Abstract

The present invention uses a silver/silver chloride composition and ink jet technology in the art of digital printing, especially for use in blood glucose sensors.

Claims (12)

1. An ink jettable composition consisting of:

(i) a resulting solution consisting of sub-micron silver/silver chloride particles having a flake geometry polymeric binder; and a solvent capable of dispersing silver chloride and dissolving the polymeric binder wherein the polymeric binder is dissolved in the solvent; and

(ii) humectant to aid in ink jetting.

2. The ink jettable composition of claim 1 wherein the polymeric binder is present in the overall composition at about 1 to 4 wt. percent.

3. The ink jettable composition of claim 1 wherein the total silver/silver chloride is present at a concentration ranging from about 15% to 25%.

4. The ink jettable composition of claim 1 wherein the humectant is ethylene glycol.

5. The ink jettable composition of claim 1 wherein the humectant is present at a range of about 0.1% to 1%.

6. The ink jettable composition of claim 1 wherein the solvent is a dibasic acid.

7. The ink jettable composition of claim 1 wherein the silver/silver chloride ratio is 68/32 wt %.

8. The ink jettable composition of claim 1 wherein the silver/silver chloride ratio is 80/20 wt %.

9. The ink jettable composition of claim 1 wherein the silver/silver chloride ratio is 30/70 wt %.

10. The ink jettable composition of claim 1 wherein the silver/silver chloride ratio is from 90/10 to 10/90 wt %.
