チューブ型生物を用いたバイオアクチュエータによるピストン型マイクロポンプの作製

We created bio-actuated piston micro pump using earthworm as a bio-actuated micro piston. We first designed cylinder channel that earthworm reciprocate to move fluids. It is prepared with micro fluidic chip. Then we demonstrated fluid actuation by movement of earthworm in cylinder channel. We estimated the flow rate from tracking the micro spherical beads. The flow rate was 0.23 µL min^-1. It was equivalent to current bio-actuated micro pumps. Finally, we show the driving of the valve by earthworm in micro fluidic chip with planar check valve. The check valve was moved 31.4 µm. It was found that the bio-actuated micro piston pump had high space efficiency and high pressure potential.
