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.

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 ...

Piezoelectric Effect Tuning on ZnO Microwire Whispering-Gallery Mode Lasing.

ACS Nano, 2018
We report a dynamic tuning on coherent light emission wavelengths of single ZnO microwire by using the piezoelectric effect. Owing to the dominant role occupied by the piezoelectric polarization effect in the wurtzite-structure ZnO microwire, the ...

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 ...

Surface piezoelectricity: Size effects in nanostructures and the emergence of piezoelectricity in non-piezoelectric materials

Journal of Applied Physics, 2011
In this work, using a combination of a theoretical framework and atomistic calculations, we highlight the concept of “surface piezoelectricity,” which can be used to interpret the piezoelectricity of nanostructures. Focusing on three specific material systems (ZnO, SrTiO3, and BaTiO3), we discuss the renormalization of apparent piezoelectric behavior ...

Piezoelectric Effects in Rocks

1971
Theoretical consideration of the symmetry of piezoelectric aggregates of quartz, of quartz-bearing rocks and of rocks which contain nepheline and tourmaline have permitted us to hypothesize the existence of a piezoelectric effect in such rocks. However, this does not assure that they do exist.
