论文摘要
介电性电泳的电动作用是在微观和中尺度上诱导一类可极化物体的力和扭矩的一种有前途的方法。我们基于这种现象引入了一种非接触式微操纵技术，该技术能够同时定位和定向各种形状的微观对象。采用了基于基于实时优化的数学模型反转的视觉反馈控制。在用四极电极阵列上执行的俄罗力四型SU-8微型对象的一系列实验中证明了所提出的操纵方法。使用更多的电极，该方法很容易与生物学和微型组装应用中的多个对象同时操纵。
The electrokinetic effect of dielectrophoresis is a promising way of inducing forces and torques on a broad class of polarizable objects at micro- and mesoscale. We introduce a non-contact micro-manipulation technique based on this phenomenon, which is capable to simultaneously position and orient a micro-object of various shapes. A visual feedback control based on a real-time optimization-based inversion of a mathematical model is employed. The presented manipulation approach is demonstrated in a series of experiments with Tetris-shaped SU-8 micro-objects performed on a chip with a quadrupolar electrode array. Using more electrodes, the method is readily extensible to simultaneous manipulation with multiple objects in biology and micro-assembly applications.
