Their potential to be used as high permittivity dielectrics [1-6], organic ferroelectric memory devices [7, 8], electrostrictive
actuators [9-12], and high energy density capacitors [13-20] has been widely studied over the last few decades.
Brillouin-Mandelstam scattering, originally discovered in the early 1920s, is the coupling of light waves and sound waves through electrostrictive
optical forces and acousto-optic scattering.
Topics include: dielectricity, piezoelectricity, pyroelectricity, and ferroelectricity; a structural approach to thermodynamic study; ferroelectric-paraelectric phase transition thermodynamic modeling; formalism; electric characterization, piezoelectric resonators and filters; high overtone bulk acoustic resonators; electrostrictive
resonators, and thin film piezoelectric transducers.
On the other hand, electrostrictive
materials have a very fast response rate, but require a high voltage.

Theorists at NIST have performed first principles calculations that have demonstrated that Pb-O vacancy pairs can be a significant source of "random" electric fields in Pb-based perovskite compounds, materials under development for electrostrictive
transducers, actuators, and sonar devices for medical imaging and military applications.
The load force is represented by the force that acts on the surface of film in the time of electrostrictive
Electromechanical parameters, strain, apparent electrostrictive
coefficient and response time, were determined from the thickness deformation of polymer films induced by d.
Electroactive polymers, which respond to electrical stimulation, include electrostrictive
polymers, electronic electroactive polymers, and ionic electroactive polymers.

In contrast to this giant electrostrictive
response and Pr values, high pyroelectric constant was found on the first stretched then poled (FSP) PVDF-HFP (15%) copolymer films with the maximum value of 49 [micro]C/([m.
