Claim Text:
1. A radio frequency identification (RFID)-enabled pressure sensing apparatus, comprising: a plurality of RFID tags attached to an operatively insulating and compressible substrate; a collector in communication with the plurality of RFID tags; an operably planar open waveguide, the waveguide being bonded on an operatively insulating dielectric base and in communication with the collector; and a load connected to one end of the waveguide, wherein the substrate having the plurality of RFID tags attached thereto is positioned over the dielectric base and adjacent to the waveguide, one or more of the plurality of RFID tags being energized when operably depressed to enable an electromagnetic coupling between the waveguide, allowing the operably depressed RFID tag to send signals via the collector to an interrogator.
