ENHANCING THE DIELECTRIC PERMITTIVITY OF ELASTOMERS

, 2008
The electromechanical transduction properties of any dielectric elastomer are intrinsically regulated by the dielectric permittivity of the material. This parameter proportionally controls both the achievable active stresses and strains. Accordingly, a suitable increase of the material permittivity may provide a valuable means to improve the ...

Quantifying dielectric permittivities in the nonlinear regime

Journal of Physics: Condensed Matter, 2021
Abstract In contrast to the static dielectric permittivity, ε , associated with linear response, its high-field counterpart, ε E , is not a material specific quantity, but

Hemispherical dielectric permittivity cell

Review of Scientific Instruments, 1978
A three-terminal dielectric cell based on a hemispherical design is constructed for low-temperature measurements of dielectric permittivity. The cell has a small sample volume, is geometrically stable, and shows no frequency dependence of capacitance. Measurements on test samples are presented showing both cell constant stability data and the linearity

Dipolar Correlations and the Dielectric Permittivity of Water

Physical Review Letters, 2007
The static dielectric properties of liquid and solid water are investigated within linear response theory in the context of ab initio molecular dynamics. Using maximally localized Wannier functions to treat the macroscopic polarization we formulate a first-principles, parameter-free, generalization of Kirkwood's phenomenological theory.

Dielectric Permittivity of BiTeI

Inorganic Materials, 2004
The dielectric permittivity and volume electron energy loss spectra of the ferroelectric semiconductor BiTeI are calculated for the E ⊥ c polarization in the range 0–12 eV. The spectra are decomposed into elementary components (13), and their principal parameters are evaluated.

Measurement of the permittivity of dielectrics

Measurement Techniques, 1968
1. Our experimental investigations have shown that the accuracy in measuring the polarization parameters and determining the e value depends mainly on the error in calibrating the polarizing and the analyzing devices, which, in our case, did not exceed 5–7%. 2.
