Abstract

The ultimate spin-off of the proposed research is the development of aall-optical smart composite material technology in which the smart matial is made from a highly interconected association of mesoscale all-oical photomechanical devices. Such devices are unique because they opate without electronics: sensors (that encode stress to light), logicthat manipulates light) and photomechanical actuation (in which light uses a material to change shape) are all part of a monolithic device. urthermore, because all these functions are built into a single unit, ey can be easily miniaturized. The proposed research is to build a hi precision miniaturized photomechanical vibration suppressor, to charaerize the suppressor, and to attach it to a platform to study its acti damping effects on the platform. These studies would lay the foundatn for developing vibration-free platforms that are composed of many emdded suppressors. Such materials would operate at high speeds, are imne to electromagnetic interference, are safe in explosive environmentsare flexible by virtue of easy reprogrammability, and owing to their hh levels of interconnectedness, highly intelligent. Benefits: A vibration-stabilized platform would be used in applications that reqre high mechanical stability. Examples of applications include vibratn stabilized optical tables, scanning tunneling microscopes (optical a electron), and precision manufacturing platforms. A mesoscale unit c also be used as a sensor that is highly sensitive to abnormal vibrati signatures: an indicator of imminent structural or equipment failure
