__Summary__:

The objective of this paper is to present the state-of-the-art of
precision actuators for space application in the United States.
This report is based upon information available to the author and
not on a comprehensive search of all the developments in the US.
Precision actuators are those with submicron resolution and often
limited to less than about .2% strain of the actuator material.
Most of the actuators are those associate with Adaptive Structures.
One definition of Adaptive Structures are systems whose geometric
and physical structural characteristics can be beneficially
‘modified to meet mission requirements either through remote
“commands or automatically in response to internal or external
stimulations. Actuators, sensors and control systems are directly
integrated into the structure.
