Pyroelectric Nanogenerator: Harvesting Energy from ΔT/Δt

A pyroelectric nanogenerator turns a changing temperature — not a steady one, and not mechanical strain — directly into electrical charge. This simulator renders a ferroelectric nanofilm sandwiched between two electrodes, cycles it through heating and cooling at a rate you control, and animates its internal dipole field collapsing and rebuilding with the Curie-Weiss law while real charge markers flow through an external load in the correct direction and at the correct rate, governed by I = A·p·(dT/dt). Switch between PVDF, PZT and ZnO nanowires to see how pyroelectric coefficient and Curie temperature change the output, and push the swing past T_c to watch the film disorder into its paraelectric phase.
