    摘要: A fluid discharge head includes a fluid chamber filled with ink; a discharge opening configured to discharge a droplet of ink from the fluid chamber; a plurality of piezoelectric elements configured as displacement generating units to provide kinetic energy to the ink for the discharge of the ink droplet; and a vibrating plate forming a part of the fluid chamber and connected to the piezoelectric elements, the vibrating plate being configured to transmit a displacement generated by the piezoelectric elements to the ink in the fluid chamber. The vibrating plate includes vibrating portions for the respective the piezoelectric elements. The vibrating portions are configured to be independently displaced for the corresponding piezoelectric elements, and at least one of the piezoelectric elements is configured as a pressure detecting unit to detect an ink pressure in the fluid chamber.

    摘要: Disclosed is an electromechanical transducer element that includes an electromechanical transducer film formed of a complex oxide (PZT) including lead (Pb), zirconium (Zr), and titanium (Ti). The electromechanical transducer film is formed by laminating plural PZT thin films until a thickness of the formed electromechanical transducer film becomes a predetermined thickness. When an atomic weight ratio (Pb/(Zr+Ti)) of average Pb included in the formed electromechanical transducer film is denoted by Pb(avg) and an atomic weight ratio (Pb/(Zr+Ti)) of Pb in any one of laminate interfaces of the plural PZT thin films is denoted by Pb(interface), the Pb(avg) is greater than or equal to 100 atomic percentage (at %) and less than or equal to 110 atomic percentage (at %), and a fluctuation ratio ΔPb=Pb(avg)−Pb(interface) of Pb in the laminate interface is less than or equal to 20 percent.
