Design and Implementation System for Serum Glucose Estimation

Abstract

Blood glucose monitoring is a way used for testing the concentration of glucose in the blood (glycemia). Practically important to measure the levels of blood glucose in the care of diabetes mellitus patients. A blood glucose test is performed by piercing the skin (typically on the finger) to draw blood, then applying the blood to a chemically active disposable "test stripe".
The main idea for the design of the circuit is by using a variable capacitor consist of two passive terminal or plates and by changing the density of the insulator between the two plates of the capacitor. The changing in capacitance results of the capacitor which is a part of a (frequency generator circuit) for that the output frequency of the circuit will be change, and if we used that frequency as an input to counter circuit we can read out the concentration of the glucose in the sample and then we display the result on a LCD monitor. The present study includes a comparison between the present system and the conventional glucose serums measurement systems, and the result approximately the same.
