Abstract
A non-invasive biomedical sensor for monitoring glucose levels is described. The sensor utilizes laser light to determine glucose levels in urine, but could also be used for drug screening and diagnosis of other medical conditions. The glucose measurement is based on modulation spectroscopy with harmonic analysis. Active signal processing and filtering are used to increase the signal-to-noise ratio and decreases the measurement time to allow for real time sample analysis. Preliminary data are given which show the concentration of glucose in a control sample. Future applications of this technology, for example, as a portable multipurpose bio-medical analysis tool, are explored.
