Natural cellular activities are increasingly exploited for micro analytical systems, biochemical reactors. We describe novel use of pulsating heart cells as mechanical microactuators. In this study, bio microactuation was demonstrated by driving a micro tube type membrane using regular contractile behaviors of attached cardiomyocytes. A thin tube which thickness is about 15μm was handmade. A deformation by contracting force was observed and it displacement was about 29μm. This cell microactuator system performance is sufficient to change fundamental design concepts for microfluidic devices to exploit cell behaviors in on-chip processing, and manipulations.
