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.

Claims (30)

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.

19 . The RFID device of claim 12 wherein said brace material includes a moisture-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.
