Latest and Unique Methods for Actuation

Potential actuator configurations capable of generating higher actuation forces are discussed. Preliminary studies performed by the author on various actuators indicate that the widely used parallel-plate (PP) configuration may generate an actuation force by an order of magnitude greater than that of the interdigitated configuration, in addition to minimum cost and complexity. This leads to a conclusion that a PP actuator configuration is best suited for applications demanding a large output force over small displacements as in the case of hard-disk drives (HDDs).
