    • A microfluidic control valve (100) comprising a dielectric structure (105) defining at least one cavity (260) therein. An electroactive material (305), such as an electroactive polymer, is disposed in a portion of the cavity. The electroactive material is operable between a first state in which a dimension of the electroactive material has a first value and a second state in which the dimension has a second value. Two conductors (240, 250) can be included for applying a voltage potential across the electroactive material to change the electroactive material between the first state and the second state. A first fluidic port (310) can be located proximate to the electroactive material such that a fluid flows through the first fluidic port when the electroactive material is in the first state, and the electroactive material at least partially blocks the first fluidic port when the electroactive material is in the second state.
    • 一种微流控制阀(100),包括在其中限定至少一个空腔(260)的电介质结构(105)。 诸如电活性聚合物的电活性材料(305)设置在空腔的一部分中。 电活性材料可在其中电活性材料的尺寸具有第一值的第一状态和尺寸具有第二值的第二状态之间操作。 可以包括两个导体(240,250),用于跨电活性材料施加电压电位,以在第一状态和第二状态之间改变电活性材料。 第一流体端口(310)可以位于电活性材料附近,使得当电活性材料处于第一状态时,流体流过第一流体端口,并且当电活化材料处于第一状态时,电活性材料至少部分地阻塞第一流体端口 材料处于第二状态。

    • A fluid pump (100) having a homopolar motor (110). The homopolar motor includes a rotatable disk (115) defining at least one impeller (120). The impeller can include an orifice within the rotatable disk. The rotatable disk can be at least partially disposed within a cavity (145) defined in the substrate (105), such as a ceramic substrate, a liquid crystal polymer substrate, or a semiconductor substrate. A closed loop control circuit (335) can be included to control the rotational speed of the rotatable disk. For example, the control circuit can control a voltage source or a current source that applies voltage across the rotatable disk. The control circuit also can control a strength of a magnet (310) that applies a magnetic field (305) substantially aligned with an axis or rotation (155) of the rotatable disk.
    • 具有单极电动机(110)的流体泵(100)。 单极电动机包括限定至少一个叶轮(120)的可旋转盘(115)。 叶轮可以包括在可旋转盘内的孔口。 可旋转盘可以至少部分地设置在限定在基板(105)中的空腔(145)内,例如陶瓷基板,液晶聚合物基板或半导体基板。 可以包括闭环控制电路(335)以控制可旋转盘的转速。 例如,控制电路可以控制在可旋转盘上施加电压的电压源或电流源。 控制电路还可以控制施加与可旋转盘的轴线或旋转(155)基本对齐的磁场(305)的磁体(310)的强度。
