Belgium's Imec research institute showed the latest version of a headset that acts as a wireless brain wave monitor, geared for applications ranging from monitoring seizures in epileptic patients to helping paraplegics use thoughts to control a keyboard.
The electroencephalogram can read eight channels continuously for 1.5 days with a 25dB signal to noise ratio. The headset uses an eight-channel analog readout ASIC from Imec, a Nordic Zigbee radio and off-the-shelf EEG sensors.
For the next-generation of the headset, Imec is investigating its own designs for dry sensors and 2.4 GHz or ultrawideband radios. The project is part of the group's Human++ project that now includes members from medical electronics and system integration companies.
