Abstract
Systems and related methods providing for touch sensors using high sensitivity Lamb waves are disclosed herein. A touch apparatus may include a substrate having a front surface and a back surface, where the touch region is on the front surface. The touch apparatus may be configured to propagate surface acoustic waves on at least a portion of the back surface and high sensitivity lamb waves, such as near-longitudinal-resonance Lamb waves, in at least a portion of the touch region of the substrate. The touch system may further include circuitry configured to determine a location of a touch on the front surface based on received attenuations in the high sensitivity Lamb waves. Some embodiments may provide for bezel-less touch sensor designs and anti-dispersion techniques that enhance touch sensor reliability.
