Abstract
The present invention is a method and apparatus for achieving high work output per unit volume in micro-robotic actuators, and in particular TiNi actuators. Such actuators are attractive as a means of powering nano-robotic movement, and are being developed for manipulation of structures at near the molecular scale. In these very small devices (one micron scale), one means of delivery of energy is by electron beams. Movement of mechanical structures a few microns in extent has been demonstrated in a scanning electron microscope. Results of these and subsequent experiments will be described, with a description of potential structures for fabricating moving a microscopic x-y stage.
