Pyroelectric Nanogenerator: Harvesting Energy from ΔT/Δt (2D)

This is the 2D counterpart to the 3D pyroelectric nanogenerator scene, computing the identical charge-current physics through analytic panels instead of a rendered slab: a dipole cross-section that collapses and rebuilds under the Curie-Weiss law as heating and cooling markers flow through an external load, a scrolling temperature & dT/dt strip chart, and a pyroelectric current output chart. 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.
