Reliable touch detection provides extremely high sensitivity with very low capacitance measurement resolution, offering a highly accurate and robust solution.
RIBA-II accomplishes this task using newly-developed Smart Rubber sensors (Table 1, Figure 2, 3), the first capacitance-type tactile sensors made entirely of rubber.
The planar cell structure integrated a Hi-K (high capacitance) metal gate stack into the NAND production to allow for smaller floating gates and thus higher storage capacity.
