本文提出了一种创新的驱动方法，用于磁驱动微工具，以实现精确的定位控制，同时保持来自商业化的永磁体的高功率输出。为了减小微工具的摩擦力，提出了一种使用永磁体的有效驱动方法，永磁体的轴线与驱动方向平行。与传统方法相比，定位精度提高了五倍，响应速度比驱动级快十倍。此外，该方法已被扩展到两个自由度的运动，和磁驱动的微工具的性能进行了实验验证卵母细胞操作。(c)2010年美国物理学会。[doi：10.1063/1.3459040]
This paper presents an innovative driving method for a magnetically driven microtool to achieve precise positioning control while maintaining a high power output derived from commercialized permanent magnets. An effective driving methodology using permanent magnets, whose axes are parallel to driving direction, is applied to reduce friction force on the microtool. The positioning accuracy improves by five times and the response speed becomes ten times faster against the driving stage than in the conventional method. Furthermore, this method has been extended to two-degree-of-freedom movements, and the performance of the magnetically driven microtools is experimentally validated by oocyte manipulation.
