Abstract

A fluid displacement device (100) having a homopolar motor (110). The homopolar motor includes a rotatable disk (115) with at least one fluid displacement structure (120) disposed thereon. The fluid displacement structure can be a blade. The rotatable disk can be disposed within a cavity (145) defined in a substrate (105), such as a ceramic substrate, a liquid crystal polymer substrate, or a semiconductor substrate. A closed loop control circuit (235) can be included to control the rotational speed of the rotatable disk. For example, the control circuit can control a voltage source or a current source that applies voltage across the rotatable disk. The control circuit also can control a strength of a magnet (210) that applies a magnetic field (205) substantially aligned with an axis or rotation (155) of the rotatable disk.

Claims (10)

1. A fluid displacement device comprising:
a homopolar motor comprising a rotatable disk; and at least one fluid displacement structure provided on said rotatable disk.
2. The fluid displacement device of claim 1 wherein said rotatable disk is disposed on a substrate.
3. The fluid displacement device of claim 2 wherein said rotatable disk is at least partially disposed within a cavity defined in said substrate.
4. The fluid displacement device of claim 2 wherein said substrate is selected from the group consisting of a ceramic substrate, a liquid crystal polymer substrate, and a semiconductor substrate.
5. The fluid displacement device of claim 1 further comprising a closed loop control circuit to control a rotational speed of said rotatable disk.
6. The fluid displacement device of claim 5 wherein said closed loop control circuit controls at least one of a voltage source and a current source that apply voltage across said rotatable disk.
7. The fluid displacement device of claim 5 wherein said closed loop control circuit controls a strength of a magnet that applies a magnetic field substantially aligned with an axis of rotation of said rotatable disk.
8. A method for displacing fluid comprising:
positioning within a fluid a rotable disk having at least one fluid displacement structure disposed thereon; and applying a voltage across a central portion of the rotatable disk and a radial edge portion of the rotatable disk in the presence of a magnetic field substantially aligned with an axis of rotation of the rotatable disk.
9. The method according to claim 8 further comprising selectively controlling a rotational speed of the rotatable disk to vary a fluid displacement rate.
10. The method according to claim 9 wherein said step of selectively controlling a rotational speed further comprises controlling a strength of the magnetic field.
