The piezoelectric effect in polymers

Polymer Mechanics, 1972
A series of polymers with varying polarity and chain rigidity has been investigated. On the basis of the results obtained it is concluded that piezoelectric properties are to be found in polarized polymers with small dipole groups and a rigid chain due to their polarity.

Effective charges and piezoelectricity

Physical Review B, 1974
The effective charge for piezoelectricity is calculated using the bond-orbital model and Martin's internal-displacement parameters. Direct and simple calculations made with no additional parameters lead to a semiquantitative description of this effect.

Piezoelectric effects in electroreflectance

Solid State Communications, 1970
Abstract The contribution of piezoelectric strain to electroreflectance is investigated. The symmetry properties of this contribution are deduced for zincblende materials, and contrasted with those of electroreflectance. Separate observations of these contributions is shown to be possible, and good agreement with the phenomenological, tensorial ...

Piezoelectricity Effect Detector

Kristall und Technik, 1974
AbstractAn apparatus for the detection of the piezoelectricity effect in non‐conducting crystals is described. It is possible to mark the crystal resonance frequency and show the resonance curve on the oscilloscope, both with or without mechanical contact between the crystal and electrodes.

Piezoelectric Effects in Collagen

Japanese Journal of Applied Physics, 1964
The direct and converse piezoelectric effects have been observed in the Achilles tendon of ox and horse, which consists of collagen fibers in which the collagen molecules are highly orientated and crystallized. The matrix of piezoelectric constant is concordant with that derived for and unidirectionally oriented system of crystallites of collagen with ...

On the Piezoelectric Effect of Bone

Journal of the Physical Society of Japan, 1957
The piezoelectric effect of bone has been observed similarly to the case of wood or ramie. The specimens were cut out from the femur of man and ox, and dried completely by heating. The piezoelectric constants were measured by three different experiments, that is, measurements of the static direct effect, the dynamic direct effect and the dynamic ...

Comparative analysis on piezoelectric effect and electromagnetic effect for the further study of multi-piezoelectric effect

Proceedings of 2012 International Conference on Measurement, Information and Control, 2012
This paper is devoted to the study on similarity of piezoelectric effect and electromagnetic effect from the following points, which are the model of piezoelectric effect and electromagnetic effect, the fundamental equations of piezoelectric field and electromagnetic field, the multi-induced effect of piezoelectric effect and electromagnetic effect ...

Chiral effects in piezoelectricity

Mechanics Research Communications, 2017
Abstract This paper is concerned with the linear theory of piezoelectricity for Cosserat continua. The deformation of homogeneous and isotropic chiral materials is investigated. First, a counterpart of the Boussinesq–Somigliana–Galerkin solution in the classical elastostatics is presented.
