Abstract

Diabetic patients are generally advised to check their blood glucose level 5to 7 times per day. Since the all current existing conventional methods of home blood glucose tests are painful, intimidating, laborious, and expensive, since they require obtaining a blood sample by pricking a fingertip with a needle or lancet. Thus it is necessary to develop a non-invasive blood glucose method which could provide fast, painless, and convenient glucose monitoring to diabetic patients. Since a noninvasive method of monitoring blood glucose would present major advantages over current existing methods which are using invasive technologies. This project presents a noninvasive technique for bioelectrical resistivity applying current pulse technique and curve fitting method. Simple circuit for current injection and voltage detection, circuit requires four electrodes two to current injection and two to voltage detection. The current source is presented with constant output current as low as 5.5mA. The voltage signal amplified and filtered to be used on microcontroller. The Voltage detection and calculate of blood glucose from curve fitting technique(formulate equation using Mat lab). Successful simulation results using protus8 program.
