Pin-Type Active-electrodes
The BioSemi "Pin-type" Active electrode has been designed especially for mounting in BioSemi headcap's. The electrode has a sintered Ag-AgCl electrode tip, providing very low noise, low offset voltages and very stable DC performance.
Standard sets have 32 electrodes on a common connector with 140 Centimeter cable length. (Other cable lengths are available on request.) The electrode is completely resistant to long term water and alcohol submergence enabling easy cleaning and disinfecting. The electrodes are numbered with water-proof stickers for easy channel recognition.

128 channel Active-headcap
 
The BioSemi headcap is a novel concept for high density EEG measurements. The plain cap only exists of the electrode holders. No electrodes or wires are attached to the cap. This allows for very fast placement of the electrodes according to the procedure described below. Preparation times as low as 30 minutes for a 128 channel EEG headcap are realistic.
Because of the Active electrode principle, high electrode impedances do not influence the signal quality. Therefore, any skin preparation can be completely omitted.
The location of the electrodes can be easily determined by the user, more info can be found in the "Make Cap Question"
 
 
 
Step 1
 
Step 2
 
Step 3
 
 
Place headcap over the head.
  
Apply electrode gel in holes. No further scrubbing of the skin necessary !
