Ferroelectric materials are a class of multifunctional or so-called “smart” materials that have gained increasing scientific and technological interest over recent decades. Beyond their established applications as actuators and sensors in high-precision positioning systems (e.g., semiconductor manufacturing and microelectronics), ferroelectrics are also being explored for advanced functionalities, such as energy harvesting and ultrasonic transducing. The technical achievements of recent years are also increasingly pushing their use in cryogenic environments, notably in the field of quantum computing. A core challenge in modeling ferroelectrics lies in their inherently nonlinear and hysteretic behavior, stemming from irreversible domain switching processes. These phenomena are accompanied by dissipation, self-heating, and other loss mechanisms, which must be accurately captured in predictive models. Approaches range from phenomenological constitutive models to micromechanical, atomistic, and phase-field descriptions, each offering insight at different length and time scales. The verification of the validity of any modeling approach is highly dependent on the possibility of experimental comparisons. Since domain switching occurs at the sub-grain level within representative volume elements (RVEs), resolving these effects necessitates scale-bridging techniques. The resulting multi-scale character of the problem demands a comprehensive methodological framework to adequately describe the thermo-electro-mechanically coupled response of such materials. This minisymposium invites contributions addressing recent advances in the modeling, simulation, and experimental characterization of ferroelectric materials. Topics of interest include, but are not limited to: • Thermo-electro-mechanically coupled modeling including phenomenological, mi-cromechanical, phase-field or atomistic approaches • Multi-scale methods and homogenization techniques • Experimental characterization methods • Ferroelectricity, ferroelasticity, piezoelectricity, electrostriction, electro-/elastocaloric effects, pyroelectricity and flexoelectricity • Domain kinetics and switching phenomena • Rate-dependent phenomena: viscoelasticity, creep • Fatigue behavior and degradation mechanisms • Quasi-static, dynamic, and resonant regimes • Lead-based and Lead-free ferroelectric materials • Applications in sensing, actuation, energy harvesting, transduction and cryogenic environments
