Recently, our research group has proposed a MEMS-based solid state corrosion sensor based on the carbon black and metal particle polymer composite materials. The chemical and dimensional properties of the particles and polymer matrix will provide the tailorability in sensor sensitivity, selectivity, time response, and operating life-span. This paper will analyze the electrical resistivity of the sensor relative to the percentage of different type of particles in PDMS matrix in order to understand the effect of corrosion mechanism on metal particle polymer composites. This paper will also present the electrical quantification techniques for the micro corrosion sensors, the understanding of which is need for the transduction from corrosion to electronic output. Electronic transduction is the natural form of output due to the redox reactions of the electrochemical corrosion of particles and the electric current generated is directly proportional to the rate of the reaction.
