Short description: It is commonly known that being vaccinated is unpleasant. Diabetic patients must perish uncomfortable injections transdermally through the skin multiple times a day in order to determine their individual blood glucose level. These measurements are annoying and painful. Doesn’t any reliably solid, non-invasive alternative for blood glucose monitoring exist? We follow the basic concept of thought that the blood glucose level can be determined by means of the light absorption properties of the glucose in the blood. Initially we examined the miscellaneous optical characteristics of different substances (pork blood, sugar water etc.) with the aid of a photometer. We came to the conclusion, that a LED in a near infrared range is mandatory. Being partially absorbed by the finger skin, the residual light can be measured by a photodiode which is positioned on the opposite side of the finger. Consequently the blood glucose level is being determined noninvasively by measuring the residual light. Calculating with a conversion factor, the measurement accuracy of the noninvasive new solution is being ascertained by comparing the results with conventional invasive methods.
