A method for sensing pressure in a pressurized article utilizing an electronic tag includes: calculating the impedance of a tag antenna, the tag antenna being flexible and at least partially composed of a flexible conductive pressure sensitive material including rubber; measuring changes in antenna impedance resulting from changes in pressure exerted on the tag antenna; calculating changes in tag transmission signal strength resulting from changes in antenna impedance; at least partially embedding the electronic tag within a wall portion of the article, the wall portion at least partially defining an article cavity and exerting a compressive force on the tag antenna of a magnitude determined by the magnitude of air pressure within the cavity; measuring the tag transmission signal strength with the tag antenna subjected to pressure from the article wall portion; determining the magnitude of air pressure within the cavity required to effect a compressive force on the tag antenna by the article wall sufficient to result in the measured tag transmission signal strength.
