Local electrochemical impedance spectroscopy in dynamic mode of galvanic coupling
Electrochimica Acta, 2018Abstract A novel method that combines local electrochemical impedance spectroscopy and mapping in dynamic mode is proposed. Method was validated over two galvanic couplings, namely zinc/copper and cadmium/copper. Impedance spectrum response for all measuring points was obtained by means of simultaneous implementation of selected range of frequencies.

Dynamic Electrochemical Impedance Spectroscopy
ECS Transactions, 2009The hardware and software for a dynamic electrochemical impedance spectroscopy system are described. The applied waveform is a continuous computer-generated multisine waveform added to a potential sweep. A fast potentiostat applies the potential signal and the impedance is derived from the Fourier transforms of the measured current and potential ...
