Abstract: An inkjet print head for expelling a droplet of a fluid through a nozzle orifice comprises a fluid channel for holding a channel amount of fluid, the fluid channel comprising a pressure chamber in fluid communication with the nozzle orifice and a piezo actuator. The piezo actuator comprises an active piezo stack, which stack comprises a first electrode, a second electrode, and a piezo-material layer arranged between the first and the second electrode, and the piezo actuator comprises a membrane having a first side and a second side, the second side being opposite to the first side. The active piezo stack is provided at the first side and the pressure chamber at the second side such that the membrane forms a flexible wall of the pressure chamber. The fluid channel, when holding the channel amount of fluid, has a fluid compliance and the piezo actuator has an actuator compliance. In accordance with the present invention, the actuator compliance is larger than the fluid channel compliance such to have a high energy coupling efficiency and consequently a low power dissipation.
