very robust and easy to use

unique adjustable bayonet sockets guarantee a slight pressure of the electrode on the skin (for best impedance values)

ultra-flexible and light-weight electrode cables (100 cm) with safety connectors

hermetic sealing of connection between electrode and cable

gold (Au) electrodes (maintenance-free) or chloridable silver (Ag/AgCl) electrodes available

The left panel shows the electrode positions of the fully equipped 65-electrodes cap.

This configuration is suitable for most studies. If you need other positions or a subset ask for a customized solution.

Best results are obtained when preparing the skin with an abrasive gel (see electrode montage).

The systems are very capable. If you want to work with 2 or with 111 channels, we do have the best solution for your measurement.

An additional pre-amplifier is located inside the electrode itself. The system is designed for use with biosignal amplifiers with monopolar (unipolar) inputs. It can be used with g.BSamp, g.USBamp and with g.MOBIlab+. Bipolar (differential) recordings are possible with recording systems capable of computing differential derivations from unipolar signals (e.g. g.USBamp). Electrodes are made of sintered Ag/AgCl and work in a frequency range of 0 - 100 kHz. The active electrodes can be used with the g.EEGcap as an alternative to the passive standard electrodes.
The system avoids or reduces artifacts and signal noise resulting from high impedance between the electrode(s) and the skin (e.g. 50/60 Hz coupling, artifacts caused by electrode or cable movements, distorted signals or background noise). No modifications are required for the biosignal amplifier which can be used with or without the active electrode system.
