Multi-layer pad and methods of using the same
First Claim
1. A multi-layer pad adapted to be used in determining an analyte concentration, the pad comprising:
- a first layer including an enzyme, the first layer comprising material selected from the group consisting of fabric, porous membrane, and paper material, the enzyme being adapted to assist in determining the analyte concentration; and
a second layer being chemically cross-linked to the first layer, the second layer being made of a skin-conforming material.

Abstract
A multi-layer pad that is adapted to be used in determining an analyte concentration is disclosed. The multi-layer pad includes a first layer, a second layer, and a third layer. The first layer includes an enzyme wherein the enzyme is adapted to assist in determining the analyte concentration. The second layer is attached to a first surface of the first layer. The second layer is made of a skin-conforming material. The third layer is attached to a second surface of the first layer wherein the first layer is located between the second layer and the third layer. It is contemplated that the multi-layer pad may also be a two layer system.
