Rotation of micro gear by moving bacteria sheet

Abstract

In this paper, we established the driving systems for micro structures by using surface swarming of Vibrio alginolyticus. First, we succeeded in causing rotational movement using ratchet shape micro channel. Next, To rectify rotational movement, we fabricated center prior in the micro channel. We succeeded in smooth rotational movement using this new design micro channel. Furthermore, we succeeded in driving micro gear in the micro channel.
