Electric Auxetic Effect in Piezoelectrics

Physical Review Letters, 2020
Auxetic materials are characterized by a negative Poisson's ratio that they expand laterally in the directions perpendicular to the applied stretching stress and vice versa. Piezoelectrics will change their dimensions when exposed to an external electric field.

Influence of Multiple Piezoelectric Effects on Piezoelectric Coefficient of Piezoelectric Ceramics

Applied Mechanics and Materials, 2011
In this paper, theoretical analysis is performed on the influence of multiple piezoelectric effects on piezoelectric coefficients. And a kind of classical piezoelectric ceramics was adopted to conduct the experimental validation. The experimental results of short-circuit boundary condition are obtained by the methods that a capacitor whose capacitance ...

Piezoelectric effect in renal calculi

IEEE Transactions on Biomedical Engineering, 1991
The piezoelectric effect is investigated for the first time in renal calculi in vitro. The kidney stones are shaped from solid samples as well as from stones crushed into powder and pressed into tablets. Presence of alpha quartz in the renal calculi is investigated by an X-ray technique and the presence of this constituent also helps to explain the ...

Origin of the piezoelectric effect in bone

Calcified Tissue Research, 1971
The piezoelectric effect was measured in samples of human bone and repeated with the same samples after either demineralization or decollagenation. The results indicate that at least part and possibly all of the piezoelectric effect found in whole bone arises from the organic component. The existence of two alternatives results from the unknown role of

THE DISCOVERY OF THE PIEZOELECTRIC EFFECT

Archive for History of Exact Sciences, 2003
L'effet piezo-electrique a ete mis en evidence en 1880 par les freres Pierre et Jacques Curie. La decouverte de ce phenomene a pour origine un travail experimental et s'appuie a la base sur une theorie elaboree en reliant ce phenomene a la geometrie atomique des cristaux et en enoncant ses principales lois.

Piezoelectric drill based on converse piezoelectric effect

2008 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications, 2008
A new type of mode convert piezoelectric drill is presented. The drill uses converse piezoelectric effect to work. When exciting voltage is applied on piezoelectric ceramics, the basic structure of the drill will produce longitudinal vibration, which will be converted to local bending vibration by the drill bit fixed on the basic structure with an ...

Dual piezoelectric beam robot: The effect of piezoelectric patches’ positions

Journal of Intelligent Material Systems and Structures, 2015
Inspired from linear traveling wave ultrasonic motors, a dual piezoelectric beam robot is presented. It consists of an aluminum beam structure, with two non-collocated piezoelectric patches bonded on its surface. The aim of this article is to study the effect of the piezoelectric patches’ positions on the performance of the robot.
