electrostrictive

electrostrictive

Materials that change in size in response to an electric field and produce electricity when stretched are called electrostrictive. These materials are primarily used as precision control systems such as vibration control and acoustic regulation systems in engineering, vibration damping in floor systems, and dynamic loading in building construction.

According to the results of the experiment, under conditions of low hydrostatic pressure, bubbles can exist both near the electrodes and be formed with time after applying voltage to them due to microcavitation, local overheating of liquid and electrostrictive phenomena.
The autoadaptive materials, such as magneto-and electrostrictive solids and magneto- and electrorheological fluids, are the materials that can sense external disturbances and modify their characteristics intentionally to mitigate the effects of the external influence.
With the development of modern precision instruments, piezoelectric, electrostrictive, magnetostrictive, shape-memory alloy, and electrorheological fluid actuators are most commonly used.
By selecting a pump wavelength away from resonance with any absorption features of the gas mixture, electrostrictive gratings can be used to perform LIGS measurements.
Smart material includes ferroelectric materials (piezoelectric, electrostrictive, and magnetostrictive), variable rheology materials (electrorheological, magnetorheological), and shape memory alloys.
The induced electrostrictive volumetric body force [??] can be written as follows [20]:
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.

[1] observed a magnetic-field-induced strain of 0.2% in 1996, large field-induced strain of 9.5% has been achieved in Ni-Mn-Ga single crystal [2], which is much greater than those of magnetostrictive, piezoelectric, or electrostrictive. In addition, the material has a wide bandwidth of strain response, reported to be within kHz range [3].
