摘要：
A method of polarizing a portion of a monolithic piezoelectric actuator element for use in droplet deposition apparatus where the element has first and second portions, includes the steps of placing the first portion of the element at an equipotential and generating a polarizing electric field across the second portion between said first portion and a further conducting layer.
