Abstract
An electrostatic liquid-ejection actuation mechanism includes a membrane, a frame, and one or more deformable beams. The frame has two sides and a number of cross members that are non-parallel to the two sides. The two sides and the cross members define one or more areas individually corresponding to one or more liquid chambers. The deformable beams are disposed between the membrane and the frame. The deformable beams individually correspond to the liquid chambers, and define a number of slits. Each slit is adjacent to one of the two sides of the frame. The deformable beams have a width that is less than a width of the liquid chambers, due at least to the slits.
