    摘要: A droplet generator is provided that is particularly adapted for generating micro droplets of ink on demand in an inkjet printhead having a plurality of nozzles. The droplet generator includes a droplet separator formed from the combination of a droplet assistor and a droplet initiator. The droplet assistor is coupled to ink in each of the nozzles and functions to lower the amount of energy necessary for an ink droplet to form and separate from an ink meniscus extending across the nozzle outlet. The droplet assistor may be, for example, a heater or surfactant supply mechanism for lowering the surface tension of the ink meniscus. Alternatively, the droplet assistor may be a mechanical oscillator such as a piezoelectric transducer that generates oscillations in the ink sufficient to periodically form convex ink menisci across the nozzle outlets, but insufficient to cause ink droplets to separate from the outlets. The droplet initiator cooperates with the droplet assistor and selectively causes an ink droplet to form and separate from the ink meniscus. The droplet initiator may be, for example, a thermally-actuated paddle. The droplet separator increases the speed and accuracy of ink micro droplets expelled from the printhead nozzles.

    摘要: A printhead includes a substrate, a filter membrane structure, and a liquid source. A first portion of the substrate defines a plurality of nozzles. A second portion of the substrate defines a plurality of liquid chambers. Each liquid chamber of the plurality of liquid chambers is in fluid communication with a respective one of the plurality of nozzles. The filter membrane structure is in contact with the second portion of the substrate. Each liquid chamber of the plurality of liquid chambers is in fluid communication with a distinct portion of the filter membrane structure. The filter membrane structure includes a polymeric material layer. The liquid source provides liquid under pressure through the filter membrane structure. The pressure is sufficient to jet an individual stream of the liquid through each nozzle of the plurality of nozzles after the liquid flows through the filter membrane structure.

    摘要: A thermal actuator for a micro-electromechanical device is disclosed. The thermal actuator includes a base element and a movable element extending from the base element and residing at a first position. The movable element includes a barrier layer constructed of a barrier material having low thermal conductivity material, bonded between a first layer and a second layer; wherein the first layer is constructed of a first material having a high coefficient of thermal expansion and the second layer is constructed of a second material having a high thermal conductivity and a high Young's modulus. An apparatus is provided adapted to apply a heat pulse directly to the first layer, causing a thermal expansion of the first layer relative to the second layer and deflection of the movable element to a second position.
