A fabric-based pressure sensor array includes:(1) a first layer including M elongated conductive strips coated thereon;(2) a second layer including N elongated conductive strips coated thereon, the M elongated conductive strips extending crosswise relative to the N elongated conductive strips to define M× N intersections; and (3) a unitary textile sheet extending between the first layer and the second layer so as to overlap the M× N intersections, the textile sheet having a variable resistivity in response to applied pressure so as to define M× N pressure sensors at locations corresponding to the M× N intersections.
