Development of MATLAB Based Software for the Analysis of the Impedance Data Obtained from in-House Developed Bio-Impedance Analyzer

Abstract

Biological samples are sensitive to physical changes, mechanical as well as electrical. When any force is applied or temperature of the environment is increased or any torsion given to the system or electricity flows through it then it shows some changes behaviorally which in some distinguishable into eyes and is predictable. But there are two types of observations present which is taken into consideration. One is qualitative and other one is quantitative. Qualitative way is meant just to detect whether changes happening. But when it comes to comparison at that time one needs proof in which case this qualitative study fails. Again as biological samples are very sensitive to changes and different sample have different properties ,so they act differently in different time duration to the changes. Some changes such as due to electrical flow the changes in the behavior of the sample might not be visible but it can be predicted by the proposed method in quantitative approach. This study shows an easy approach to show the changes due to electrical current flow through the system. This quantitative approach also help in finding the stability as well as the utility of the model both in estimated and predicted cases. Here the well-known impulse response, Nyquist plot and Bode plot and the location of poles and zeros were used for detail analysis of the model behavior. Here hydrogel is taken as the dummy model for all the studies. This approach can be proposed in industrial way for samples stability prediction, its utility in required conditions and the productivity of the designed sample
