Abstract A higher-grade theory of non-ferromagnetic thermo-elastic dielectrics which incorporates the local mass displacement, heat flux gradient, polarization inertia, and flexodynamic effects is developed. The process displacement associated with changes in material microstructure. Using fundamental principles continuum mechanics, electrodynamics, non-equilibrium thermodynamics, gradient-type...

This paper develops the equilibrium equations describing flexoelectric effect in soft dielectrics under large deformations. Previous works have developed related theories using a coupling tensor of mixed material-spatial character. Here, we formulate model terms completely defined material frame, with same symmetries small-strain flexocoupling and leading naturally to objective polarization fie...

Recent discovery of the ferroelectric nematic phase N_F resurrects a question about stability uniform state with respect to formation either standard for solid ferroelectrics domain structure, or often occurring in liquid crystals space modulation polarization vector P (and naturally coupled director. In this work within Landau mean-field theory we investigate linear minimal model admitting con...

Night-Photomonitoring In article number 2210621, Hyungtak Seo, and Mohit Kumar, report long-range impact of the localized inhomogeneous strain-induced flexoelectric potential, which is then used to develop mechanically regulated, self-powered (0 V), ultrafast, broadband (λ = 365–1720 nm), highly responsive pyro-photosensors. A proof-of-concept ultrafast night movement monitors (>720 km h−1), hi...
