Electrical impedance in biological systems exploits the frequency-dependent opposition that tissues or cells present to the flow of an alternating current. By measuring impedance across a range of ...

When developing new drugs, understanding their effects on ion channels in the body, such as the human ether-a-go-go-related gene (hERG) ion channel found in neurons and heart muscle cells, is critical ...

Electrochemical impedance spectroscopy (EIS) is an analysis method used the surfaces of various systems, batteries, photovoltaic systems, and some life science applications. It is based on introducing ...

Known as EIS, Electrochemical impedance spectroscopy is an increasingly common non-destructive technique that is used to analyze and identify a material’s physicochemical properties, especially at the ...

ECISTM (Electric Cell-Substrate Impedance Sensing) is the only commercially available technology which continuously monitors TEER under dynamic flow conditions. In their natural environment, ...

Proper impedance paths are critical to shock prevention. The National Safety Council estimates that nearly 300 people die in the United States each year from electric shocks on 120V or 277V circuits.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have demonstrated that electrochemical impedance spectroscopy (EIS) can be a powerful non-destructive tool to study the degradation ...

Inadequate shielding and bad grounding are often blamed when measurements are inaccurate, especially in high-impedance applications. In fact, shielding and grounding problems are frequently ...

Recently, researchers developed a non-invasive method combining electrical impedance tomography and extracellular voltage activation to evaluate drug effects on ion channels. The resulting printed ...
