IntroductionElectrodes are the things that you place on yourself to detect electrical current; in the case of OpenEEG, you place them on your head to detect brainwaves. There are two basic types of electrodes, Active and Passive.
Active ElectrodesActive electrodes are electrodes with some built in circuitry which amplifies the electrical current. This greatly improves the signal quality received by the modularEEG and avoids the skin preparation and conductive paste required by normal passive electrodes (i.e. no more goo in your hair!).
This involves more work than passive electrodes, but produces better results.
Passive ElectrodesPassive electrodes have no inbuilt circuitry. There are a variety of different types. More information can be found on the Passive Electrodes page.
