Archivio Istituzionale della RicercaThis paper describes an extremely low-cost device for performing Electrochemical Impedance Spectroscopy (EIS) measurements. The proposed instrument is arranged by using a simple Teensyduino board and it does not require any additional analog amplifier. The instrument is capable of measuring impedance values which can span about three decades, in the frequency range from 0.01 Hz to 10000 Hz. The proposed measuring system can be inserted in a remote laboratory infrastructure so as to allow the user to assess the corrosion behavior of metals not only performing single measurements but also during in situ long term monitoring.

Abstract
This paper describes an extremely low-cost device for performing Electrochemical Impedance Spectroscopy (EIS) measurements. The proposed instrument is arranged by using a simple Teensyduino board and it does not require any additional analog amplifier. The instrument is capable of measuring impedance values which can span about three decades, in the frequency range from 0.01 Hz to 10000 Hz. The proposed measuring system can be inserted in a remote laboratory infrastructure so as to allow the user to assess the corrosion behavior of metals not only performing single measurements but also during in situ long term monitoring.
