Abstract
This thesis gives a description of a prototype bioimpedance measurement

system based on the integrated circuit AD5933. The prototype operates

from 5 - 100 kHz and covers the impedance range 0.1k

- 10 M

in six

subranges.

The system is operated from a PC, and the software required for

operation and control has been developed.

Verification testing on R/C modules have shown that the calibration

process and the signal level are critical issues with regard to operational

performance. With carefull calibration the system operates well and whole

body measurements on 11 persons have been performed with satisfactory

and repeatable results. Statistical processing of the results using both a

Standard Deviation approach and a Principal Components Analysis gave

results identifying regions of whole body impedance values as well as

indicators for outliers.

The measurement principle as such is very promising and with a

promised updating of the IC the applicability will improve.
