New-Generation Quik-Cap Electrode Arrays

Compumedics Neuroscan manufactures a variety of Quik-Cap™ Electrode Arrays to meet your EEG recording requirements. For long-term users of the Quik-Cap, we will continue to provide the manufacturing of the traditional Quik-Caps.

The new line of Quik-Cap Electrode Arrays offers a number of innovations.

Presenting two new classes of Compumedics Neuroscan Electrode Arrays

Gel-based Electrode Arrays

The Gel-based Electrode Arrays feature low-profile electrodes embedded in soft silicone rubber reservoirs for added wearer comfort and to facilitate the retention of electrode gel at the site of application.

The flatter and smaller diameter electrodes, allow for sufficient separation for high density recordings up to 256 channels, while minimizing the potential for salt bridges between electrodes, and at all times ensure that electrode impedances can be obtained below the EEG discipline standard of 5 kOhms.

Gel based Electrode Arrays are offered in two shell materials Neoprene (the Quik-Cap Neo Net Electrode Array) and a Silicone (the Quik-Cap Silicone Electrode Array).

The advantage of the Neo Net is great comfort, however the neoprene wetsuit like material must be rinsed and allowed to dry between recording sessions, which can limit the use of the cap to once per day.

The Silicone Electrode Array, on the other hand, can be ready to use again within moments. The shell is essentially water-proof, so with a rinse and wipe down with a dry towel it can be turned around quickly.

Liquid-Electrolyte Hydro Net Electrode Arrays

The Hydro Net Arrays use liquid electrolyte absorbent foam enclosed by a soft silicone rubber reservoir/holder to facilitate rapid applications and recordings. The Hydro Net Quik-Caps can achieve stable impedances as low as 5 -10 kOhms for up to 3 hours. The silicone rubber reservoir that surrounds the electrode impedes evaporation of the liquid electrolyte, thus lengthening recording sessions.
