Title: Non-contact monitoring of biofilms and corrosion on submerged surfaces with electrochemical impedance spectroscopy

Abstract

Systems and methods for monitoring microorganisms on a surface are provided. In particular, a flat, patterned sensing electrode can be positioned proximate a surface in non-contact relationship with the surface. The sensing electrode can include a working electrode and a counter electrode. The surface and the sensing electrode can be submerged in an aqueous medium. An alternating current signal can be applied at the working electrode. The signal can propagate through the aqueous medium and can be measured at the counter electrode. The presence of microorganisms on the surface can cause changes in the signal as the signal propagates through the aqueous medium. Such changes in the signal can be used to determine impedance parameters, which can correspond to microbial characteristics associated with the surface. For instance, the microbial characteristics can be associated with a biofilm, corrosion and/or bio-corrosion on the surface.
