摘要：

The work presents a novel magnetostrictive micro-gripper driven by iron-gallium alloy (Galfenol) composite cantilever beam. The design and operation principles of the given micro-gripper are first introduced. Then, we analyze the magnetic distribution and the jaw displacement of the micro-gripper by theoretical simulations. The performance of magnetostrictive micro-gripper has been tested using the multilevel driving strategy to eliminate the vibration. The proposed micro-gripper can grasp micro-target with a maximum gap of 250 mu m, and the maximum exciting current of 1 A. The experimental results demonstrate that the proposed micro-gripper has a simple structure and fast response, suitable for micromanipulation and micro-assembly applications.
