摘要

由於微機電系統的發展，以致於人們必須發展出對微小物體的微細操作方法和策略。例如：生醫科技中的細胞操作，還是手術器材的微型化。資訊產品的小型化、薄型化，導致各部位的元件必須盡量縮小。不論要組裝還是操作這些微小物體，就必須要有更能精準定位的微夾具。精準定位就是撓性微夾具設計的重點，挾持力的效能，也是影響微夾具的可用性。
拓樸最佳化的設計中，最早是用在桁架的排列設計上。而撓性結構，是用彈性的變形來完成能量運輸，而不是運用傳統機構的接合方式來完成受力後的變形與滑動，也就是撓性機構是一個一體成形的結構，所以可以利用2D的拓樸最佳化概念來設計撓性微夾具，以完成新型的設計或是舊型效能的改善。

Due to the development of micro electro mechanical systems, it is necessary for people the microscopic operation methods and strategies in response to the miniature operation. For example, about the cellular operation for biomedical technology, the microscopical designs for surgery devices, and the miniaturized and slimmed it products, all of the components within shall be downsized as best as we can. No matter the operation or the assembly for the said microscopical miniatures, they actually require the micro-gripper with more precise positioning. However, precise positioning accuracy is exactly the very important for the design of compliant micro-gripper. Thereafter, the efficiency of clamping force can also critically affect the usability of the said micro-gripper.
Within the topological optimal design, it is firstly used on the design of truss arrangement. Also, the compliant structure finishes the energy transmission through the flexibility deformation rather than the deformation and sliding after burdened with force by using the linkage of traditional mechanisms. Namely, the compliant structure is also a solid type structure; thus, we can adopt the notion of 2D topological optimization to design the compliant micro-gripper so that we can reach the design for new models or the improvement for old models.
