本文提出了一种微操作系统的建模和开发，可以提供连续的力，通过外部施加的磁场操纵一个微小的颗粒。该系统由六个电磁线圈组成，可操纵的微粒尺寸小于30μm。首先使用有限元方法模拟从电磁体产生的磁场图。根据计算结果，我们可以计算出系统所能提供的力。设计并构建了一个系统原型，用于精确控制超顺磁性微珠在微流控环境中的导航。该系统可用于药物输送以及医疗应用，如微创手术，诊断和传感。
This paper presents the modeling and development of a micromanipulation system that can provide continuous force to manipulate a micro-particle through an externally applied magnetic field. This system consists of six electromagnetic coils and the size of the micro-particle to be manipulated is less than 30μm. The magnetic field maps generated from the electromagnets are first simulated using a finite element method. Based on the result, we then calculate the force that can be provided by the system. A prototype of the system is designed and constructed, which is used to precisely control the navigation of a super-paramagnetic micro-bead in a microfluidic environment. This system can be used for drug delivery as well as medical applications such as minimally invasive surgery, diagnosis and sensing.
