Best Practices for Sensor Placement
Accurate sensor placement is critical for collecting reliable data and ensuring your results are repeatable. The Flex cap is designed to align with the international 10-20 system, the standard for EEG electrode placement. To achieve a good connection, part the participant’s hair beneath each sensor location to ensure the hydrated felt pad makes direct contact with the scalp. A gentle wiggle of the sensor can help establish a solid connection. Taking a few extra minutes to confirm that each sensor is properly seated and hydrated will make a significant difference in your data quality and reduce setup-related artifacts.
Optimize Your Data Collection
Once the cap is on, it’s time to check your signals. Open our EmotivPRO software and view the contact quality map. This gives you a real-time, color-coded display of the connection quality for each sensor—aim for all green. Before you start recording, ask your participant to sit quietly for a minute. Have them blink, clench their jaw, and move their head slightly. This allows you to see what environmental and physiological artifacts look like in your data stream, so you can better account for them during your analysis. This simple baseline measurement is an essential step for any academic research.
Troubleshoot Common Setup Issues
Even with careful preparation, you might run into a few hiccups. If you see a poor connection for a specific sensor (indicated by orange, red, or black in EmotivPRO), the solution is usually simple. The most common cause is a dry sensor, so try applying a bit more saline solution directly to the felt pad with a syringe. You can also try wiggling the sensor again to improve its contact with the scalp. If the cap feels loose, double-check that you’re using the correct size and secure it with the included chin strap for added stability during longer recording sessions.

Your Step-by-Step Initial Setup Guide
Getting your Flex system ready is a straightforward process. First, select the correct cap size for your participant to ensure a snug, comfortable fit. Next, prepare your sensors. If you're using the Flex Saline system, soak the felt pads in the provided saline solution until they are fully saturated. Then, insert the hydrated sensors into the desired locations on the cap. The modular design allows you to customize the sensor layout to fit the specific needs of your study, giving you complete control over your electrode montage. Once the sensors are in place, you can gently place the cap on your participant’s head.
Best Practices for Sensor Placement
Accurate sensor placement is critical for collecting reliable data and ensuring your results are repeatable. The Flex cap is designed to align with the international 10-20 system, the standard for EEG electrode placement. To achieve a good connection, part the participant’s hair beneath each sensor location to ensure the hydrated felt pad makes direct contact with the scalp. A gentle wiggle of the sensor can help establish a solid connection. Taking a few extra minutes to confirm that each sensor is properly seated and hydrated will make a significant difference in your data quality and reduce setup-related artifacts.
Optimize Your Data Collection
Once the cap is on, it’s time to check your signals. Open our EmotivPRO software and view the contact quality map. This gives you a real-time, color-coded display of the connection quality for each sensor—aim for all green. Before you start recording, ask your participant to sit quietly for a minute. Have them blink, clench their jaw, and move their head slightly. This allows you to see what environmental and physiological artifacts look like in your data stream, so you can better account for them during your analysis. This simple baseline measurement is an essential step for any academic research.
Troubleshoot Common Setup Issues
Even with careful preparation, you might run into a few hiccups. If you see a poor connection for a specific sensor (indicated by orange, red, or black in EmotivPRO), the solution is usually simple. The most common cause is a dry sensor, so try applying a bit more saline solution directly to the felt pad with a syringe. You can also try wiggling the sensor again to improve its contact with the scalp. If the cap feels loose, double-check that you’re using the correct size and secure it with the included chin strap for added stability during longer recording sessions.

It’s about removing the barriers so you can focus on the science.
Simplify Your Research Logistics
One of the biggest headaches in EEG research is managing the logistics. Traditional systems can be rigid and time-consuming to prepare. The Emotiv Flex system tackles this logistical complexity head-on with its movable sensors and multiple cap sizes. Instead of being locked into a fixed electrode layout, you can place sensors exactly where you need them for your specific study, following the 10-10 or 10-20 systems or a custom montage. This adaptability means you can use the same kit for various experimental designs, simplifying your equipment needs and speeding up your preparation time.
Collect Data in More Environments
Many important insights are found outside the lab. Unlike traditional EEG systems that keep participants tethered to bulky equipment, the Flex’s wireless controller allows you to conduct research in real-world contexts. Imagine studying a student’s focus in an actual classroom, an office worker’s cognitive load during a typical workday, or a consumer’s reaction to a product in a simulated store. This freedom to collect data in more natural environments enhances the ecological validity of your findings, providing a clearer picture of brain activity as it happens in everyday life.
Expand Your Remote Research Capabilities
The Flex system is designed to make high-density EEG research more accessible, which naturally expands your ability to conduct studies remotely.

How to Set Up and Optimize Your Emotiv Flex
The Emotiv Flex is designed for flexibility, but getting the most out of your high-density EEG research depends on a solid setup. Taking the time to properly prepare the cap, place the sensors, and check your signals will ensure you collect the highest quality data possible. Think of this as building a strong foundation for your experiment. A little preparation upfront saves a lot of time in analysis later. Let’s walk through the key steps to get you started, from unboxing your system to troubleshooting common issues.
Your Step-by-Step Initial Setup Guide
Getting your Flex system ready is a straightforward process. First, select the correct cap size for your participant to ensure a snug, comfortable fit. Next, prepare your sensors. If you're using the Flex Saline system, soak the felt pads in the provided saline solution until they are fully saturated. Then, insert the hydrated sensors into the desired locations on the cap. The modular design allows you to customize the sensor layout to fit the specific needs of your study, giving you complete control over your electrode montage. Once the sensors are in place, you can gently place the cap on your participant’s head.
Best Practices for Sensor Placement
Accurate sensor placement is critical for collecting reliable data and ensuring your results are repeatable. The Flex cap is designed to align with the international 10-20 system, the standard for EEG electrode placement. To achieve a good connection, part the participant’s hair beneath each sensor location to ensure the hydrated felt pad makes direct contact with the scalp. A gentle wiggle of the sensor can help establish a solid connection. Taking a few extra minutes to confirm that each sensor is properly seated and hydrated will make a significant difference in your data quality and reduce setup-related artifacts.
Optimize Your Data Collection
Once the cap is on, it’s time to check your signals. Open our EmotivPRO software and view the contact quality map. This gives you a real-time, color-coded display of the connection quality for each sensor—aim for all green. Before you start recording, ask your participant to sit quietly for a minute. Have them blink, clench their jaw, and move their head slightly. This allows you to see what environmental and physiological artifacts look like in your data stream, so you can better account for them during your analysis. This simple baseline measurement is an essential step for any academic research.
Troubleshoot Common Setup Issues
Even with careful preparation, you might run into a few hiccups. If you see a poor connection for a specific sensor (indicated by orange, red, or black in EmotivPRO), the solution is usually simple. The most common cause is a dry sensor, so try applying a bit more saline solution directly to the felt pad with a syringe. You can also try wiggling the sensor again to improve its contact with the scalp. If the cap feels loose, double-check that you’re using the correct size and secure it with the included chin strap for added stability during longer recording sessions.
