Abstract:
1. A fluid-jet precision-dispensing device comprising: a first layer defining a first chamber; a second layer defining a second chamber below the first chamber, the second chamber fluidically coupled to the first chamber, the second chamber having a lesser height than the first chamber and a greater width than the first chamber; one or more actuators within the second layer; one or more first holes within the second layer and opposite the one or more actuators, the first holes adapted to pass fluid therethrough upon ejection by the actuators during usage of the device to precisely dispense the fluid at accurately specified locations; and, one or more second holes within the second layer, the second holes adapted to not pass the fluid therethrough during usage of the device to precisely dispense the fluid at the accurately specified locations, the second holes further adapted to one or more of: wherein the second holes are sized and/or shaped to ensure that a critical pressure at each second hole has an absolute value greater than an absolute value of a backpressure at each second hole during the usage of the device.
