Abstract :

This paper deals with study of the effect of input voltage variation on output response of bio-impedance measurement. During bio-impedance diagnosis output voltage differs as a function of function of input signal voltage variation. The accuracy of the diagnosis system depends on the exact value of voltage for which there is a wide variation in the output response. The proposed system implements voltage control signal generator circuit to study the output voltage variation and its impact on efficient design of invasive bio-impedance measurement applications. The system design has been implemented variable voltage signal generator IC, Isolation transformer, isolated & regulated power supply, Operational amplifier IC and Metal Surface electrodes.
