微泵是微流体系统和生物传感系统的重要组成部分。特别地，用于微全分析系统的微型泵以高精度的微流量输送流体。此外，在需要运输各种类型的药物的情况下，还需要它们来运输高粘度流体。因此，为了实现能够以微流量输送溶液的微型泵，有必要开发具有简单机构的高精度微变形致动器。本文报道的导电聚合物软致动器，由于电化学氧化和还原，分别广泛开放和完全关闭。在其内部布置有阳离子驱动层的软致动器的打开和关闭运动变大，因为布置在外部的阴离子驱动层是主要驱动器。我们开发了一种微泵驱动的导电聚合物软致动器，打开和关闭。所研制的微泵虽然不含阀门，但可实现流体的单向无回流输送。新研制的导电聚合物软致动器驱动的微泵，通过两个软致动器的开闭，可以实现流体的单向无回流输送。此外，更广泛的流量范围和更大的最大输送头获得使用新开发的微型泵。微泵的能量消耗率明显低于传统的微泵。版权所有© 2010化学工业协会
Micropumps are essential components of microfluidic systems and biosensing systems. In particular, micropumps used for micro total analysis systems transport fluids at a microflow rate with high precision. Moreover, they are also needed to transport high-viscosity fluids in cases where there are various types of drugs to be transported. Therefore, in order to realize a micropump that can transport solutions at a microflow rate, it is necessary to develop a high-precision microdeformable actuator with a simple mechanism. The conducting polymer soft actuator reported here opens widely and closes completely as a result of electrochemical oxidation and reduction, respectively. The opening and closing movement of the soft actuator, inside which the cation-driven layer is arranged, becomes large because the anion-driven layer that is arranged outside is the predominant driver. We developed a micropump driven by a conducting polymer soft actuator that opens and closes. Although the developed micropump contains no valve, the micropump can transport fluids in one direction without backflow. The newly developed micropump driven by the conducting polymer soft actuator can transport fluids in one direction without backflow by the opening and closing of two soft actuators. Furthermore, a wider range of flow rates and greater maximum delivery heads are obtained using the newly developed micropump. The energy consumption rate of the micropump is markedly lower than those of conventional micropumps. Copyright © 2010 Society of Chemical Industry
