Dielectric charging in MEMS with dielectric-dielectric contacts

2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII), 2013
This paper analyzes the dielectric charging effects in microelectromechanical capacitive switches with dielectric-dielectric contacts. Measurements were performed on switches with different contact topologies to characterize the charging of the surface and the bulk of the dielectric under different hold-down voltages and periods.

Optimization of the dielectric layer for electrowetting on dielectric

Integration, 2019
Abstract In this work the minimum actuation voltage Vmin for droplet actuation with electrowetting on dielectric (EWOD) is analyzed. At first, the theoretical background of drop transport with EWOD is shown. Then the impact of thin dielectric films deposited with atomic layer deposition (ALD) and super-hydrophobic layers on the minimum required ...

Theory of Dielectric Breakdown in Metal-Loaded Dielectrics

Physical Review B, 1987
We have examined a very simple model of dielectric breakdown in random mixtures of metal and dielectric.1,2,3 We expect this analysis to be relevant for an class of materials which are composed of a random mixture of metallic particles embedded in a dielectric matrix.
