A pressure sensing mat having first and second conductive layers and an insulative layer. The first conductive layer defines a first aperture and includes first spaced apart conductive regions and first non-conductive regions therebetween. The first spaced apart conductive regions and non-conductive regions extends in a first direction. The second conductive layer defines a second aperture and includes second spaced apart conductive regions and second non-conductive regions therebetween. The second spaced apart conductive regions and the second non-conductive regions extend in a second direction different than the first direction. The insulative layer is between the first and second conductive layers and defines a third aperture. The first, second, and third apertures are aligned with each other such that the first, second, and third apertures form a vent through the first and second conductive layers and the insulative layer.
