1. A method of determining a physiological characteristic, comprising the steps of:
- providing at least one physiological sensor that is adapted to measure at least one physiological characteristic at a target measurement site on a subject'"'"'s body;
disposing said physiological sensor proximate said target measurement site on said subject'"'"'s body;
heating a tissue region on said subject'"'"'s body, whereby blood perfusion of said tissue region is enhanced, said tissue region including said target measurement site and extending beyond said target measurement site; and
measuring at least one physiological physiological characteristic at said target measurement site with said physiological sensor during or within a predetermined period after said heating of said tissue region.

Abstract
A non-invasive method of determining a physiological characteristic, comprising providing at least one physiological sensor that is adapted to measure at least one physiological characteristic at a target measurement site on a subject'"'"'s body, heating an extended tissue region on the subject'"'"'s body, whereby blood perfusion of the tissue region is enhanced, and measuring at least one physiological characteristic with the physiological sensor during or within a predetermined period after heating the extended tissue region.

7. A method of determining a physiological characteristic, comprising the steps of:
-
providing a plurality of physiological sensors that are adapted to measure at least one physiological characteristic at target measurement sites on a subject'"'"'s body; disposing a first physiological sensor proximate a first target measurement site on said subject'"'"'s body; disposing a second physiological sensor proximate a second target measurement site on said subject'"'"'s body; heating a first tissue region on said subject'"'"'s body, whereby blood perfusion of said first tissue region is enhanced, said first tissue region including said first target measurement site and extending beyond said first target measurement site; and measuring at least one physiological characteristic with said first and second physiological sensors during or within a predetermined period after said heating of said first tissue region. - View Dependent Claims (8, 9, 10, 11, 12)
