A Review Paper on the Sensitivity Analysis in Bioimpedance Measurement Technique

Bioimpedance is one of the most modern measurements of human body which is very essential in analyzing different biological system. Sensitivity analysis is very important in measuring the bioimpedance. Comsol Multi physics software simulations that use finite element method plays a very important role in analyzing the sensitivity. Also Matlab was used in some cases with Comsol to show the 3D representation of sensitivity. Proper sensitivity analysis helps us predict contribution of any the change of conductivity within active. This paper is mainly focused on simulation that has been done so far in analyzing the sensitivity of the region of interest. This review paper shows the sensitivity for different configuration of electrodes- TPIM, 4 electrodes FIM, 6 electrode FIM, 8 electrode FIM. It also shows the sensitivity of the most recent configuration of electrodes where electrodes are placed on back and forth which enhance the sensitivity at the central region that is very important to measure the change of impedance for deep organ inside the body.
