Emotiv Flex 2 Gel Sensor Cap – 32-Channel EEG System

EMOTIV FLEX 2 Gel – 32-Channel Wireless EEG Head Cap System

High-performance wireless EEG solution for advanced research applications

The FLEX 2 Gel – 32-Channel Wireless EEG Head Cap System is a state-of-the-art device designed to record electrical brain activity with precision. Developed for research environments requiring flexible, high-resolution, and wireless data acquisition, this system features a 32-channel cap with standardized electrode placements based on the international 10-20 system. The gel-based electrodes ensure consistent signal quality, even during extended recording sessions.

Its integrated controller wirelessly transmits EEG data with high temporal accuracy, making it particularly suited for capturing event-related potentials (ERPs) during visual and auditory stimuli. Enhanced with Bluetooth® 5.2 and an optimized antenna design, it provides stable, real-time data transmission.

The system also includes motion sensors, various cap sizes for customized fit, and a protective carrying case, making it ideal for mobile research applications and long-duration EEG recordings.
