Abstract
An actuator comprises a laminate of interleaved layers of electrode plates and piezoelectric material; wherein an upper region (in use) of electrode plates is adapted when energized to effect deflections in up and down directions; a lower region of electrode plates is adapted when energized to effect deflections in up and down directions; and one or more further regions of electrode plates are adapted when energized to effect deflections in left and right directions.
