An integrated device for non-invasive analyte measurement is described
herein. In typical operation, the glucose measurement device is
self-normalizing in that it does not employ an independent reference
sample in its operation. The device uses attenuated total reflection
(ATR) infrared spectroscopy for glucose measurement from the user's skin
surface. The device also includes a pressure and/or user identification
sensor(s) to ensure that an authorized user is utilizing the device. The
identification sensor may utilize capacitive or infrared detection of
biometric identification features, such as fingerprints, for comparison
to a stored value indicative of an authorized user. The device may be
configured such that verification of a user's identity may be a
prerequisite to use and/or activation of the device.
