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), 2013This 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.

Observation of a single-beam gradient force optical trap for dielectric particles.
Optics Letters, 1986Optical trapping of dielectric particles by a single-beam gradient force trap was demonstrated for the first reported time. This confirms the concept of negative light pressure due to the gradient force.

Dielectric relaxation and dielectric fluctuations [PDF]
Journal of Physics C: Solid State Physics, 1978 The relation between the frequency dependent dielectric constant and the fluctuations in the dielectric polarisation is re-examined from the standpoint of Felderhof's macroscopic theory of electric and magnetic fluctuations. Contributions of the electronic degrees of freedom to the polarisation are included in the formalism; they are treated as an ...

Dielectric relaxation in solids
, 1983This review presents a wide-ranging broad-brush picture of dielectric relaxation in solids, making use of the existence of a `universality' of dielectric response regardless of a wide diversity of materials and structures, with dipolar as well as charge ...

Starting from the screening in conductors, an algorithm for the accurate calculation of dielectric screening effects in solvents is presented, which leads to rather simple explicit expressions for the screening energy and its analytic gradient with ...

Optimization of the dielectric layer for electrowetting on dielectric
Integration, 2019Abstract 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 ...
