FAQ

Need clarification?

What is EEG?

EEG (Electroencephalography) is a technique that records the brain's electrical activity using sensors placed on the scalp or in the ear (like us!). It is commonly used to diagnose and monitor conditions like epilepsy, sleep disorders, and brain function, as well as in research and neurotechnology applications.

I don’t know anything about EEG, can i still work with the IDUN Guardian?

Yes, you can still work with the IDUN Guardian. Our device comes with an extensive list of classifiers that analyze the raw EEG data for you, such as frequency band classification, jaw clench, and eye movement detection, making it easy to develop applications even without prior EEG knowledge.

Is in-ear eeg a reliable method of measuring eeg?

Yes, in-ear EEG is a reliable method for measuring EEG. It provides accurate brain activity data comparable to traditional scalp EEG, making it suitable for various applications like focus tracking, fatigue detection, and sleep monitoring.

What is the difference between in-ear EEG and a traditional Full Scalp set up?

In-ear EEG measures brain activity using sensors in the ear, offering convenience and comfort, while traditional full scalp EEG uses multiple sensors placed on the scalp for broader spatial recognition. In-ear EEG is less obtrusive and easier to use but may not capture the same level of detailed spatial information as a full scalp setup.

Does it have audio?

Not at the moment, but audio functionality will be available by the end of the year. Currently, the earbuds have an air canal, so external sounds are not blocked out.

How many channels does the IDUN Guardian have?

The IDUN Guardian is a single-channel EEG device that records the signal from within the ear.
