Abstract
Methods and apparatus are provided for a transparent and flexible pressure-sensing touch panel. The touch panel includes a flexible and substantially transparent composite layer (e.g., a plurality of conductive particles within a polymeric matrix) such that the resistivity of the composite layer is a function of applied force, and such that the touch panel may be manipulated to conform to a non-planar surface, such as a non-planar display screen.
