Philips Electronics Assigned Patent for Electrostatic Actuator for Ink Jet Heads

Strategic Insights -

Philips Electronics, Eindhoven, The Netherlands, has been granted a patent (7,942,501) for an electrostatic actuator for ink jet heads. The patent, developed by five co-inventors, aims to provide high-pressure inkjet heads for high-quality printing. The electrostatic actuator is designed to compress the ink in a chamber with an opening, allowing for high pressure to be applied.

The patent abstract states that the maximum pressure that can be applied is adaptable by adjusting the ratio of the overlapping area of the two electrodes to the area of the membrane covering the chamber with the ink. The invention also mentions the use of the head to eject a liquid drug in an injection system.
