摘要:
A fluid ejection device that can be used for inkjet heads is described. A large actuator with a small stroke in combination with hydraulic pressure transfer by means of essentially relatively incompressible fluid is used in order to generate a large stroke of a small membrane. Further the ink is ejected during the actuation phase of the actuator enabling a better control of the droplet dynamics.

摘要:
The invention relates to a micro electromechanical device (1′) for tilting a body (2) in two degrees of freedom comprising a carrier element (3) and a membrane (4), the body (2) being connected via the membrane (4) to the carrier element (3), wherein the body (2) and the carrier element (3) each comprise at least one electrode (5,6). The body (2) is tilted by means of electrostatic forces (7) between the at least one electrode (5) of the body (2) and the at least one electrode (6) of the carrier element (3) by an application of a voltage (V1,V2) to said electrodes (5,6) from a voltage source.
