High precision system for bioimpedance measurement

Abstract

High precision system for bio-impedance analysis includes high-bandwidth low-noise amplifiers and high speed analog-to-digital converter for signal acquiring. The signal should be processed to extract useful information. This paper describes an effective system for bio-impedance processing in frequency domain with bandwidth up to 1MHz. The algorithm has been developed and tested in Institute for Bio-Medical-Physics for high-bandwidth multi-channel system for bioimpedance measurement equipment. Our motivation involves a bio-impedance measurement system for diagnostics of knee inflammation and other diseases.
