Evaluate Interdigitated Electrode Sensors with the MFIA

on 16.06.2021 at 15:45 by Meng on Blog of Meng Li
In the previous blog posts, we demonstrated conductivity and permittivity measurements of liquids using an MFIA impedance analyzer. To reach the best accuracy, the measurements were carried out using immersion probes or dielectric fixtures with a precisely defined electrode area […]

Take Your Dielectric Measurements to the Liquid State

on 25.05.2021 at 14:06 by Meng on Blog of Meng Li
Liquid dielectrics are dielectric materials in a liquid state and are widely used in electrical insulation as well as cooling. Nonetheless, their fluidity also makes accurate dielectric measurements a challenge. In a previous blog post, we saw how to measure […]

Measuring Dielectric Properties of Materials with Varying Thickness

on 30.09.2020 at 08:52 by Meng on Blog of Meng Li
Introduction A dielectric is traditionally defined as an electrical insulator, with very poor conductivity at DC [1]. However, because of its polarizability, charges can be stored in a dielectric material, typically in the format of dipoles, in the low and […]
