Abstract
The electromechanical translation apparatus includes a translation drive assembly driven by front and rear piezoelectric clamping members coupled together with central extension piezoelectric members, which negotiate an elongated stationary channel. The translation drive assembly may directly carry an object for precise linear positioning in one dimension, or may carry a movable channel which in turn may be translated along an axis perpendicular to the direction of the stationary channel, so that an object placed upon the movable channel can be precisely positioned in two dimensions.
