Development of low cost bioimpedance analyser for analysing various biological samples

Impedance analysis of the biological event has gained much importance in recent years. In this study, an attempt was made to develop a low-cost impedance analyser for the measurement of bioimpedance. 8038 IC was used as a waveform generator for the analyzer. The impedance analyzer was interfaced with PC using NI 6009. The developed analyzer was functional in the frequency range of 100 Hz-5 KHz. The measurement of bioimpedance of goat blood suggested a decrease in the impedance of the blood with dilution.
