Micropumps play a significant role in fluid transportation system of μ-TAS. We propose a peristaltic micropump system composed of a microchannel made of silicon rubber. Bottom surface of the microchannel is deformed by the electrostatic attraction between upper and lower electrodes made of copper thin films. Since the pump has simple structure using the electrostatic thin film actuators without valves, the fabrication process is also as simple as just stacking organic films or layer on PMMA substrate. The micropump is suitable for low-cost disposable applications. We could observe clear deflection of the channel wall which is proportional to the a square of the applied voltage. In addition, we confirmed active motion of microbeads in the fluid by the peristaltic actuation of electrostatic force.
