Product Description
EMOTIV FLEX 2 Saline – 32-Channel Wireless EEG Headcap System - DIY Kit
Precise EEG Measurements with Flexible Application
The FLEX 2 Saline is a portable, wireless 32-channel EEG headcap system designed for advanced use in neuroscience research. It enables high-resolution recording of brain activity in various environments, both in the lab and in the field. The saline-based electrodes provide sustained conductivity with minimal need for interruptions. Integrated Bluetooth® 5.2 technology ensures accurate real-time signal transmission, supported by refined sensors and a robust antenna design. FLEX 2 Saline is well suited for mobile research, behavioral studies, BCI projects, and EEG-based analysis outside of traditional laboratory settings.
