Advancing High-Density EEG Research with Flex

The Emotiv Flex system revolutionizes high-density EEG research with its movable sensors, multiple cap sizes, and advanced saline-based electrodes. Designed for real-world applications, the Flex Saline Kit ensures millisecond-level accuracy and seamless wireless data transmission via the Flex Controller, allowing for natural and dynamic brain activity measurements.

Validation & Expert Review

For researchers seeking validation of the Emotiv EPOC Flex Saline for EEG and ERP studies, refer to the published article: “Validation of Emotiv EPOC Flex Saline for EEG and ERP Research.” Dr. Nikolas Williams from Macquarie University, Australia, reviewed the EPOC Flex Saline, stating: “Very user-friendly. The felt pads make setup a breeze, and I am pleased at how fast and easy it has been to get the sensor connections stable.”

Emotiv Flex Configurations

We offer three configurations to suit different research needs:

• Pre-configured Flex Saline – Comes with a predefined sensor layout for faster setup and optimized research workflow.
• Non-configured Flex Saline – Offers flexibility in electrode placement based on specific research requirements.
• Non-configured Flex Gel – For researchers preferring gel-based electrodes for their studies.

Electrode Placement in the Pre-configured Flex Saline

Researchers using the pre-configured cap benefit from faster setup times, ensuring quick and efficient data collection. The pre-configured Flex Saline cap includes the following electrode positions: AFz (DRL), FCz (CMS), Fp1, Fp2, F7, F3, Fz, F4, F8, FT9, FC5, FC1, FC2, FC6, FT10, T7, C3, Cz, C4, T8, CP5, CP1, CP2, CP6, TP9, TP10, P7, P3, Pz, P4, P8, O1, Oz, O2.

Select the right Flex cap size for your Flex kit

For the Flex Gel and Flex Saline Kit, please select a cap size based on head circumference, measured along the line where a hat would sit. Cap sizes increase in 2 cm increments (even numbers). If the measured circumference falls between sizes (an odd number), choose the next larger size.

Example:

• A head circumference of 52.5 cm to 54.4 cm → Choose size 54
• A head circumference of 55 cm → Choose size 56

For individuals with long or thick hair, measure over the hair. If the selected cap feels too loose (e.g., Pz electrode not making contact), try the next larger size.
