Piezoelectricity of Cholesteric Elastomers

, 1994
We consider theoretically the properties of piezoelectricity in cholesteric elastomers. We deduce using symmetry considerations the piezoelectric contributions to the free energy in the context of a coarse-grained description of the material. In contrast

Interface crack between dissimilar one-dimensional hexagonal quasicrystals with piezoelectric effect [PDF]

, 2019
In this paper, an interface crack between dissimilar one-dimensional (1D) hexagonal quasicrystals with piezoelectric effect under anti-plane shear and in-plane electric loadings is studied. By using integral transform techniques, the mixed boundary value

Effects of electrostatic force on piezoelectric materials under high electric field: Impact on GaN-based nanoscale structures

, 2011
The determination of the electromechanical properties of materials for a parallel-plate capacitor structure is affected by the electrostatic force between their electrodes. The corrections induced by this electric-field-induced stress are usually assumed

Modeling an elastic beam with piezoelectric patches by including magnetic effects

, 2014
Models for piezoelectric beams using Euler-Bernoulli small displacement theory predict the dynamics of slender beams at the low frequency accurately but are insufficient for beams vibrating at high frequencies or beams with low length-to-width aspect ...

Origin of the anomalous piezoelectric response in wurtzite Sc$_x$Al$_{1-x}$N alloys

, 2010
The origin of the anomalous, 400% increase of the piezoelectric coefficient in Sc$_x$Al$_{1-x}$N alloys is revealed. Quantum mechanical calculations show that the effect is intrinsic.
