Abstract: A micropump that pumps liquid using electrothermally-induced flow is described, along with a corresponding self-regulating pump and infusion pump. The micropump has applications in microfluidic systems, such as biochips. The self-regulating infusion pump is useful for administration of large and small volumes of liquids such as drugs to patients and can be designed for a wide range of flow rates by combining multiple micropumps in one infusion pump system. The micropump uses electrode sequences on opposing surfaces of a flow chamber that are staggered with respect to each other. The opposing surfaces include staggered electrodes that have the same phase and same electrode sequence. As such electrodes with the same phase are staggered and not eclipsed.

Abstract translation: 描述了使用电热诱导流体泵送液体的微型泵，以及相应的自调节泵和输液泵。 微型泵在微流体系统中具有应用，如生物芯片。 自调节输液泵可用于向患者施用大量和小体积的液体，例如药物，并且可以通过在一个输液泵系统中组合多个微泵来设计用于各种流量的流量。 微型泵使用相对于彼此交错的流动室的相对表面上的电极序列。 相对表面包括具有相同相位和相同电极序列的交错电极。 因为具有相同相位的电极是交错的并且不会被淹没。
