Emotiv Flex 2 Saline Sensor Cap 32 channel EEG preconfigured

Product Information

Mobile EEG system for versatile research applications

The EMOTIV FLEX 2 Saline is a portable EEG system with 32 channels, developed for professional use in neuroscience, psychophysiological, and technology-oriented research environments. This preconfigured version includes all essential system components, matched and ready for immediate use—no additional setup or customization required. With wireless data transmission, saline-based sensors, and adjustable cap sizes, the system ensures high-quality data while remaining flexible for both stationary and mobile research setups.

The electrodes operate using a saline solution and can be easily rehydrated for longer sessions without interruption. Wireless transmission is supported via Bluetooth® 5.2 or the included USB receiver. A built-in 9-axis motion sensor enables synchronized acquisition of EEG and movement data. The system is particularly suited for research areas such as brain-computer interfaces, cognitive studies, and EEG-based interaction concepts.
