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.
transducers generate waves in response to varying voltages via the aforementioned piezoelectric effect.

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.

Ceramics for a Venus Ultrasonic Rock Sampling Tool.
Smart materials studied in the report include piezoelectric, magnetostrictive, electrochromic, thermoresponsive, and electrostrictive
The organic composite is a mixture of electrostrictive
polyvinylidene-fluoride-trifluoroethylene, an electroactive polymer, as the matrix, and copper-phthalocyanine, an organic semi-conductor with a high dielectic constant, as the filler.
The types of smart materials include shape memory alloys, shape memory polymers, electrostrictive
, magnetostrictive and piezoelectric materials.
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.
Piezoelectric materials, which develop electric polarization when subjected to strain, and electrostrictive
materials, which experience an elastic strain when subjected to an electric field, loose stroke at low temperature.
