Abstract:
This paper presents a low cost and portable system that is able to perform real time or spectra impedance characterization of impedimetric sensors interfaces. It is also able to perform simple amperometric measurements for real-time DC current-voltage characterization or studies of the behavior of the sensor with respect to different target stimuli. Due to its flexible design, the system can be easily adapted to different applications and experimental requirements. Synthetic devices under test (DUTs) were used for testing purposes and the performances have been compared to those obtained using a commercial dedicated impedance analyzer. The system allows displaying results in Nyquist and Bode plots using a friendly graphical user interface. Results show remarkable fair accuracy, considering the much lower price, smaller sizes and flexibility of use of the developed system.
