Abstract

Contemplated printheads include a piezoelectric material in which a channel is formed across the piezoelectric material to thereby create at least part of the nozzle through which ink is expelled from the inside of the printhead to the outside. Contemplated nozzles may be configured as cylindrical elements or ring-shape elements. Consequently, application of a voltage across the piezoelectric channel may result in constriction of the cylindrical element or convex/concave deformation of the ring-shape element. Most preferably, the piezoelectric material, conductive traces, and supporting structures are applied from a liquid phase to a carrier, and shaped using photolithographic methods.
