Abstract
The present invention provides a method and apparatus for storing and retrieving information using the phenomenon of dielectrophoresis. First and second materials are contained within a housing, and a non-uniform electrical field is applied to the materials. The materials have different dielectric constants, and relative movement of the materials occurs as a result of dielectrophoretic forces resulting from the applied non-uniform field. Different positions of one of the materials within the housing correspond to stored information and varying the applied non-uniform field varies the position of the one material to change the corresponding information. A detector is provided to locate the position of the one material in the housing corresponding to the stored information to retrieve the information represented by that position.
