Abstract
A new technique has been developed for poling long PZT fibers by advancing the fibers along two electrical contacts maintained at the required potential difference. Two ways of maintaining the electrical contact with the ceramic are described, leading to piezoelectric d33 coefficients of 400 to 450×10−12 C/N in poled fibers of PZT‐501A. Pre‐poled fibers can be used in fabricating ceramic‐polymer composites such as triple‐pillar configurations with piezoelectric fibers oriented in three perpendicular directions.
