Abstract

A bioindicator assembly for determining a level of CO2 in a surrounding environment includes an article and a bioindicator component applied to the article. The bioindicator component includes a composite fabric that has a substrate, wherein a biodegradable material is applied to the substrate, a membrane that is coupled with the composite fabric to define an interior cavity, the membrane being semi-permeable, a bioindicator that changes color, form, shape, or texture when exposed to CO2, and an attachment mechanism coupled to a rear side of the composite fabric.

First claim

We claim:

1. A bioindicator component for determining a level of CO 2 in a surrounding environment, comprising:
a composite fabric that includes a substrate, wherein a biodegradable material is applied to the substrate;
a membrane that is coupled with the composite fabric to define an interior cavity, the membrane being semi-permeable;
a bioindicator that changes color, form, shape, or texture when exposed to CO 2 ; and
an attachment mechanism coupled to a rear side of the composite fabric.

2. The bioindicator component of claim 1 , wherein the substrate is in the shape of a circle.

3. The bioindicator component of claim 2 , wherein the attachment mechanism comprises hooks.

4. The bioindicator component of claim 1 , wherein the bioindicator changes color when exposed to CO 2 .

5. The bioindicator component of claim 1 , wherein the bioindicator comprises an algae.

6. The bioindicator component of claim 5 , wherein the algae is of the type oscillatoria.

7. The bioindicator component of claim 5 , wherein when the bioindicator component is exposed to a threshold level of CO 2 , the bioindicator component turns purple.

8. A bioindicator assembly for determining a level of CO 2 in a surrounding environment, comprising:
an article; and
a bioindicator component applied to the article, the bioindicator component comprising:
a composite fabric that includes a substrate, wherein a biodegradable material is applied to the substrate;
a membrane that is coupled with the composite fabric to define an interior cavity, the membrane being semi-permeable;
a bioindicator that changes color, form, shape, or texture when exposed to CO 2 ; and
an attachment mechanism coupled to a side of the composite fabric.

9. The bioindicator component of claim 8 , wherein the article is an article of clothing.

10. The bioindicator component of claim 8 , wherein the article is an article of footwear.

11. The bioindicator component of claim 8 , wherein the bioindicator comprises an algae that changes color when exposed to CO 2 .

12. The bioindicator component of claim 11 , wherein the algae is of the type oscillatoria.

13. The bioindicator component of claim 12 , wherein when the bioindicator component is exposed to a threshold level of CO 2 , the bioindicator component turns a different color.

14. A method of utilizing a bioindicator assembly that can determine a threshold level of CO 2 in a surrounding environment, comprising:
removing a bioindicator component from a pouch, the bioindicator component comprising:
a composite fabric that includes a substrate, wherein a biodegradable material is applied to the substrate,
a membrane that is coupled with the composite fabric to define an interior cavity, the membrane being semi-permeable,
a bioindicator that changes color, form, shape, or texture when exposed to CO 2 , and
an attachment mechanism coupled to a rear side of the composite fabric;

applying the bioindicator component to an article via the attachment mechanism along the bioindicator component.

15. The method of claim 14 , wherein the article is an article of clothing.

16. The method of claim 14 , wherein the article is an article of footwear.

17. The method of claim 14 , wherein the bioindicator comprises an algae that changes color when exposed to CO 2 .

18. The method of claim 17 , wherein the algae is of the type oscillatoria.

19. The method of claim 14 , wherein when the bioindicator component is exposed to a threshold level of CO 2 , the bioindicator component turns a different color.

20. The bioindicator of claim 14 , wherein the attachment mechanism comprises a hook and loop structure.
