A1.3 - Electrical Impedance Spectroscopy Combined with Temperature Cycled Operation for Semiconductor Gas Sensors

A. Schütze, G. Reimann, S. Darsch, M. Schüler & T. Gillen
Applications like fuel cells, batteries or food analysis are typical fields of interest for electrical impedance spectroscopy (EIS). Another field with promising results are EIS measurements in semiconductor (sc) gas sensor applications. Due to their high sensitivity and low cost, sc gas sensors are ideally suited for different applications, especially in the field of safety and security. The major drawbacks of sc gas sensors, i.e. poor selectivity and sensor baseline drift, can be overcome by...
