The electrical response of PZT95/5 ferroelectric ceramics subjected to normal mode shock stress was investigated. Based on the improved experimental devices and solving the matching problem of experimental specimens and loads, the maximum output current on a 60μH inductive load is 1660A, and the maximum peak voltage on resistive load is over 100kV.
Using self-consistent mean field theory and series perturbative expansion, we investigated the nonlinear response of a nonlinear ER fluid consisting of nonlinear spherical particles and linear substrate. Under a sinusoidal (ac) field, the electrical response of a nonlinear ER fluid contains generally the contributions of higher-order harmonics. We give the dipole moment of nonlinear spherical particles its harmonic response.
An equivalent electrical circuit corresponding to the total electrical response of all individual components is proposed for the composite studied.
It is established that the electrical response of a DNA molecule to an applied electric field depends on the boundary conditions and the potential profile along the molecule.
Electrical response of a polydomain ferroelectric to cyclic temperature variations
It is shown experimentally that the electrical response to temperature changes by a polydomain ferroelectric, as recorded in measurements of the electric dipole and quadrupole moments, is quite different during heating and during cooling.
The temperature dependences of the real and imaginary parts of the complex permittivity of diserine sulfate monohydrate crystals and of their electrical response in different crystallographic directions to a change in temperature are investigated.
An improved theoretical mode of electrical response of normal mode shock wave compressed ferroelectric ceramics is introduced in this paper. We not only consider the relaxation for the dielectric and conductivity of the ferroelectric material but also take account of the shock front traveling in the specimen. Calculations show that the mode is accord with experiments.

Using self-consistent mean field theory and series perturbative expansion, we investigated the nonlinear response of a nonlinear ER fluid consisting of nonlinear spherical particles and linear substrate. Under a sinusoidal (ac) field, the electrical response of a nonlinear ER fluid contains generally the contributions of higher-order harmonics. We give the dipole moment of nonlinear spherical particles its harmonic response. Further, we obtain the analytic expressions of the higher harmonics of dipole moment and the averaged local field. Our numerical results show that it is important to take the multiple image interaction into account in the case of small distance between particles and large dielectric contrast.
