Improvement in Durability of Piezoelectric Stack Actuator.

open access: yesJournal 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.
