Product Introduction:
The Greentek Gelfree S3 Electrode Cap is a gel-free EEG electrode cap designed for high-performance and convenient EEG acquisition. Utilizing advanced semi-dry EEG electrode technology, the cap enables fast and reliable EEG signal recording without the need for conductive gel, significantly simplifying the setup process.
The cap integrates Ag/AgCl electrodes that provide high signal-to-noise ratio, stable signal quality, and strong anti-interference performance. With Greentek’s proprietary Hydro-link™ technology, saline is precisely and slowly released to maintain stable electrode–scalp contact, enabling continuous EEG recording for extended sessions without gels.
The cap shell is made of breathable elastic fabric and features a double-layer structure with a hidden cable design, providing both improved durability and an attractive, streamlined appearance.
The Gelfree S3 Cap is suitable for a wide range of applications, including neurofeedback, rehabilitation medicine, mental health and cognitive rehabilitation, brain-computer interface (BCI) research, and cognitive neuroscience studies.
Key Features:
- Pure silver/silver chloride electrode, with high signal-to-noise ratio
- Lingke cotton sustained-release saline technology—no conductive paste required.
- Double-layer shell, cable-hidden design, beautiful and durable.
- A 2-hour-long EEG recording with stable signal quality.
- The patented electrode holder design facilitates the easy installation, removal, and handling of electrodes on the scalp.
Specifications：
- AC impedance ≤ 2.5 kΩ·cm² (@10 Hz)
- DC offset voltage ≤ 30 mV
- Potential drift ≤ 5 mV/10 min
- Resistance ≤ 5 Ω
