Electrochemical Sensors
Materials for batteries and high temperature have become increasingly important to industry and consumers since the introduction of the Clark oxygen sensor in the 1950s. Amperometry can perform both quantitative and qualitative analysis for a variety of energy-related chemicals and pollutants. Besides investigations into fundamental sensor mechanisms and the theory of sensor operation, a key focus of electrochemical sensor research is on applications and technology development, including low-cost manufacturing technology, high analytical performance and rugged field packaging. These technologies form the heart of a unique sensor capability at IIT in the areas of the environment, fuel cells, and automotive and power generation.
Specific sensors of interest include those for CO, H2, oxygen, combustion gases and products, fuel cell feed materials, SO2, NO, NO2, O3 and other electroactive compounds. Combining sensors into arrays with artificial neural networks allows the investigation of smart sensors (or electronic noses) that are portable and capable of solving complex analytical problems.
