Multiscale electro-mechanical behaviours of TPMS piezoelectric metamaterials

Conventional bulk piezoelectric materials face intrinsic performance bottlenecks in simultaneously achieving high electromechanical sensitivity and low acoustic impedance. TPMS metamaterials, owing to their unique bi-continuous structure and superior mechanical properties, stand out as ideal candidates. However, existing research lacks a systematic investigation into their configurational mechanisms and cross-scale electro-mechanical behaviors. This study investigates the multiscale electromechanical behavior of TPMS structures as piezoelectric functional layers. At the microscale, the influences of TPMS configurations, material composition, and volume fractions on homogenized electromechanical coefficients…
