Fluid displacement mechanism

Image Number 2 for United States Patent #8031408.

A fluid displacement mechanism is disclosed. In an embodiment, first and second cavities are separated by a flexible membrane. The first cavity contains a non-conductive fluid and the second cavity contains a conductive fluid. First and second electrodes are positioned in the first and second cavities respectively such that the application of a voltage between the electrodes causes movement of the membrane by the build up of an electrostatic charge between the membrane and first electrode.
