摘要： A micro-fluidic pump comprises one or more channels having an array of resistive heaters, an inlet, outlet and a substrate as a heat sink and a means of cooling the device. The pump is operated with a fire-to-fire delay and/or a cycle-to-cycle delay to control the pumping rate and minimize heating of liquid inside the pump during its operation.

摘要： An ink composition for used in an inkjet printer is provided. The ink composition includes a carrier medium, a colorant, and a silicon doping agent. The silicon doping agent may include silicic acid, silicon dioxide, or silicates. This silicon-doped ink reduces and prevents the etching of the silicon based components of the printhead. Silicon-doped inks protect the printhead from damage, thus improving printhead reliability and increasing printhead service life.

摘要： A piezoelectric inkjet printhead is monolithically fabricated on a substrate. The printhead includes a plurality of cavities formed into the substrate, piezoelectric actuators disposed over the top of the cavities, a fluidic structure and an ink supply channel. The piezoelectric actuators are formed over the cavities using a sacrificial material which fills the cavities and is removed after the actuators are formed. The fluidic structure defines pressurizing chambers and channels connected to the ink supply channel. The fluidic structure has a plurality of nozzle holes formed on the top surface. The cavities are connected to either a venting channel formed from the backside of the substrate or a venting chamber formed inside the fluidic structures.

摘要： The disclosed invention relates to achieving micromachined piezoelectrically-actuated diaphragms. The piezoelectric diaphragm includes a central, inactive electrode free region and an annular shaped interdigitated electrode adjacent to the outer periphery of the central region. The diaphragm also may have an inactive annular, electrode free region and an active central, interdigitated electrode region. The diaphragms may be used in, such as, miniature pumps. The pumps may include a plurality of chambers to generate peristaltic pumping of fluids.
