Abstract

This paper presents a solution for detecting degradation in electrodes that interface to fluidic or biological systems that forms the basis of numerous actuation and sensing mechanisms in the bio-fluidics field. In this solution, a mid-frequency oscillation test strategy is proposed and evaluated experimentally on an array of electrodes. This technique is based on the sensitivity of the bio-fluidic interface capacitance to degradation, contamination and fouling.
