Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
Advanced Materials, EarlyView.This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Improvement in Durability of Piezoelectric Stack Actuator.
Journal of the Ceramic Society of Japan, 1999 A study of durability test was piezoelectric stack actuator having various values of Qm, Tc, Ec and bending strength. The high bending strength but low Ec stack showed a decrease of displacement and appeared cracks which occurred at the edge of positive side of PZT pellet and grown to the center of diameter and negative side.
