| Summary: | Bioactuators, biological motors in living systems, are promising for integration and functionalization of microsystems. We have developed a Ca
2+
‐driven microvalve powered by a contractile fiber, a stalk of
Vorticella
. Cells of
Vorticella convallaria
were trapped in designed microchambers. Stalks were self‐grown in the chambers and their reversible linear actuations were controlled by regulating the concentration of Ca
2+
. A cell body, connected to a stalk, opened and closed a microchannel by the contraction and extension of the stalk. The flow field in the chamber was characterized to further optimize the actuation performance. |
