Functionalized BaTiO3 enhances piezoelectric effect towards cell response of bone scaffold.

Colloids and Surfaces B: Biointerfaces, 2019
Piezoelectric effect of polyvinylidene fluoride (PVDF) plays a crucial role in restoring the endogenous electrical microenvironment of bone tissue, whereas more β phase in PVDF leads to higher piezoelectric performance.

Conjuncted Pyro‐Piezoelectric Effect for Self‐Powered Simultaneous Temperature and Pressure Sensing

Advances in Materials, 2019
Ferroelectric materials use both the pyroelectric effect and piezoelectric effect for energy conversion. A ferroelectric BaTiO3‐based pyro‐piezoelectric sensor system is demonstrated to detect temperature and pressure simultaneously.

Radiation piezoelectric effect

Physics Letters A, 1976
Abstract The results of experimental investigation of a new phenomenon - appearance of an emf across a single germanium sample subject both to irradiation with charged particles and to uniaxial deformation in a direction perpendicular to the particle beam (radiation piezoelectric effect - RPE) - are reported.

Piezoelectric effect-based detector for spectroscopic application

Optics and lasers in engineering, 2019
A standoff laser spectroscopy sensor based on a broadband tunable external cavity quantum cascade laser (ECQCL) and a piezoelectric effect-based detector was developed for simultaneous detection of multiple chemicals. Instead of using a standard infrared

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 ...

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.

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.
