MOBILE ANALYTE MONITORING SYSTEM
First Claim
1. An analyte monitoring system, comprising:
- an analyte sensor having a base and an analyte reagent system coupled to the base, wherein the analyte sensor is configured to exhibit a reversible color change in response to a target analyte; and
a reader device configured to capture an image of the analyte sensor and determine a concentration of the target analyte based at least on the image.

Abstract
A mobile analyte monitoring system may include an implantable sensor and a reader device with an optical sensor. The implantable sensor may be implanted into the dermis of an animal, and may exhibit a color change in response to the presence of a target analyte or reaction product thereof. The reader device may be configured to capture an image of the implanted sensor and to determine the concentration of the target analyte based at least in part on the image. One or more portions of the implantable sensor or components thereof may be configured to facilitate calibration of the sensor, correction of an optical signal obtained from the sensor by a reader device to accommodate variations in the surrounding tissues, and/or calculation of a representative value by a reader device. The reader device may be a personal electronic device such as a cell phone, PDA, or personal computer.

16. A method of monitoring an analyte sensor implanted in the dermis of a subject, wherein the implanted analyte sensor includes one or more analysis regions configured to exhibit a reversible color change in response to a change in concentration of a target analyte, the computer-implemented method comprising:
-
receiving first image data representative of a first image of the implanted analyte sensor; determining, based at least on the first image data, a first color value corresponding to a portion of the one or more analysis regions; and determining a concentration of the target analyte based at least on the first color value. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 33, 34)
