Matrix Resistive

Sensor Materials

Glass or Acrylic substrate, Spacer dots, Polyester sheet(s), ITO Film

Principle of Operation

  • A touch compresses the flexible Top layer into contact with the bottom glass layer.
  • A voltage gradient is applied to the top and bottom layer (X and Y axis) of each row and column sequentially.
  • The controller calculates the X and Y position of the touch or touches based on the voltage gradient applied to one side of the node and using the opposite side of the node as a voltage probe.


  • Full Multi-touch capabilities including advanced gestures
  • Low Cost
  • Stylus Independence
  • Multi-user collaboration potential


  • PET top sheet is highly susceptible to scratches, cuts and cigarette burns
  • PET layer is a flexing mechanical element coated with a conductive ceramic which wears with every flex
  • Transmission typically in 80% to 85%
