Interface Design for CMOS-Integrated Electrochemical Impedance Spectroscopy (EIS) Biosensors

Electrochemical Impedance Spectroscopy (EIS) is a powerful electrochemical technique to detect biomolecules. EIS has the potential of carrying out label-free and real-time detection, and in addition, can be easily implemented using electronic integrated circuits (ICs) that are built through standard semiconductor fabrication processes. This paper focuses on the various design and optimization a...

Equivalent Electrical Circuit Modeling of Ceramic-Based Microbial Fuel Cells Using the Electrochemical Impedance Spectroscopy (EIS) Analysis

The effect of the thickness of ceramic membrane on the productivity of microbial fuel cells (MFCs) was investigated with respect to the electricity generation and domestic wastewater treatment efficiencies. The thickest ceramic membrane (9 mm) gained the highest coulombic efficiency (27.58±4.2 %), voltage (681.15±33.1 mV), and current and power densities (447.11±21.37 mA/m2, 63.82±10.42 mW/m2) ...

Evaluation of Organic Coatings with Electrochemical Impedance Spectroscopy

This seemingly basic equation actually hides some sophisticated assumptions and concepts. First, it applies only to the time varying, alternating, or ac, components of the current and voltage. Secondly, it is not sufficient to just tell how big the voltage and current signals are, we must also say how they are related in time, since they are both timevarying, ac quantities. Finally, the sizeand...

Stress Corrosion Cracking Detection of Sensitized Stainless Steel 304 in Chloride Media by Using Electrochemical Impedance Spectroscopy (EIS)

Electrochemical impedance spectroscopy (EIS) was used to detect stress corrosion cracking (SCC) in stainless steel 304 alloy exposed to an aqueous environment at 120 °C. Stainless steel 304 alloy as u-bend was tested in the solution that contains 40 weight percent of magnesium chloride. U-bended samples were prepared according to ASTM G30. EIS measurements were always performed simultaneously o...
