Development of a Bi-Polar Impedance Based Sensor System and LabView Based Software for Analyzing Analytes for Probable Applications in Biomedical Engineering

Abstract

The application of Electrochemical Impedance Spectroscopy (EIS) in the field of biomedical engineering is not well known. In this research, an effort is being made to analyze electrical properties of saline solution. For this purpose aluminum thin film electrodes of different electrode spacing were fabricated. The electrical equivalent models were used to analyze the complex processes taking place at the electrode-electrolyte interface by varying the spacing and concentration of sample. The software for stability analysis was developed using LabVIEW. Most stable combinations of model and electrode were carefully selected using time and frequency domain parameters
