Mechanical modeling and simulation of optical wave guide for touch sensor application

Abstract

Touch screen monitors have become more and more used in commonplace. There are several different touch sensor technologies available in the market today, each using a different method to detect the touch input or the location of the disturbance experienced by a force exerted by the touch. There are three basic systems that are used to recognize a person's touch which are resistive, capacitive and surface acoustic wave. The sensing of a disturbance to a signal carrying medium can also be easily and efficiently captured by optical sensors also as well.
