Abstract
A touch sensor system, including a substrate, capable of propagating surface acoustic waves; and a reflective array formed on said substrate, said reflective array having a plurality of reflective elements, each reflective element reflecting a portion of an incident surface acoustic wave. The reflective array is formed of an organic matrix. The organic matrix is preferably chemically bonded to the substrate, and is preferably a thermoset resin. The resulting reflective arrays are preferably stable under changes in moisture between 0% and 60% RH at temperatures between about 0.degree.-50.degree. C. The organic matrix can also be used in a humidity or chemical sensor.
