Dielectric Gels with Microphase Separation for Wide‐Range and Self‐Damping Pressure Sensing

Advances in Materials, 2023
Omnipresent vibrations pose a significant challenge to flexible pressure sensors by inducing unstable output signals and curtailing their operational lifespan.

Investigation of Dielectric Hysteresis in Ferroelectric Liquid Crystals

Molecular Crystals and Liquid Crystals Incorporating Nonlinear Optics, 1987
Abstract The device for measurement of spontaneous polarization, resistance and capacity of ferroelectric liquid crystals in a wide amplitude and frequency range of applied electric field is described. Data for spontaneous polarization and different type hysteresis loops for smectic C* liquid crystals are presented.

Ultrathin Van der Waals Lanthanum Oxychloride Dielectric for 2D Field‐Effect Transistors

Advances in Materials, 2023
Downsizing silicon‐based transistors can result in lower power consumption, faster speeds, and greater computational capacity, although it is accompanied by the appearance of short‐channel effects.

Dielectric Hysteresis Loops of Photosensitive Relaxor Ferroelectrics

Ferroelectrics, 2005
We have studied the effects of illumination by a photoactive light on the polarization switching of strontium-barium niobate crystals in quasi-static periodic electric field. The illumination results in an increase of the polarization amplitude and of the most probable coercive field.

Biologically Emulated Flexible Sensors With High Sensitivity and Low Hysteresis: Toward Electronic Skin to a Sense of Touch.

Small, 2022
Recently, flexible pressure sensors (FPSs) have attracted intensive attention owing to their ability to mimic and function as electronic skin. Some sensors are exploited with a biological structure dielectric layer for high sensitivity and detection ...

Observation of Bistability and Hysteresis in Optical Binding of Two Dielectric Spheres

Physical Review Letters, 2006
Using a dual-beam fiber optic trap, we have experimentally observed bistability and hysteresis in the equilibrium separations of a pair of optically bound dielectric spheres in one dimension. These observations are in agreement with our coupled system model in which the dielectric spheres modify the field propagation, and the field self-consistently ...

Hysteresis of dielectric properties of Li-Ti-Ferrite ceramics

Russian Physics Journal, 2004
Field dependences of Li-Ti ferrite ceramics polarization are obtained. When related to temperature, these dependences exhibit either non-linear behavior or non-linearity and hysteresis. Electric Barkhausen’s pulses are revealed. Temperature dependences of the electric pulse heights are obtained after re-polarization of the specimens in the electric ...

Hysteresis in Dielectric Properties of Fluid-Saturated Porous Media

Proceedings of SPE Asia Pacific Improved Oil Recovery Conference, 1999
Abstract We present in this paper the results of measurements of the complex dielectric permittivity and electric conductivity in three different porous media, made from unconsolidated acid-purified quartz sand and glass grains. To ensure the generality of the results, we use sand and glass grains of different geometry and particle size ...

Hysteresis loss and dielectric constant in barium titanate

British Journal of Applied Physics, 1967
A qualitative description is presented for the behaviour of the hysteresis loss and the dielectric constant in ceramic barium titanate in terms of the properties of single-crystal barium titanate. When the effects of imperfections and interaction between crystallites are introduced, this description explains the similarity between the dielectric ...
