The surface acoustic wave touch screen works by to two transmitters and two receivers, one for each axis. The signal in the form of a wave is routed through reflectors to the surface of the glass creating a lattice, the touch determines a variation, with consequent calculation of position by the controller.
The thickness of the glass does not interfere with the measure because it is surface waves. It is possible get this kind of touch even with curved glasses. We supply SAW surface acoustic wave touchscreens with Beetouch.
