MD-SAW, Surface Acoustic Wave - How it Works

A known sound wave is transmitted along both axes of the glass surface. When the finger or pen makes contact with the screen the sound wave is attenuated. Speed of sound is constant so time is used to determine the location of the attenuation in both the X and Y Axis

Simple transducers on a glass surface means that there is nothing to wear out.
