Abstract
An actuator component for a droplet ejection head; wherein said actuator component comprises a substrate and one or more strips of piezoelectric material fixedly attached to said substrate; wherein said one or more strips of piezoelectric material comprise one or more layers of piezoelectric material, and an array of fluid chambers defined within said one or more strips of piezoelectric material and extending in an array direction; wherein said actuator component further comprises one or more cover parts; wherein the or each cover part extends in said array direction and is fixedly attached to at least one of a side face of one of said strips of piezoelectric material and/or at least a portion of said substrate; and wherein said one or more cover parts comprise a plurality of openings so as to enable fluid to be supplied to selected ones of said fluid chambers through said openings. Associated methods of manufacturing an actuator component for a droplet ejection head are also provided.
