Electrical impedance measurement is very important in characterization process of sensors and new materials. Application of commercial measuring devices in different laboratory analysis is often, because these devices/instruments usually have excellent accuracy and reliability. However, development of measurement devices for in-situ measuring is very important, because of limitations of impedance analyzers related to the dimensions, complexity and price. In this paper, we present theoretical background for design and development of portable and compact electronic device for complex impedance measurement. Our approach consists of generation of the reference AC voltage, which will cause flow of electrical current through the device under test (DUT), and processing of the voltage across of the DUT with Discrete Fourier Transformation (DFT). Hardware prototype of the measurement system based on the proposed approach has been developed. Experimental verification and comparison with commercial impedance measurement systems determined the measurement accuracy of the developed device. | URI: | https://open.uns.ac.rs/handle/123456789/2354 | ISBN: | 9781538639740 | DOI: | 10.1109/ECCTD.2017.8093360 |
