Title: Piezoelectric actuator and liquid droplet injection unit

Filed: 2002-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric actuator capable of imparting a sufficient deforming amount to a piezoelectric material plate even at a low drive voltage and having good energy efficiency, and to provide a liquid droplet injection unit. SOLUTION: A voltage is applied between an electrode 3 at a center of a liquid chamber 5 and an electrode 2 above partition walls 61. Since a direction of an electric field E generated at this time coincides with a polarizing direction A of the piezoelectric material plate 1, the plate 1 tends to elongate in a direction along a surface in a piezoelectric longitudinal effect, that is, a direct mode. However, since both ends of a part of the plate 1 tending to elongate are fixed to partition walls 61, 61, a part of the plate 1 is flexed to be deformed (that is, buckled to be deformed) to the side having no cutout 1A between the walls 61 and 61, and a volume of the chamber 5 is reduced. Thus, an ink 10 is injected from a nozzle 8.
