Abstract
A capacitive detection system including an upper electrode printed on an upper film layer and a lower electrode printed on a lower film layer. The system includes a plurality of nodes of dielectric material printed in a spaced apart pattern on the lower film layer. The upper film layer is positioned over the lower film layer so that when a downward force is applied to the upper film layer the distance between at least a portion of the upper conductor and the lower conductor decreases. The system includes a controller operatively connected to the upper and lower electrodes. The controller includes a sensing circuit or processor configured to detect the presence of the occupant using a measure of the capacitance between the upper and lower electrode.
