Frequent determination of glucose concentrations in diabetic patients is required for diabetes management. This requires repetitive finger pricking. Use of non-invasive detection techniques offer several advantages, such as absence of pain, exposure to sharp objects and tighter control of glucose concentrations. These potential advantages have led to considerable interest in the commercialization of NI glucose monitoring devices. Several techniques have potential leading to viable measuring devices. One promising technique for monitoring blood glucose concentration is to use optical absorption spectroscopy. This project targets the detection of glucose concentration in blood using Infrared absorption spectroscopy, which will be amicable for Armed forces during critical conditions.

In order to measure blood glucose concentrations, the device involves the emission of near-infrared light and detecting absorbance of the light after it passes through specific glucose concentrations (like finger tip) measured in mg/dl or mmol/l. This project utilizes near-infrared light generated by light emitting diodes (LED) /lasers. Transmittance of the light through finger is analyzed by using a cooled MCT detector/Photo-diode. The light (frequency specific and intensity quantitative) absorbed is measure of presence of glucose, includes selection of light source, blood glucose spectroscopic absorption study, selection of detector and evaluation of design of a non-invasive diabetic sensor. Evaluation will be carried out using Electronic kits and programming to sense the glucose level and display.
