Abstract
Realizing out-of-plane actuation in micro-electro-mechanical systems (MEMS) is still a challenging task. In this paper, the design, fabrication methods and experimental results for a MEMS-based out-of-plane motion stage is presented based on bulk micromachining technologies. This stage is electro thermally actuated for out-of-plane motion by incorporating beams with step features. The fabricated motion stage has demonstrated displacements of 85 um with 0.4 um/mA rates and generated up to 11.8 mN forces with stiffness of 138.8 N/m. These properties obtained from the presented stage are in a similar level to in-plane motion stages which improve its usefulness when used in collaboration with in-plane motion stages.Citation
