Abstract
A pressure sensing system (), seat cushion () incorporating the pressure sensing system, and method of sensing a weight group associated with an occupant of an automotive seat are described. The pressure sensing system includes a layer of an electrically conductive foam () and a flexible printed circuit () that includes a flexible substrate () and N horizontal sensing wires () and M vertical sensing wires () securely placed on a top surface of the flexible substrate. The horizontal sensing wires intersect with the vertical sensing wires and form N×M intersections. The layer of an electrically conductive foam is placed on top of the N horizontal sensing wires and the M vertical sensing wires. When a pressure is applied to the layer of the electrically conductive foam, each intersection generates in real time an electric flux density value to reflect a degree of a compression caused by the pressure to a corresponding point of the electrically conductive foam.
