Abstract

Current glucose monitoring devices are based on devices originally created in the 1960�s. They have been made smaller are easier to use and can log data, their measurements basically are the same as the first laboratory sensors. The patent must prick their finger so that they can squeeze a droplet of blood on a strip coated with an enzyme (usually glucose oxidase) that reacts to form hydrogen peroxide from the available glucose and oxygen. The hydrogen peroxide generated is then measured amperometrically with an electrode. The cost, inconvenience and pain incurred in using these systems have led to heavy research to develop non-invasive glucose monitoring techniques. The major current areas of research and the sensor technologies they use will be discussed. The techniques to be covered include interstitial fluid chemical analysis, breath chemical analysis, infrared spectroscopy, optical coherence tomography, temperature modulated localized reflectance, Raman spectroscopy, polarity changes, ultrasound, fluorescence, thermal spectroscopy, ocular spectroscopy and impedance spectroscopy.
