Abstract

A method for manufacturing an analytical test strip with an electroluminescent component (either an electroluminescent module and/or an electroluminescent lamp) includes sequentially applying to a substrate layer, a rear electrode layer disposed on the substrate layer, an electrically-insulating layer disposed over the rear electrode layer, a phosphor layer disposed over the electrically insulating layer, and a front electrode layer (at least a portion of which is translucent) disposed over the phosphor layer. The sequential application is accomplished such that it forms an electroluminescent component of the analytical test strip.

Claims

1. A method for manufacturing an analytical test strip with an electroluminescent component, the method comprising:

applying, in a sequential manner, to a substrate layer of an analytical test strip;

a rear electrode layer;

an electrically-insulating layer disposed over the rear electrode layer;

a phosphor layer disposed over the electrically insulating layer; and

a front electrode layer, at least a portion of which is translucent, disposed over the phosphor layer, thereby forming an electroluminescent component of the analytical test strip.

2. The method of claim 1 wherein the applying step further applies an encapsulant layer disposed over the front electrode layer.

3. The method of claim 2 wherein the encapsulant layer includes a wavelength modulator.

4. The method of claim 1 wherein the applying step is conducted using continuous web-printing techniques.

5. The method of claim 1 wherein the applying step is conducted using flat-bed printing techniques.

6. The method of claim 1 wherein the applying step is conducted using a combination of flat-bed and web-based continuous printing technologies.

7. The method of claim 1 wherein a drying occurs intermittently during the applying step.

8. The method of claim 1 wherein the electroluminescent component is an electroluminescent module configured to emit light that facilitates a fluorescent chemical reaction sequence involving a fluorophore-containing photometric enzymatic reagent of the analytical test strip and the analyte.

9. The method of claim 1 wherein the electroluminescent component is an electroluminescent lamp configured to emit light that provides spatial awareness to a user.
