Abstract: A laminated acoustic wave touch panel is shown and a method of making the panel is described using an adhesive barrier material. The adhesive barrier material is positioned between a substrate in which a shear wave is to propagate and a backplate in order to form a cavity between the substrate and backplate. An adhesive is injected into the cavity to laminate the substrate to the back plate. The use of the barrier material allows the laminated touch panel to be easily manufactured and allows the adhesive to be constrained to a desired area of the panel. The invention envisions the use of similar and dissimilar materials for the substrate and backplate. The velocity of a shear wave at a given frequency is greater in the backplate than in the substrate in the case where the materials are dissimilar and equal for a given frequency when the materials are the same.
