The D-bar method for electrical impedance tomography—demystified

Inverse Problems, 2020
Electrical impedance tomography (EIT) is an imaging modality where a patient or object is probed using harmless electric currents. The currents are fed through electrodes placed on the surface of the target, and the data consists of voltages measured at ...

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.
