Michael A Miller, Stephen J Hudak Jr: Electromechanical and electrochemical impedance spectroscopy for measuring and imaging fatigue damage. Southwest Research Institute, Baker Botts L, November 28, 2000: US06151969 (13 worldwide citation)

EIS and EMIS methods of assessing the fatigue status of a material. The EIS method uses an electrochemical transducer cell to apply electrical perturbations to the material, and to acquire voltage and current measurements over a range of frequencies. The impedance at each frequency is calculated, re ...
