ABSTRACT:
The present invention is directed to a multilayer substrate for use in touchscreen and touch sensor applications. The substrate, including a microsheet, a polymer sheet, and a plate supports the propagation of acoustic waves, including Love waves and Rayleigh-like waves. The microsheet and plate may be fabricated from glass, metal, or other suitable materials depending on the desired application for the touchscreen. The polymer sheet may be fabricated from polystyrene, polyacrylates, polyether sulfones, or polycyclic olefins. The disclosed touchscreen substrates are thin but durable and have increased touch sensitivity with decreased sensitivity to water and other surface contaminants.
