Abstract
In this paper we introduce a new multi-channel system for measuring electrical impedance of biological tissues. This 4-channel impedance measurement system was designed to achieve high sensitivity, high resolution, good stability and safety for medical applications. The system consists of a sine-wave oscillator, an 16X4 multiplexer, a voltage control current source, an instrumentation amplifier, a band pass filter, a detector, a low pass filter, an isolation amplifier and an A/D converter. Results of some experiments with the resistance box have been shown that we have obtained a bio-impedance measurement system with high sensitivity, high resolution, good stability and safety for medical applications.
