Abstract
An analytical element is disclosed for indicating concentration of a target analyte. The analytic element includes a transparent layer having a first side and a second side. A reactive layer faces the first side of the transparent layer. This reactive layer changes colorimetrically in response to concentration of the target analyte. A visually engineered layer is applied to the second side of the transparent layer so to form a display. A substantially linearly-varying signal displayed on the display is perceived by a user as a step-like signal.
Claims20
An analytical element for indicating concentration of a target analyte, comprising:
- a transparent layer having a first side and a viewing side;
- a reactive layer facing the first side of the transparent layer, said reactive layer changing colorimetrically in response to concentration of the target analyte;
- and
- a visually engineered layer applied to the second side of the transparent layer so as to form a display,
- a substantially linearly-varying signal displayed on the display is perceived by a user as a substantially step-like signal.
A method of making an analytical element for indicating concentration of a target analyte, the method comprising the steps of:
- providing a transparent layer having a first side and a viewing side;
- providing a reactive layer facing the first side of the transparent layer, said reactive layer changing colorimetrically in response to concentration of the target analyte;
- and
- applying a visually engineered layer to the second side of the transparent layer to form a display,
- such that a substantially linearly-varying signal displayed on the display is perceived by a user as a substantially step-like signal.
