Colossal Photovoltaic Current in Ferroelectric Oxide by Constructing Defect Band
Colossal photovoltaic current density of 34.36 mA/cm2 under 375 nm illumination has been achieved in the Pb‐deficient PbTiO3 film. The ultraviolet photoresponsivity surpasses that of all reported ferroelectric materials. This enhancement is attributed to the junction effect between the Pb‐deficient and non‐defective layers.

Programmable Elastic Wave Control Via Mechanical‐Acoustic Interaction in Bistable Metamaterials
A mechanically programmable metamaterial based on mechanical‐acoustic interaction enables reconfigurable elastic wave control through bistable state switching. Spatial encoding of peak and valley states tunes band structures and transmission, achieving low‐frequency vibration suppression, waveguiding, and energy localization.

Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
