Design and Analysis of a 6-DOF Monolithic Nanopositioning Stage

Key Engineering Materials, 2010
A 6-DOF monolithic nanopositioning stage is developed for three coordinate measuring machines (CMM) with nanometer resolution. The stage consists of a monolithic flexure hinge mechanism, six piezoelectric actuators and six fiber-optic displacement sensors. A mathematical model of the constraint optimization problem is presented.

A Long-Stroke Nanopositioning Stage With Annular Flexure Guides

IEEE/ASME Transactions on Mechatronics, 2022
This paper presents a long stroke nanopositioning stage supported with annular flexure guides to be used in high precision optical instruments. Firstly, the structure of the novel annular flexure guide and the positioning stage is proposed. Because of the symmetric configuration of the flexure guide, large motion range, high linearity, and high ...

Maglev 6-DOF Stage for Nanopositioning

Dynamic Systems and Control, Volumes 1 and 2, 2003
This paper presents a novel magnetically levitated (maglev) stage with nanoscale positioning capability in all six degrees of freedom (DOFs). The key aspect of this device is that its single moving part has no mechanical contact with its stationary base, which leads to no mechanical friction and stiction, and no wear particle generation.
