Abstract
An electrostatic inkjet head providing high pressure to ink in order to enable high quality printing. The electrostatic actuator providing the pressure to the membrane () compressing the ink in a chamber () with an opening () is characterized by an overlapping area of the actuation electrode () and the moveable electrode () not determined by the area of the membrane () covering the chamber () with the ink. The maximum pressure that can be applied can be adapted by means of the ratio of the overlapping area () of the two electrodes and the area () of the membrane () covering the chamber () with the ink. Use of said head to eject a liquid drug used in an injection system.
