Acoustic transducers are essential for object localization and environmental sensing. Conventional transducers rely on piezoelectric crystals, whose acoustic-electric response is fixed by the crystal lattice's inherent asymmetry and orientation. This results in static coupling behavior, necessitating bulky arrays of rigid elements with complex wiring and high computational demands for directional sensing. Here, we report a fundamentally new class of acoustic-electric coupling that emerges from topology-governed charge transport in 3D micro-architected piezoelectric metamaterials. Unlike...

While piezoelectricity in bulk crystals is strictly confined by lattice symmetry, architected metamaterials overcome these limits, unlocking previously forbidden electromechanical couplings via mesoscale geometry. However, a comprehensive framework relating metamaterial topology to the full piezoelectric tensor remains absent, particularly in the dynamic regime where structural resonances render responses highly frequency dependent. Furthermore, current AI-driven design methods focus on static properties or natural crystals, leaving dynamic tensor discovery largely out of reach.
