“Simple Actuator” is an actuator with the piezo-electric element integrated in its elastic hinge mechanism.
Tapped holes help fixing and removal while the travel guide helps achieving highly linear movement.
No built-in displacement sensor.
Displacement of piezo-electric element, Piezo Driver
Hysteresis and Creeping
In opne loop operations, hysteresis and creeping occur.
Piezo driver
Low-noise driver for driving a simple actuator.
There are 3 types in accordance with output current magnitude.

Applications
•Integration of piezo-electric actuator
•Fine adjustment in nanometers
•In experiments and R&D
•Smooth operations with no anchoring or slippage (stick slip)

| Displacement magnification mechanism |
– Several times longer stroke than that of single piezo-electric element.
– As it is horizontally mounted and displaced in the perpendicular directions, integration with thinner wall is possible.
