| 摘 要： | 设计了一种电渗驱动聚二甲基硅氧烷(polydimethyl siloxane,PDMS)薄膜式微泵,建立了该泵在理想情况下的数学模型。在实验室中设计并制作了样机,并在输入电压30 V、输入频率1.4 Hz时,得到最大的输出流量为133 μL/min(选用纯净水为测试液体)。为得到高性能的输出,通过实验找到一个占空比为30%的控制信号。通过一系列系统实验进一步验证:电渗驱动PDMS薄膜式微泵性能稳定、输出流量易于精确控制、不受输送药剂特性限制,适用于生化分析领域。 |

| Abstract: | A novel polydimethyl siloxane(PDMS) diaphram micropump was developed. A mathematical model was built for the micropump under the ideal condition. A prototype of the pump was designed and manufactured in the laboratory. It was found by experiment that a superior pumping performance was achieved at electroosmotic(EO) actuator voltage duty ratio of 30%. The maximum output of prototype is 133 μL/min(using pure water as working liquid)under an input voltage of 30 V and an exciting frequency of 1.4 Hz. A series of experiments demonstrated that the electroosmotically actuated PDMS diaphram micropump is characterized by good working stability, easy to control its flow output and independent of property of the delivered drug, being suitable for the biochemical analysis system. |
