Imec, Holst Centre and Panasonic have developed a new prototype of a wireless EEG (electroencephalogram) headset. The system combines ease-of-use with ultra-low power electronics. Continuous impedance monitoring and the use of active electrodes increases the quality of EEG signal recording compared to former versions of the system. The data are transmitted in real-time to a receiver located up to 10m from the system. The realization of this prototype is a next step towards reliable high-quality wearable EEG monitoring systems.
The system integrates circuit level components including imec's active electrodes and EEG amplifier together with a microcontroller and a low power absdc.
