Dry Electrodes

Industry-Leading Dry Electrodes

Dry Electrodes

No Skin Preparation

Patented dry electrodes allow high-fidelity EEG signal acquisition with no skin abrasion or preparation.

No Gels

Ultra-high impedance amplifiers mean that DSI sensors require no gels or fluids, and consequently do not leave any messy residue. All contacts are completely dry, no sticky or wet pads anywhere! This allows for irritation-free, long-term recordings, without risk of drying out!

Through Hair Operation and Comfort

Round-ended pinned active electrodes contact the scalp through hair and provide comfortable contact.

Uncompromising Signal Quality

Signal quality is comparable to that obtained from conventional wet electrodes, with >90% correlation.


Mechanical and engineering designs eliminate motion and electrical artifacts WITHOUT the need for advanced filtering!

Convenient Headset Designs

Rapid Set-up

Easy-to-use headsets are typically self-donned in under 5 minutes with minimal or no adjustments needed.

Even More Rapid Removal

Easy-to-use headsets are instantly taken off and do not require subjects to wash their hair afterward.

Ambulatory and Wireless

Fully integrated batteries, amplifiers, digitizers, and Bluetooth transmitter allow for ambulatory use

10/20 Locations

Headsets are designed to automatically and reproducibly position sensors according to the International System 10/20 on a wide range of head sizes.


Padding and spring-loaded designs provide for long-term wearable comfort unrivaled in the field of EEG. Headsets do not require chin-straps!
