This paper presents basic principle of bioimpedance along with its application for blood glucose analysis and effect of frequency on impedance measurement. This thesis gives a description of a prototype bioimpedance measurement system based on the integrated circuit AD5933. It is powered by the Analog Devices AD5933, a high precision impedance converter system solution that combines an on-board frequency generator with a 12-bit. The following figure shows one of the most effective decoupling techniques, which uses two parallel capacitors. Hannas has much experience of technological processes, Piezo Hannas reliably meets customer customization demands and reacts quickly to the market’s requirements. The AD5933 is a high precision impedance converter system solution that combines an on-board frequency generator with a 12-bit, 1 MSPS, analog-to-digital converter (ADC).
