An Electrical Impedance Tomography Platform for Tissue Engineering

Electrical Impedance Tomography (EIT) stands out as a promising imaging tool designed for probing the electrical characteristics of tissues, including those within the human body. The affordability, non-invasiveness, and portability of EIT have contributed to its widespread adoption in numerous biomedical applications. However, the effective implementation of EIT demands substantial advancements in both hardware and software domains. Moreover, customization is necessary for every EIT system to suit the specific application of interest. In this paper, an efficient EIT hardware suitable for tissue engineering applications is presented. This analysis focuses on the initial assessment of the system's functionality. In the initial stage, this involves comparing data obtained from simulations with experimental data acquired using resistive mesh phantoms. Subsequently, the validation procedure is further performed by executing the reconstruction of an inclusion within a specially designated tank that has been filled with a saline solution. The system has demonstrated the potential to be employed for future studies as a label-free system for the non-destructive characterization of complex biological processes.
