g.SAHARA - Active Hybrid Electrode System (DRY)

Normally, the electroencephalogram (EEG) is recorded from the surface of the head with gel-based electrodes to provide a low electrode- skin impedance. If passive electrodes are used, the skin must be abraded beforehand to reduce the impedance. With active electrodes, which contain an amplifier inside, the electrode gel is injected between the electrode material and the skin. This allows the electrode system to be mounted more quickly. One of the main advantages of gel-based active electrodes is their robust signal quality, but the main disadvantages are the long mounting time and the need to wash the cap and the user's hair after the recording. g.tec thus developed a dry electrode system that does not require electrode gel. The patented g.SAHARA electrode system consists of an 8 pin electrode made of a special golden alloy. The pins have sufficient length to reach through the hair to the skin. The golden alloy and the 8 pins reduce the electrode-skin impedance.

g.GAMMAsys is designed to work with all g.tec amplifiers. It includes different types of active and passive electrodes that are connected via g.GAMMAbox to g.USBamp and can be mounted with the g.GAMMAcap onto the head for EEG recordings, or can be mounted on the body for ECG/EMG/EOG recordings. The g.GAMMAcap can be configured with electrodes for a certain experiment (such as the P300 speller), and the electrodes remain inside the cap even during cleaning. This makes preparation and cleaning very fast, which speeds up experiments considerably. A typical setup time for a P300 speller experiment (10 electrodes) is about 2 minutes–just put on the cap and inject the gel. After the cap is removed, the gel almost disappears after some time, and gel is removed completely by washing the hair
