BrainAccess Electrodes
BrainAccess systems utilize in-house manufactured gold-plated
dry-contact electrodes, designed for durability, biocompatibility, and high
signal stability in portable EEG applications.
Additionally, Datwyler SoftPulse™ electrodes are available as add-ons.
Neurotechnology’s Gold-plated Dry-Contact Electrodes
Overview
Durability and corrosion resistance
Gold’s resistance to oxidation and corrosion ensures consistent long-term performance, critical for portable EEG setups.
Stable impedance over time
Stable electrode impedance even after repeated cleaning for reliable, low-noise signal acquisition over time and repeated use.
Biocompatibility and skin safety
Gold is biocompatible and hypoallergenic, minimizing irritation during prolonged skin contact.
Enhanced contact through nanostructuring
Nano-textured spring-loaded pins that gently part hair strands and establish consistent skin contact.
Environmental stability
Gold-plated electrodes are resistant to environmental aging and maintain performance under a wide range of conditions.
Two variants available
Spring-based electrodes with 12 spring-loaded pins for hair-covered areas or flat-pad electrodes with circular pads for hair-free regions.

SoftPulse™ Electrodes
Overview
Extended Comfort
Soft, skin-conforming interface that ensures stable bio-signal acquisition while maintaining exceptional user comfort during prolonged wear.
Biocompatibility and skin safety
Soft rubber compound material with Ag/AgCl coating on skin-facing surface. Certified for skin irritation and sensitization
Reusablility
Can be reused up to 100 times without compromising comfort or signal performance, making them cost-effective and reliable.
Excellent performance
Strong signal quality, good impedance, fast equilibration time, and excellent stability while ensuring comfort.
Multiple variants
Multiple shapes to accommodate different hair types, including flat pads for the forehead and hair-free regions.
Available as add-ons
Available as optional add-ons to all the BrainAccess Kits for users who require enhanced comfort or more flexible configurations.
