Methods include functionalizing, into a compressible pressure varying electrical conductance device, a portion of a compressible nonwoven material (CNM) cushion. A process includes forming within a three-dimensional (3D) target region of the CNM cushion a columnar distribution of non-solidified conductive polymer, and converting the columnar distribution of non-solidified conductive polymer into a columnar compressible pressure varying electrical conductance structure. The columnar distribution of non-solidified conductive polymer extends along a column axis. Forming the columnar distribution includes injecting into at least a portion of the 3D target region a liquid carrying conductive polymer in suspension. The columnar compressible pressure varying electrical conductance structure includes mutually separated masses of solidified conductive polymer respectively supported by mutually separated flexible fibers of the compressible nonwoven material. Optionally, forming the columnar distribution of non-solidified conductive polymer includes a first injection followed by partial drying, and a second injection.
