Title:
ELECTROSTATIC ACTUATOR
Document Type and Number:
Japanese Patent JP2005137079
Kind Code:
A
Abstract:

To provide an electrostatic actuator movable in an arbitrary direction by drive electrodes disposed in a matrix state and suitable for a mass production without loss of a power.

In the electrostatic actuator, a sheet-like moving element 2 is laid on a stator 4, and the moving element 2 is moved by a drive force by the interaction of a charge induced on the moving element 2 and a charge on the matrix-like drive electrode of the stator 4. A positive potential is applied from a positive power source circuit 14 to a drive electrode circuit 6 and a selecting electrode circuit 8, and a negative potential is applied from a positive power source circuit 16 to a driving electrode circuit 12 and a selecting electrode circuit 10, and the positive and negative potentials applied to the drive electrode are controlled by a control circuit 18.
