Abstract: PURPOSE: A microbead separator and a manufacturing method thereof are provided to broaden the area of a minute electrode track by using a multilayered bus bar design technology. CONSTITUTION: A microbead separator using multilayered bus bar includes a multilayered bus bar(11-14) and an electrode track(35). The bus bar supplies different phases. The electrode track is connected to the multilayered bus bar. The multilayered bus bar classifies a great amount of minute particles by broadening the area of the electrode track. The electrode track includes a plurality of minute electrodes in parallel. The electrode track forms an electromagnetic field gradient between minute electrodes. The minute particles are classified by being trapped in a specific location according to a physical property.

Abstract: 개시된다층버스바를이용한미세입자분류기는, 서로다른위상을공급하기위한다층버스바와상기다층버스바에연결되는전극트랙을구비하고, 상기다층버스바를이용하여상기전극트랙의면적을넓혀다량의미세입자를분류하는것으로서, 다층버스바 구조를통해기존버스바의저항문제를제거함으로써, 넓은면적의 TwDEP 칩을제공해주게되며, 미세전극간의간격에전기장구배(gradient)를형성하여, 전극들간에간격이 10㎛부터 40㎛까지점진적으로증가하도록미세전극트랙을구현함으로써, 미세입자에작용하는중력, TwDEP힘과네거티브 DEP힘의균형이이루어지는위치가미세전극트랙에따라점진적으로변화하여, 최종적으로미세입자를그들의물리적속성(크기, 전기적속성)에따라특정위치에트랩시켜분류하게되는것이다.
