Design, implementation and test of a fast impedance spectroscopy measurement system for biomedical applications

Abstract

This project offers a detailed explanation on the design, implementation, and measures to characterize the hardware and firmware programmed for the acquisition of the electrical impedance spectra. It includes from the signal generation, which is based on the use of a multifrequency signal, to the acquisition and signal processing. All have been implemented using the development board RedPitaya. Moreover, all the process of signal generation, signal acquisition and processing so as the results calculation is done inside the commented RedPitaya board. The communication between the board and the computer is handled through SSH via ethernet port. Finally, this project also includes a brief script implemented in MatLab which objective is just to represent the acquired results from the board. To conclude, characterization measures are made to verify the system specifications.
