Ferroelectric materials possess a spontaneous electric polarization that can be reversed by an external electric field. This switchable polarization underlies a vast family of technologies — from ultrasound transducers and inkjet printheads to non-volatile memory and precision actuators. The piezoelectric effect, where mechanical stress produces voltage and vice versa, is the workhorse mechanism connecting these materials to the engineering world.
These simulations let you trace the classic P-E hysteresis loop, compute piezoelectric coefficients and electromechanical coupling, observe the ferroelectric-to-paraelectric phase transition at the Curie temperature, watch 180-degree and 90-degree domain walls sweep through a crystal, and design a vibration energy harvester that converts ambient motion into usable electrical power.
