側壁駆動型蠕動マイクロポンプによるビジュアルフィードバックを用いた粒子捕捉

抄録

This study proposes a method for manipulating a particle in a microchannel using a sidewall-driven peristaltic micropump. The sidewall-driven peristaltic micropump is actuated by air pressure and can continuously push fluid in a microchannel by deforming the sidewall of the channel to generate peristaltic motion. By varying the pressure of the air supply, the velocity of the flow produced by the micropump can be varied. By changing the direction of peristaltic motion and the driving pressure the micropump can control the flow rate with high precision. We constructed a visual feedback control system using images in the microchannel to control the position of a microbead. It was confirmed that the precise positioning of a particle could be performed automatically.
