1. A pressure pad, comprising:
a footprint comprising:
an elliptical or polygonal outline; and
an orifice within the elliptical or polygonal outline;
a gasket;
a controller;
a first pressure-sensing fabric, wherein the first pressure-sensing fabric is in mechanical communication with the gasket, and in electronic communication with the controller, and comprises:
a flexible, extensible, and elastic support;
a plurality of primary tracks comprising extensible and elastic conductive ink or paste which is printed on the support;
a plurality of secondary tracks comprising extensible and elastic conductive ink or paste which is printed on the support;
a plurality of piezoresistive ink or paste depositions disposed on the plurality of primary tracks, wherein each of the plurality of piezoresistive ink or paste depositions acts as a pressure-sensing point, wherein each of the plurality of piezoresistive ink or paste depositions is in connection with a secondary track;
wherein the primary and secondary tracts are in electronic connection with the controller without crossing each other; and
wherein the controller comprises a memory, and non-transitory computer-readable medium which stores instructions for integrating a plurality of pressure measurements collected by the plurality of pressure-sensing points to compile a distribution of pressure on the pressure pad; and
wherein the gasket further comprises an inner edge of the gasket which defines an orifice, and which extends further toward a center point of the orifice than the first pressure-sensing fabric, and which houses wires which are in electronic communication with the first pressure-sensing fabric.
