ABSTRACT:
The present invention is directed to a touch panel for use in a touch position sensor. The touch panel includes a substrate fabricated at least partially from plastic materials. The plastic may be a polystyrene and/or copolymers of polystyrene. The touch panel utilizes transverse acoustic waves having a frequency in the range of 0.2 to 2.0 Megahertz to detect a touch on the touch panel.
