A pronounced manifestation of a new electric-to-mechanical coupling phenomenon in the ferroelectric ceramic PZT 65/35

Summary In this paper, we present experimental results to show a pronounced manifestation of a new electric-to-mechanical coupling phenomenon in the ferroelectric ceramic PZT 65/35. This phenomenon has been previously reported in the electro-optic ceramic PLZT 7/65/35. We believe that it is also present in other ferroelectric materials. In particular, experimental evidence indicates that this coupling phenomenon during the process of poling results in flexural mechanical displacements which are much larger than the combined changes in thickness due to domain switching and conventional piezoelectric coupling. Its influence also increases markedly with remanent polarization.With 1 FigureThis paper is dedicated to the memory of Professor Aris Phillips whom I have had the extreme privilege of knowing.
