摘要： A micro-electromechanical systems (MEMS) device includes bottom and top capacitive plates, such that a capacitor is definable therebetween. A mechanism is electrostatically movably disposed between the bottom and top capacitive plates. One or more flexures are movably disposed between the bottom capacitive plate and the mechanism, and having distance stops between the bottom capacitive plate and the mechanism corresponding to maximum downward movement. The MEMS device includes one or more electrodes of the bottom capacitive plate corresponding to the flexures. Energizing different of the electrodes causes the flexures to move to different of the distance stops, causing the mechanism to move to different positions between the bottom and top capacitive plates.

摘要： A fluid ejection device includes a fluid chamber having a first sidewall and a second sidewall, a flexible membrane extended over the fluid chamber and supported at an end of the first sidewall and an end of the second sidewall, an actuator provided on the flexible membrane, a first gap provided between the flexible membrane and the end of the first sidewall, and a second gap provided between the flexible membrane and the end of the second sidewall, and compliant material provided within the first gap and within the second gap. As such, the actuator is adapted to deflect the flexible membrane relative to the fluid chamber.

摘要： In one embodiment, a fluid ejector structure includes: a chamber for containing a fluid; a flexible membrane forming one wall of the chamber; a plurality of piezoelectric elements; a backing operatively connected to the piezoelectric elements such that an expansion and/or contraction of a piezoelectric element causes the piezoelectric element to bend; a rigid plate overlaying a center portion of the membrane; a post coupling the piezoelectric elements to the plate through the backing such that a movement of each piezoelectric element toward the chamber is transmitted to the plate through the post. The plate is configured to transmit movement of the post to the membrane in a rigid, or substantially rigid, piston-like manner.

摘要： A piezoelectric printhead and related methods provide a first metallic electrode and a second metallic electrode deposited over a top surface and a bottom surface, respectively, of a piezoceramic plate. The second electrode is segmented into a plurality of electrode segments. A diaphragm is positioned over a plurality of pressure chambers, where the diaphragm includes a conductor positioned over each chamber. The piezoceramic plate is attached to the diaphragm such that each conductor on the diaphragm faces multiple electrode segments.

摘要： 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.
