Beyond‐Classical Ferroelectric Metamaterials: 3D‐Printed Planar Lattices With Programmable Electro–Thermo–Mechanical Coupling
ABSTRACT Conventional porous ferroelectric materials often improve voltage‐related figures of merit at the expense of piezoelectric charge coefficients. Here, we establish a topology–polarization co‐design strategy for planar lattice‐based ferroelectric metamaterials, which integrate underlying geometry, deformation mo...
