This paper reports on a wirelessly driven swimming micromachine and micro-screw pump with magnetically driven screw-type microactuators. Microscrews were fabricated using a magnetically modified photocurable polymer and microstereolithography. The microcrews were magnetized in a radial direction and inserted in capillaries filled with fluid. Rotating magnetic field was applied to them by electromagnetic coils located around the capillaries. The spiral structure of the microscrew converted the rotational motion into the propulsive force, and thereby the microscrew swam along the capillary. On the other hand, when the microscrew was trapped at a fixed location in the capillary and rotated, the microscrew pumped the fluid continuously.
