Impedance Spectroscopy Laboratory

Cook Hall, 3072
Laboratory Director: Derk Joester, MSE

This laboratory houses Agilent Technologies 4192A and Solartron 1260 impedance analyzers, fully computer-controlled, for performing frequency-dependent impedance/dielectric spectroscopy studies of materials. Recent materials and topics under investigation include fiber-reinforced composites, the aging of polymer wiring insulation in aerospace applications, interface/electrolyte characterization of solid oxide fuel cells and materials, the characterization of thin film electroceramics for grain vs. grain boundary effects, and the measurement of powder conductivities via the novel “power-solution-composite” method. The potential also exists for the characterization of soft materials, including biological and biomaterials.
