Analysis of stimulus by rfid

Abstract

The present invention is directed to an RFID device. The RFID device includes a brace affixed to an inductor. The brace is constructed from a material structurally responsive to a predetermined stimulus, such that stimulus-responsive structural alterations to the brace structurally alters the inductor, capacitor, or other RFID subcomponent of the RFID circuit capable of generating a current alteration, which in turn alters the signal frequency of the RFID.

1 . An RFID device comprising:
 an inductor with a voltage potential;   a conductive trace having an elastic connection with said inductor;   a deformable brace, positioned proximate to said inductor, constructed from a material structurally, selectively deformable in response to a predetermined external stimulus such that upon exposure to said stimulus said inductor flexes in concert with said brace to substantially alter said voltage potential; and   an antennae complex, in electrical communication with said inductor, initially adapted to accept a predetermined, base frequency and transmit a response signal, measurably distinct from said base frequency, based on said voltage potential.   
     
     
         2 . The RFID device of  claim 1  further comprising a substrate, and wherein said brace includes a brace carriage, contacting said substrate, housing at least a majority of said inductor. 
     
     
         3 . The RFID device of  claim 2  wherein said brace carriage houses an entirety of said inductor. 
     
     
         4 . The RFID device of  claim 2  wherein said brace carriage elevates said inductor from contact with said substrate. 
     
     
         6 . The RFID device of  claim 1  wherein said antenna complex includes a nested antenna complex, wherein said antenna strands are separated at a constant antenna separation distance value. 
     
     
         7 . The RFID device of  claim 1  wherein said antenna complex includes an antenna geometry with a substantially constant length and a substantially constant width. 
     
     
         8 . The RFID device of  claim 1  wherein said brace material includes a time decay material. 
     
     
         9 . The RFID device of  claim 1  wherein said brace material includes a temperature-sensitive material. 
     
     
         10 . The RFID device of  claim 1  wherein said brace material includes a moisture-sensitive material. 
     
     
         11 . The RFID device of  claim 1  wherein said brace includes a unidirectional brace. 
     
     
         12 . An RFID device comprising:
 a capacitor with a voltage potential, wherein said capacitor includes a first electrode; a second electrode; an insulator, positioned between said first electrode and said second electrode, composed of a dielectric material;   a conductive trace having an elastic connection with said capacitor;   a deformable brace, positioned proximate to said capacitor insulator, constructed from a material structurally, selectively deformable in response to a predetermined, external stimulus such that upon exposure to said stimulus said capacitor flexes in concert with said brace to substantially alter said voltage; potential by dislocating said first capacitor from said second capacitor; and   an antennae complex, in electrical communication with said capacitor, initially adapted to accept a predetermined, base frequency and transmit a response signal, measurably distinct from said base frequency, based on said voltage potential.

         15 . (canceled) 
     
     
         16 . The RFID device of  claim 12  wherein said antenna complex includes an antenna geometry with a substantially constant length and a substantially constant width. 
     
     
         17 . The RFID device of  claim 12  wherein said brace material includes a time decay material. 
     
     
         18 . The RFID device of  claim 12  wherein said brace material includes a temperature-sensitive material.

         20 . An RFID device comprising:
 a circuit, comprising a series of RFID subcomponents interconnected via a conductive trace, forming a current pathway;   a deformable brace, distinct from and positioned proximate to said circuit outside of said current pathway, constructed from a material structurally, selectively deformable in response to a predetermined external stimulus such that upon exposure to said stimulus said brace flexes to contort said circuit to substantially alter a voltage potential across said circuit;   an antennae complex, in electrical communication with said circuit, initially adapted to accept a predetermined, base frequency and transmit a response signal, measurably distinct from said base frequency, based on said altered voltage potential.
