    Abstract: A print head comprises a pressure chamber in fluid communication with a nozzle and an actuator structure in operative communication with the pressure chamber for generating a pressure wave in the pressure chamber. The actuator structure comprises a membrane, wherein a first surface of the membrane forms a flexible wall of the pressure chamber and a piezo actuator, wherein the piezo actuator is arranged on a second surface of the membrane, the second surface being opposite of the first surface, such that the membrane is deformed at the position of the piezo actuator upon actuation of the piezo actuator. In the print head, the membrane is pivotably clamped between a first structure layer and a second structure layer such that the membrane pivots at the location of clamping upon deformation of the membrane due to actuation of the piezo actuator.

    Abstract: A substrate plate is provided for at least one MEMS device to be mounted thereon. The MEMS device has a certain footprint on the substrate plate, and the substrate plate has a pattern of electrically conductive leads to be connected to electric components of the MEMS device. The pattern forms contact pads within the footprint of the MEMS device and includes at least one lead structure that extends on the substrate plate outside of the footprint of the MEMS device and connects a number of the contact pads to an extra contact pad. The lead structure is a shunt bar that interconnects a plurality of contact pads of the MEMS device and is arranged to be removed by means of a dicing cut separating the substrate plate into a plurality of chip-sized units. At least a major part of the extra contact pad is formed within the footprint of one of the MEMS devices.

    Abstract: A droplet ejection device includes a pressure chamber; a nozzle orifice arranged in fluid connection with the pressure chamber; an actuator system for generating a pressure wave in a liquid present in the pressure chamber; and an obstruction member arranged in the pressure chamber in a position opposite to the nozzle orifice. The obstruction member comprises a first surface facing the nozzle orifice and rigidly coupled to a wall of the pressure chamber via a support. The support is arranged near the first surface of the obstruction member. The droplet ejection device according to the present invention may further comprise a structured nozzle inflow means which provides a gradual transition from the hollow shaped liquid passage to the nozzle orifice. The droplet ejection device prevents or at least mitigates air entrapment in dead volumes present in the interior of the droplet ejection device.
