Abstract

A gas detection device is provided. The device includes a substrate and a dielectric material applied to the substrate. A sensor material is applied to the dielectric film. The sensor material has a bottom, a side, and a top surface. An electrode material is at least partially applied to the dielectric film and at least partially applied to a portion of the side of the sensor material and a portion of the top surface of the sensor material to pin a portion of the sensor material to the dielectric material. The electrode material forms a vapor barrier upon the sensor material to facilitate preventing delamination between the sensor material and the electrode material over portions of the sensor material where the sensor material is not pinned to the dielectric material.

Claims (32)

1. A gas detection device comprising:

a substrate;

a dielectric material applied to the substrate;

a sensor material applied to the dielectric film, wherein the sensor material has a bottom, a side, and a top surface;

an electrode material at least partially applied to the dielectric film and at least partially applied to a portion of the bottom of the sensor material, a portion of the side of the sensor material, and a portion of the top surface of the sensor material; and

an adhesion layer applied during a deposition process with the electrode material.

2. The gas detection device of claim 1 , wherein:

the electrode material at least partially applied to the dielectric film and at least partially applied to the portion of the bottom of the sensor material, the portion of the side of the sensor material, and the portion of the top surface of the sensor material is operable to pin a portion of the sensor material to the dielectric material, wherein the electrode material forms a vapor barrier upon the sensor material to facilitate preventing delamination between the sensor material and the electrode material over portions of the sensor material where the sensor material is not pinned to the dielectric material; and

the vapor barrier is formed by the electrode material on the portion of the bottom of the sensor material, the portion of the side of the sensor material, and the portion of the top surface of the sensor material where the electrode material is applied.

3. The gas detection device of claim 2 , wherein the electrode material substantially encloses portions of the sensor material which are not pinned to the dielectric layer, wherein the electrode material mitigates the volume expansion or contraction of the portions of the sensor material enclosed by the electrode material.

4. The gas detection device of claim 2 , wherein the electrode material is constructed and arranged to deform with the volume expansion or contraction of the sensor material without causing the delamination of the electrode material from the sensor material.

5. The gas detection device of claim 2 , wherein the electrode material is constructed and arranged to remain in contact with the sensor material during volume expansion or contraction of the sensor material.

6. The gas detection device of claim 2 , wherein at least a portion of the electrode material is positioned between the dielectric material and the sensor material.

7. The gas detection device of claim 2 , wherein the electrode material is formed without the use of water, water-based compounds, or saturating materials after the sensor material has been formed upon the substrate.

8. The gas detection device of claim 1 , wherein the adhesion layer is further applied without breaking a vacuum formed during the deposition process and without interrupting the deposition process.

9. A method of forming a gas detection device comprising:

applying a dielectric material to a substrate;

applying a sensor material to the dielectric film, wherein the sensor material has a bottom, a side, and a top surface;

at least partially applying an electrode material to the dielectric film and a portion of the bottom of the sensor material, a portion of the side of the sensor material, and a portion of the top surface of the sensor material; and

applying an adhesion layer during a deposition process with the electrode material.

10. The method of claim 9 , wherein:

applying the adhesion layer during the deposition process with the electrode materials to pin a portion of the sensor material to the dielectric material, wherein the electrode material forms a vapor barrier upon the sensor material to facilitate preventing delamination between the sensor material and the electrode material over portions of the sensor material where the sensor material is not pinned to the dielectric material; and

the method further comprises forming the vapor barrier with the electrode material on the portion of the bottom of the sensor material, the portion of the side of the sensor material, and the portion of the top surface of the sensor material where the electrode material is applied.

11. The method of claim 10 further comprising substantially enclosing, with the electrode material, portions of the sensor material which are not pinned to the dielectric layer, wherein the electrode material mitigates the volume expansion or contraction of the portions of the sensor material enclosed by the electrode material.

12. The method of claim 10 further comprising constructing and arranging the electrode material to deform with the volume expansion or contraction of the sensor material without causing the delamination of the electrode material from the sensor material.

13. The method of claim 10 further comprising constructing and arranging the electrode material to remain in contact with the sensor material during volume expansion or contraction of the sensor material.

14. The method of claim 10 further comprising positioning at least a portion of the electrode material between the dielectric material and the sensor material.

15. The method of claim 10 further comprising forming the electrode material without the use of water, water-based compounds, or saturating materials after the sensor material has been formed upon the substrate.

16. The method of claim 10 further comprising forming the electrode material in more than one deposition step.

17. The method of claim 10 further comprising forming at least one deposition of the electrode material after the deposition of the sensor material.

18. The method of claim 10 further comprising forming at least one deposition of the electrode material after the deposition of the sensor material without the use of water, water based compounds, or saturating materials.

19. The method of claim 9 further comprising applying the adhesion layer without breaking a vacuum formed during the deposition process and without interrupting the deposition process.
