Abstract:
A touch sensor may include a digital resistive touch (DRT) sensor architecture that is substantially free of air gaps. The DRT touch sensor may include a layer of force-sensitive resistor (FSR) material on an array of row and column electrodes. The electrodes may be formed on a substantially transparent substrate. Near the intersection of each row and column, one or more thin transparent patterned conductive bridges may be situated above the FSR. The conductive bridges may be configured for electrical connection with row and column electrodes when force is applied to the conductive bridge or surface of the touch sensor. Some touch sensors may include both DRT and projected capacitive touch (PCT) functionality.
