摘要: The AD5933 [1], a specialized single chip impedance analyzer, made by Analog Devices, is basically not intended for use with four electrode interface. Due to electrochemical phenomena at the electrodes connecting material under test (MUT), especially in low frequency region below 100 kHz, two interface generates considerable errors during measurement. Thus, most application bio-impedance measurement only can guarantee reliable results. Here we show how galvanostatic excitation but also potentiostatic be realized just few external components.
