Field Electrodes

 
Field Electrodes

Field electrodes are used to conduct electrical current and generate electrical fields for controlling electroosmotic flows or to perform electrophoresis. These electrodes are typically made of platinum to resist corrosion.


Position

For most applications the electrodes are positioned on the top surface of the glass chip. A major benefit of field electrodes that are placed on top of the chip compared to electrodes that are in between glass layers is the more economical processing costs. However, integrating field electrodes between layers is also possible.
