Patent ID: 7023124

Claim:
A microactuator array comprising: a plurality of first terminals equal in number to a first number; a plurality of second terminals equal in number to a second number; and a plurality of microactuators equal in number to the product of the first number and the second number, the plurality of microactuators disposed in a lattice in a two-dimensional plane, wherein each microactuator comprises a fixed electrode and a movable electrode that is movable with respect to the fixed electrode by electrostatic force, wherein each first terminal is electrically connected to the fixed electrodes of microactuators equal in number to the second number, wherein each second terminal is electrically connected to the movable electrodes of microactuators equal in number to the first number, wherein the first terminals are not connected to any of the second terminals, wherein one end of each microactuator is fixed at the fixed electrode, and the other end of each microactuator is movable with respect to the fixed electrode and has a beam section where the movable electrode is disposed, and wherein each beam section is two-dimensionally bent and a portion of each beam section is two-dimensionally superimposed on the beam section of an adjacent microactuator.
