Headset paves way for wireless EEG monitoring

A next generation, wireless electroencephalography (EEG) headset has been unveiled by imec and Holst Centre.

The device combines dry electrodes with integrated skin-to-electrode impedance monitoring to provide information about the contact quality throughout the entire EEG recording. Signal processing is integrated to cancel out motion artefacts. What's more, a motion artifact handling approach was developed for the device, based on band-pass and adaptive filtering, which is said to substantially reduce the contamination of the EEG recordings due to motion and it can operate in real-time. While EEG measurements are typically performed by trained professionals in hospitals, with this headset imec says wireless EEG monitoring could soon be carried out reliably in the home.
