The purpose of this study is to develop a millimeter scale two degree of freedom planar actuation mechanism (XY stage) with flexure hinges that can generate micrometer scale motion at high frequencies. To amplify the micro scale motion in X and Y directions, two identical levers are used. According to the analytical and computational results, a prototype is developed for validation. Piezoelectric actuators are used in the system because of their compactness and large force capacity. The levers in the XY stage are topologically optimized so that the first resonance frequency of the system is maximized, which enlarges the operation range of the system.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
