This minisymposium is dedicated to the flexoelectric effect in electroactive materials, including rigid dielectrics, ferroelectrics, semiconductors, soft polymers, thin films, heterostructures, biological membranes, liquid crystals, and 2D materials, among others. The goal of the minisymposium is to cover a wide spectrum of recent research developments in computational, theoretical, and experimental approaches associated with flexoelectric materials, including (but not limited to): Continuum modeling (large deformations, constitutive models, micromorphic approaches, surface effects, boundary conditions) Computational modeling (mixed finite elements, immersed boundary method, isogeometric analysis, meshless discretizations, stabilization techniques, computational quantum mechanics) Nonlinear rod or shell modeling Couplings to other physics (piezoelectricity, thermal effects, magnetics, flexo-phototronics, fracture, friction, damage) Material and structural instabilities (buckling, wrinkling, rippling) Multi-scale modeling (FE2, homogenization, metamaterials) Characterization (experimental methods, ab-initio methods, quantum mechanics) Design and optimization (shape optimization, topology optimization) Manufacturing techniques (3D printing, lithography, thermal curing, coating) Applications (soft robotics, sensing, actuation, energy harvesting, catalysis, diodes, transistors)
