Modelling of Compliant Micro-motion Stages with Flexure Hinges

Yuen Kuan Yong and Tien-Fu Lu

Keywords: Micro-motion stage, compliant Mechanism, flexure Hinge

(Commenced: 31-Jan-2003,Concluded: 31-Jan-2008)

This research project focuses on the methodology of deriving simple but effective kinematic and static models of compliant micro-motion stages which accurately represent the real system. The models will benefit the design and optimisation processes where a few micro-motion stage designs can be analysed quickly without the needs of using any commercially available finite-element software. A 3-DOF micro-motion stage, which is designed for the positioning of samples in a Scanning-Electron-Microscope (SEM), is selected as an example to develop this methodology.

  • 3-DOF compliant micro-motion stages (6 Images)
    This collection of images show two different prototypes of 3-DOF compliant micro-motion stages. The first prototype is used for the manipulation of biological cell during the IVF process. The second prototype is designed for the positioning of samples in a Scanning-Electron-Microscope (SEM).
