Impedance analysis of oil conductivity and pixel non-uniformity in electrowetting displays
Results in Physics, 2020 The electrical conductivity of the oil film is a key property of electrowetting displays (EWD) and its evolution probably correlates to the device lifetime. In this report, we fabricate an EWD device and measure its electrical impedance spectrum.

ELECTRIC IMPEDANCE OF ASTERIAS EGGS [PDF]
Journal of General Physiology, 1936 The alternating current resistance and capacity of suspensions of unfertilized eggs of Asterias forbesi have been measured at frequencies from one thousand to sixteen million cycles per second. The plasma membrane of the egg has a static capacity of 1.10µf/cm.2 which is practically independent of frequency.

Effects of lead exposure on blood electrical impedance spectroscopy of mice
BioMedical Engineering OnLine, 2021 Background Lead is a nonessential heavy metal, which can inhibit heme synthesis and has significant cytotoxic effects. Nevertheless, its effect on the electrical properties of red blood cells (RBCs) remains unclear.

Electrical impedance spectroscopy (EIS) for biological analysis and food characterization: a review [PDF]
Journal of Sensors and Sensor Systems, 2017 Electrical impedance spectroscopy (EIS), in which a sinusoidal test voltage or current is applied to the sample under test to measure its impedance over a suitable frequency range, is a powerful technique to investigate the electrical properties of a ...

Electrical Impedance Tomography
British Journal of Radiology, 1997 Electrical impedance tomography (EIT) is a technique which allows cross-sectional images related to the local electrical impedance within an object to be reconstructed from sets of measurements made on its surface. The main drive behind the development of EIT has been its possible application in medical imaging, as biological tissues are known to ...

Ex vivo electrical bioimpedance measurements and Cole modelling on the porcine colon and rectum
Scientific ReportsDifferent pathological changes in the large intestine wall, associated with the development of different chronic diseases, including colorectal cancer, could be reflected in electrical bioimpedance readings. Thickness and composition of the mucus bilayer

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Electrical impedance of acupuncture meridians: the relevance of subcutaneous collagenous bands. [PDF]
PLoS ONE, 2010 The scientific basis for acupuncture meridians is unknown. Past studies have suggested that acupuncture meridians are physiologically characterized by low electrical impedance and anatomically associated with connective tissue planes.
