spacer(175). The first substrate and the second substrate maintain a given gap(120) and are arranged in parallel to each other. The resistance of the voltage-down resistance layer changes according to a temperature or contact force. The third signal line electrode selectively receives a voltage signal, which is added to the voltage-down resistant layer. The first signal line electrode and the second signal line electrode selectively receive the voltage signal.
