    • Devices, systems, and methods for the precise dispensation of small volumes of liquids are presented. A fluid microdispenser comprises a liquid-filled tube, an actuator coupled to the tube, and a tip at one end of the tube. When the actuator applies an actuation pressure, a precise volume of liquid is ejected from the orifice of the tip. The orifice is manufactured to control the volume of liquid ejected by each actuation and, therefore, may have a diameter smaller than that of the liquid-filled tube. The invention comprises systems, methods, and devices so that the inner diameter of the liquid-filled tube is decreased (tapered) to that of the orifice so as to maximize transmission to the orifice of the pressure generated by the actuation stimulus. This enables the volume of liquid ejected by each stimulus to be reproducibly controlled by the amplitude of the actuation stimulus.
    • 提出了用于精确分配少量液体的装置,系统和方法。 流体微分配器包括充满液体的管,耦合到管的致动器和管的一端的尖端。 当致动器施加致动压力时,精确体积的液体从尖端的孔喷出。 制造孔口以控制由每次致动喷射的液体的体积,因此可以具有比液体填充管的直径更小的直径。 本发明包括系统,方法和装置,使得充满液体的管的内径减小(锥形)到孔口的内径,从而最大程度地使通过致动刺激产生的压力对孔的传递。 这使得可以通过致动刺激的振幅可再现地控制由每个刺激喷射的液体的体积。
