Title:
PROGRAMMABLE ACTUATOR AND PROGRAMMING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2011044556
Kind Code:
A
Abstract:

To provide an electrostatic type MEMS actuator having a program function.

The programmable actuator includes a movable part 1 having a first drive electrode 3A; a second drive electrode 3B opposite to the first drive electrode 3A and having first and second parts 5a, 5b; a first drive circuit 6a for allowing the movable part 1 to operate a plurality of times, in a state where both the electrodes are not in electrical contact with each other, by generating a first potential difference between the first part 5a of the second drive electrode 3B and the first drive electrode 3A; and a second drive circuit 6b for fixing the movable part 1, in a state where both the electrodes are in electrical contact with each other, by generating a second potential difference between a second part 5b of the second drive electrode 3B and the first drive electrode 3A.
