Abstract
The suitability of a new impedance analyzer 'INPHAZE' for bio-impedance and Electrical Impedance Tomography (EIT) is investigated using measurements on simple resistive and capacitive models, and readily available biological objects. The INPHAZE is an impedance spectrometer developed to measure the impedance of thin films and layers but has been used in various applications. We found that it is superior to the UCL mk2.5 EIT system on measurements of resistive models and biological objects; however it is significantly over 10x slower as with each measurement checked for stability and SNR. We suggest that the device may provide significant improvements for bio-impedance. However for EIT we suggest exploration of expansion to more channels and the effect of reducing measurement times.
