Influence of the PCB Manufacturing Process on the Measurement Error of Planar Relative Permittivity Sensors Up To 100 GHz

IEEE Transactions on Microwave Theory and Techniques, 2019
Accurate and precise knowledge of the relative permittivity of printed circuit board (PCB) materials is essential for the reliable design of high-frequency circuits. For simplicity reasons, planar, resonant permittivity sensors, which are directly integrated on the unknown PCB material, are widely used.

In-situ aging monitoring of transformer oil via the relative permittivity and DC conductivity using novel interdigitated dielectrometry sensors (IDS)

Sensors and Actuators B: Chemical, 2019
Abstract Oil filled electrical transformers are present worldwide. Their lifetime is depended on many factors such as load, age and their environment, making the theoretical health prediction a challenge. A smarter approach is to monitor the health of these transformers online using in-situ sensors.
